Ha ha ha. Mister Shitpants was my dad. You can call me Doctor Shitpants. Are things not-so-fresh down there? Does it take you a long time to get off the john when you go to poop? Do you start dropping the kids off at the pool, only to gradually forget why you were there during the passage of time, becoming a new person in the process, untethered from personal responsibility as a result of your harrowing journey?

There is news, and that news is good. Friends, I have been called to a purpose higher than any on Earth. That purpose is to have a good, high-speed shit. Before I go into my sales spiel, I just want to give you a couple of facts to sit with. Fact number one: fully one-twelfth of a human being's lifetime is spent taking a dump. That's absolutely true. And fact number two: we got better things to be doing with our time than pooping.

Have you ever wondered why, in this time of automation and high technology, where robots do our menial tasks such as writing poetry and drawing grotesque pornography, we still have to strain so hard to use the toilet? That's where the Shitpants 9000 fecal vacuum comes in. It's patented, so don't go sniffing around under those covers, boys. I know you're really here from Toto's espionage department.

Don't worry: this isn't like the old fecal vacuums, like the McDonnell-Douglas nightmare of the 1960s that turned all those senior citizens inside out. Microcontrollers and adaptive suction engines are used to ensure that the pressure is gentle, even, but insistent. You'll be done your business in less than half the time you used to spend, which means more time for what's really important: using your phone on the john in order to avoid going back to work.

For future reference (my own and others), if your TI SilverLink USB cable stops working and starts showing up as "TUSB3410 Boot Device" or similar under device manager (AKA this issue on TI's help page), this is how you can fix it:

Download the TUSB3x10 EEPROM Burner. This is a Windows-only program, but to my knowledge will work on basically any windows machine from XP on -- so long as it's got USB ports. No clue if it'll work in a VM. (You might want to consult this user's manual.)

Download the SilverLink firmware. I got it from here, and compiled it from their de-compilation. It's just a standard 'make' to build. The output file you're looking for is called "ti_graph_link_silver.eep".

Rename "ti_graph_link_silver.eep" to "ti_graph_link_silver.bin".

Open the TUSB3x10 EEPROM Burner, click on the options dropdown and click "Show the 'Program Full Binary Image' button". (page 7 of the manual).

Select the entry under "Computer" labeled "TUSB3410 EEPROM Burner Instance (1.00)".

Set EEPROM size to "64Kb".

Set "File Path" to point to "ti_graph_link_silver.bin". (The renamed .eep, not the original .bin)

I don't know if the VID, PID, Manufacturer string, Product string and Serial # need to be set manually or not with a 'Full Binary Image' burn. Just to be safe, I set VID to 0451, PID to e001, Manufacturer to "Texas Instruments", Product to "TI-GRAPH LINK USB", and checked "Not Serialized"*.

Click the "Program Full Binary Image" button (yellow triangle with the exclamation point), and proceed with the write.

Unplug and re-plug your cable, and it should show up as a SilverLink again!

Additional notes:

The reason that this happens is because the SilverLink cable (revision b, at least) is based on the TUSB3410 microcontroller. That microcontroller's boot process involves checking for an I2C EEPROM containing program code. If it finds that EEPROM and its contents are properly formatted, it'll copy that code into internal RAM and start executing it. If it can't find the EEPROM, or its contents aren't properly formatted, it'll fall back to looking for boot code over USB. Thus: "TUSB3410 Boot Device". Your cable has, in essence, forgotten who it is and and is begging for you to give it a purpose.

The default page-write buffer size (32 bytes) and I2C bus speed (400 KHz) in the burner app are already correct, so no need to change them.

*I don't remember exactly what the Manufacturer string, Product string, or serial number fields were set to pre-corruption. Likewise, no idea about the advanced descriptor options. If someone wants to send the output of lsusb -v -s [whatever their silverlink's bus/id numbers are], I'd really appreciate it!

You might be able to skip the header rigamarole by taking the ti_graph_link_silver.bin file directly ("directly coming from the compiler") -- but I again I don't know exactly what information is in the .eep file and what isn't. Are the PID and VID encoded somewhere in there? I peeked with a hex editor but have no clue. If someone has hardware lying around they're willing to experiment with/potentially brick, I'd love to hear your results!

If you mess up and accidentally forget to do a "Full Binary Image" write, or otherwise brick the firmware, you can force the TUSB3410 to fall back to USB boot mode by opening the plastic shell around the PCB (one Torx screw under the sticker, then just normal plastic tabs) and shorting the right-bottom (Vss) and right-top (SDA), or right-bottom (Vss) and center right-top (SCL) pins of the EEPROM (the chip labeled "24LC64") as you plug it into the USB port. You may need multiple attempts. This works because it temporarily convinces the TUSB3410 that the EEPROM is missing/corrupt, and thus it decides to fall back into USB boot mode -- until you reset it. It might be better to do this with a ~1k resistor instead of a jumper wire, but IDK I'm not an electrical engineer. All I know is that shorting Vss and SDA worked for me. Again, would love feedback.

No clue what causes the corruption in the first place, or how long this fix will last. It might be because the EEPROM's write protect pin is set to "write enable"? It could also just be degrading hardware, for all I know, so no idea how long the fix will last. All I do know is that everything seems nominal right now (immediately after performing this procedure).

WARNING: LONG ASK INCOMING

For hobby electronics there’s two major kinds of processors: Microcomputers and Microcontrollers. Microcomputers are small full computer systems like the Raspberry Pi, they typically run a general-purpose OS (typically some flavor of Linux) and are useful for the kinds of projects that require basically a full computer to function, but not necessarily individual sensors. They’re a great place to start for people who don’t know a whole ton about programming or working with individual components because they typically can output a true GUI to a screen and have the capabilities of a regular desktop computer. They have a main processor, true RAM, and either large on-board storage space or a way to read a storage device, like an SD card.

Microcontrollers are less complicated (component wise) than microcomputers, but as a result are more difficult for total beginners to begin working with. They’re typically primarily a SoC (System on a Chip) processor without discrete RAM modules and a very small EEPROM (on-ship storage space) and need to have components wired and configured to them to be able to do much more than being a fancy calculator. They’re used for when you need something to carry out electronic functions or get sensor readings, but not necessarily a full operating system, so they’re best suited for small/integrated applications. Your helmet uses a microcontroller to control the LEDs you used in the Cunt Machine post.

I build high-power model rockets as a hobby and with my university team, so I work with both kinds of processor as part of designing payload systems. I typically prefer microcontrollers in these as most of what we do doesn’t need an actual OS to run, and they’re smaller/lighter than microcomputers. One of the advantages of a microcontroller is that it runs a Real-Time OS (RTOS) which forgoes all the user-friendliness of things like windows and linux to instead be the bare minimum backend necessary to run code uploaded into the processor. 

The main advantage of using a microcontroller is really that they’re typically a lot cheaper than microcomputers are and are plenty powerful for really embedded applications. They also make other parts of whatever system is being built cheaper/easier to integrate because they require less overhead to function - the raspberry pi needs a minimum of 5 volts of power to work, while a chip like an ESP32-PICO can run at 1.8V. 

The main way you make sensors/buttons/peripherals work with a microcontroller is via digital communication busses. There’s a few protocols, the most common being I2C, SPI, and UART. I’ll talk about I2C since that’s generally the most common. With I2C each component is assigned a 2-byte “address” that they’re identified by. When the controller sends a request signal on the I2C data bus, every sensor along the line will return their own signal, marked with their address so that they can be identified. It allows for a large number of devices to be put on the same lines and you can daisy-chain them through each other to the microcontroller.

I’ll be honest I really can’t think of a good way to say much more on the subject as like a starting message because I’ve been working with computers so long all the tech stuff for me is second nature, but if you have any questions ask away I can probably answer them or google them.

The Evolution of Embedded Hardware: From Simple Circuits to Smart Devices

Embedded systems are all around us in today's hyperconnected world, from the sophisticated electronics controlling your car's engine to the smart thermostat that regulates the temperature in your house. One of the most amazing changes in technology is the progression from simple circuits to the advanced smart devices of today. This evolution, which has been fuelled by necessity and creativity, has been an intriguing one that has taken place over many decades. Understanding this history is essential for developers and businesses traversing this terrain, particularly when thinking about an embedded hardware design service that could help them realise their next big idea.

The Pioneer Days: Early Embedded Systems

The 1960s and 1970s marked the dawn of embedded computing, though it looked nothing like what we recognize today:

The Apollo Guidance Computer, which helped navigate astronauts to the moon, represented one of the first mission-critical embedded systems

Early embedded systems relied on discrete components rather than integrated circuits

These systems were enormous by today’s standards—filling entire cabinets

Programming was done through hard-wired logic or assembly language

Each system was custom-designed for a specific purpose with little flexibility

These primitive beginnings laid groundwork for what would become a technological revolution, yet the limitations were substantial. Memory was measured in kilobytes, processing power was minimal, and development required specialized expertise that few possessed.

The Microprocessor Revolution

Everything changed in the early 1970s with the introduction of the microprocessor:

Intel’s 4004, introduced in 1971, became the first commercially available microprocessor

For the first time, computing power could fit on a single chip

Development costs dropped dramatically, making embedded systems accessible to more industries

Early applications included calculators, cash registers, and industrial controllers

The 8-bit microcontroller era began, with chips like the Intel 8051 becoming industry standards

This miniaturization represented the first major leap toward modern embedded systems. Suddenly, intelligence could be added to previously “dumb” devices, creating new possibilities across industries from manufacturing to consumer electronics.

From Industrial to Consumer Applications

The 1980s and 1990s witnessed embedded systems transitioning from purely industrial uses to consumer products:

Video game consoles like the Nintendo Entertainment System introduced millions to embedded technology

Household appliances began incorporating microcontrollers for improved functionality

Automotive applications expanded rapidly, with engine control units becoming standard

Personal digital assistants (PDAs) showcased the potential for portable computing

Cell phones emerged as perhaps the most transformative embedded systems of the era

At this time, there started to appear specialized embedded hardware design service providers which assists businesses with intricate hardware designs. These services helped translate creative concepts into functioning products, allowing companies without internal capabilities to join the growing competition in the electronics industry.

The Networking Revolution and Embedded Connectivity

By the late 1990s and early 2000s, embedded systems gained a critical new capability—connectivity:

First-generation embedded networks often used proprietary protocols

Industry standards like CAN bus revolutionized automotive electronics

TCP/IP implementation in embedded devices paved the way for Internet connectivity

Wireless technologies like Bluetooth and later Wi-Fi liberated devices from physical connections

Remote monitoring and management became possible, changing service models forever

This networking capability transformed embedded systems from standalone devices to interconnected nodes, creating new possibilities for data collection and device management. Industries from healthcare to manufacturing began reimagining their processes around these newly connected devices.

The Rise of the Internet of Things (IoT)

The 2010s saw embedded systems become truly ubiquitous through the Internet of Things:

Consumer IoT products like smart thermostats, lighting, and speakers entered millions of homes

Industrial IoT revolutionized manufacturing through predictive maintenance and asset tracking

Agriculture embraced precision farming techniques using embedded sensor networks

Healthcare innovations included remote patient monitoring and smart medical devices

Urban infrastructure began incorporating embedded systems for “smart city” initiatives

With this explosion in applications came increasing complexity. An embedded hardware design service became essential for many companies looking to enter the IoT market, providing expertise in not just hardware but the integration of sensors, connectivity, and power management that modern IoT devices require.

The Miniaturization Miracle

Throughout this evolution, one trend has remained constant—the drive toward smaller, more efficient devices:

Component sizes shrank from through-hole to surface-mount to microscopic

Power consumption decreased dramatically, enabling battery-operated portable devices

Wearable technology emerged as components became small enough to integrate into clothing and accessories

Medical implants shrank to minimize invasiveness while increasing capability

Sensors became small and inexpensive enough to deploy in massive numbers

This miniaturization has opened new frontiers in what’s possible with embedded systems. Today’s embedded hardware design services often specialize in extreme miniaturization, developing sophisticated systems that fit into spaces previously thought impossible.

The Processing Power Explosion

Modern embedded systems bear little resemblance to their ancestors in processing capability:

32-bit and 64-bit processors have replaced 8-bit chips in many applications

Multi-core processors enable complex real-time processing

Specialized hardware accelerators handle tasks like AI inference and video processing

For specific applications, field-programmable gate arrays (FPGAs) offer hardware that can be reconfigured.

 System-on-Chip (SoC) designs combine peripherals, memory, and CPUs into one unit.

With this processing capability, embedded systems can now perform tasks like computer vision and natural language processing that were previously only possible with general-purpose computers, all while retaining the dependability and deterministic behaviour that embedded systems need.

The Future: AI at the Edge and Beyond

Looking ahead, embedded systems continue evolving at a breathtaking pace:

Edge AI is pushing intelligence to embedded devices rather than relying on cloud processing

New materials and manufacturing techniques are enabling flexible and biodegradable electronics

Energy harvesting is reducing or eliminating battery dependencies

Quantum computing principles may eventually transform embedded processing

Neuromorphic computing aims to make embedded systems think more like biological brains

These frontiers represent both challenge and opportunity. Companies seeking to navigate this complexity increasingly turn to specialized embedded hardware design services that can transform cutting-edge concepts into viable products.

The evolution of embedded hardware marks one of the most remarkable journeys of technology, progressing from circuits to devices that think for us and are a part of our lives.

Notes on Self-Studying STM32F10x Microcontroller Interrupts

Having previously used PIC and 8051 microcontrollers, I had never encountered the STM32 series of chips. Recently, I began delving into the STM32F10xseries.

During my studies, I found the STM32's interrupt system to be quite distinctive compared to those of the PIC and 8051, particularly in its response mechanism. Despite going through manuals and video tutorials multiple times, I still felt somewhat confused. However, as I began coding to configure the chip, I gradually started to understand it better. This led me to document my experiences as summary notes. I acknowledge that there may be some inaccuracies or gaps in my descriptions, and I encourage feedback and corrections.

The STM32 is built on the ARM Cortex-M3 core, which supports up to 256 interrupt sources. Out of these, 16 are core-specific, while up to 240 can be attributed to external devices. Each interrupt source has an independent priority control register, which is an 8-bit register. In theory, this means each interrupt source within a complete Cortex-M3 core could have 256 levels of priority. However, this vast architecture pertains to the entire Cortex-M3 core.

In the case of STM32 chips, not all possible interrupt sources or priority levels are used. Specifically, our STM32 model has the core's 16 interrupt sources and 68 additional sources from external devices. Since the STM32 doesn’t exploit all the interrupt sources available with the Cortex-M3, it also doesn't offer the full spectrum of 256 priority levels for configuration. Instead, the priority setting registers for each interrupt source in the STM32 use only the upper 4 bits of the 8-bit register. Details can be seen in the diagram below:↓

In STM32 microcontrollers, interrupt priorities are set using a priority register where each interrupt source has 4 bits allocated for this purpose. These 4 bits are divided into two groups: the "preemptive priority" (higher bits) and the "subpriority" (lower bits). The preemptive priority determines if an interrupt can interrupt currently executing interrupts, while the subpriority resolves conflicts between interrupts with the same preemptive priority.

The configuration of these priorities is managed by the Application Interrupt and Reset Control Register (AIRCR), specifically using bits 10, 9, and 8, known as the "PRIGROUP" bits. These bits define how the 4-bit priority is split between preemptive priority and subpriority, establishing different grouping schemes. For example, setting PRIGROUP to 101 configures the system to use 2 bits for both preemptive and subpriority levels, allowing values from 0 to 3 for each.

According to Cortex-M3 specifications, regardless of how many bits are used for priorities, the lower bits of the priority register are truncated when defining priorities. This means that when configuring priority groupings, at least one bit must be reserved for subpriority, ensuring that even if all bits are dedicated to subpriority, no nesting will occur, only sequential processing. In the STM32 priority register, typically the upper 4 bits define the priority, but during grouping, the lower 4 bits may influence the grouping scheme, such as in Group 4 where all 4 bits are assigned to preemption priority, leaving none for subpriority.

The difference between "preemption priority" and "subpriority" can be understood as follows: If multiple interrupts happen at the same time, the CPU prioritizes based on preemption priority. New interrupts with a higher preemption level can preempt ongoing ones, leading to interrupt nesting. However, if interrupts have the same preemption priority, they are processed sequentially according to their subpriority, with the lowest subpriority being handled last. If both preemption and subpriority are identical, STM32 processes the interrupt with the lower vector address first.

Interrupts in STM32 can also be in a "pending" state, which occurs when an interrupt request is made but cannot be executed immediately due to an active interrupt with equal or higher preemption priority. The pending state can be manually set using the ISPR[2] (Interrupt Set-Pending Register) and cleared using the ICPR[2] (Interrupt Clear-Pending Register). When conditions allow, a pending interrupt will be processed based on its configured priority.

[midnightactual]

Cutting edge processors and all the latest and greatest additional computational hardware were fantastic assets to have when in environments where any malfunctioning or broken parts could be replaced more or less immediately.

Space was not one of those places. Being tens or hundreds of thousands of kilometers from the nearest resupply point wasn't a good place to have the fanciest gizmos going kaput with no spares on hand. This was on top of the considerations that anything you carried with you as backups meant less payload and more burnt fuel, and wherever you were going might not have whatever it was you needed for maintenance anyway if you didn't bring your own.

The driving logic behind designing dedicated space hardware, at least for manned use, had thus been quickly and firmly established as reliability first, maintainability second, and efficiency third. Putting it another way: nothing else mattered if you were dead; it was best that things could be readily fixed or at least replaced when possible, with a reasonable number of backups; and finally it was best if everything was as small, light, and energy efficient as possible given those prior two concerns.

As a result, hardware tended to have exactly the level of computational power and sophistication it needed, and nothing more. Parts were usually ruggedized, especially when they were milspec or for actual dedicated military applications, and accordingly could often seem downright primitive. While one might encounter distributed constellations of multiple redundant system-on-chips or microcontrollers around a cockpit or computer core in a spaceborne vehicle, in more peripheral areas one might find only simple rad-hard integrated circuit chips, merely transistor-transistor logic arrays, or (rarely) sometimes even just vacuum tubes.

Computational architecture thus often wasn't really so different from a biological nervous system in the end. Most of it was intended to be able to be repaired with the most rudimentary components and tools by even the most barely qualified personnel. Anyone could be trained to solder components into racked PCBs, and almost everyone who worked more than a service job in space was. Experience in assembly language programming, while less commonly mandatory, was also often de rigueur, with higher-level languages being optional. Mobile Suit pilots usually learned both necessities as part of their training curriculum. Whether they stayed any good at them or not was a different question.

Circumstances had forced Yoruichi to retain her skills at both. She wasn't an aerospace engineer, but she could diagnose and maintain, if not fix, just about any electronic or near-electronic hardware she encountered that could facilitate such repairs. She could also assemble her own rudimentary devices out of basic parts if necessary—and often had, from purpose-built hardware to simple drones.

Presently, she was slotting PCBs into a rudimentary case and hooking them together with cables, thereby apparently putting the finishing touches on some kind of basic, custom, purpose-built computer...

Methods of Implementing DC PLC Protocols

DC PLC communication mainly controls and monitors the condition of solar panels and energy storage systems. Additionally, DC PLC technologies are applied in industrial settings to supply power to electric motors and control them using a single pair of wires. All these applications suggest that the units responsible for communication over the power line are typically integrated into the corresponding devices (solar panel controllers, machines, and robots). Therefore, many automation system developers must understand how PLC protocols over DC power lines are implemented.

G3-PLC

The G3-PLC protocol is maintained by the international organization G3-Alliance.

Chipsets for this protocol generally comprise two microchips: an analog device for interfacing with the transmission line and a specialized microcontroller (SoC). In addition to signal processing, the microcontroller also handles encryption of the data transmitted over the line. The chipset may include a third chip responsible for converting the G3-PLC signal to one of the wireless protocols and back. Typically, this is the G3-Hybrid protocol designed for wireless networks to work alongside PLC. This protocol uses the 868 and 915 MHz frequency bands (which are not allowed for use in all countries).

This is an example of a G3-PLC chipset from STMicroelectronics: on the left is the microcontroller, and on the right is the analog interface chip.

The chipsets and their firmware must be certified by the G3-Alliance to bear the G3-PLC label. However, such certification does not negate the need to certify G3-PLC solutions with national communications authorities if required by local regulations.

At least three manufacturers of G3-PLC chipsets are known: Maxim Integrated (a division of the US-based Analog Devices), STMicroelectronics (a European company headquartered in the Netherlands), and Vertexcom Technologies (China).

PLC-Lite

The implementation of this protocol is governed by TI's internal documents. The TMS320F28035 universal signal processor is used for signal processing. In addition, the receiver and transmitter must include the AFE031 line interface chip. The chipset also includes execution devices LM34910 and TPS62170.

IEEE 2847-2021

At the time of writing, a South Korean startup was producing devices supporting IEEE 2847-2021 (HPDS-PLC); the protocol is used in an LED lighting controller and a servo drive. Information about the components used for their development is not publicly available.

Data Transmission from Vehicle Batteries Sensors

A new technology that optimizes electric vehicle charging based on the battery's parameters and its wear level. Wireless sensors are installed on the battery. The wires inside the vehicle through which the charging current flows act as antennas. The signal passes through the electric vehicle charging connector. It continues to propagate along the charging cable as a guided medium. This solves the problem caused by the inability of radio waves to pass through the vehicle's metal body. A transceiver is connected to the cable at the charging station.

This solution uses one of the wireless protocols from the IEEE 802.15.4 family. The most widespread and cost-effective in this family is the Zigbee protocol. Therefore, it makes sense to use a chipset specifically for this protocol. Zigbee uses the 2.4 GHz band, and the frequency data transmission occurs along the charging station's cable. It should be noted that this solution is only possible for DC charging because, in this mode, the wires from the charging connector go directly to the battery.

Is software implementation of PLC algorithms possible?

For G3-PLC, using a general-purpose processor instead of a specialized microcontroller would require more chips than just two. Large production volumes and significant market competition produce relatively low prices for G3-PLC chipsets. These chips are manufactured across different regions—America, Europe, and Asia—ensuring a diversified supply. Therefore, developing a custom G3-PLC solution using general-purpose chips is not economically viable.

In PLC-Lite, a different company's signal processor can be used instead of TI's. However, new firmware would need to be written for it, which is quite costly. The TMS320F28035 is well protected from reverse engineering, so third parties cannot read the firmware stored in its memory.

No specialized chips are being produced yet for the IEEE 2847-2021 protocol, so its signal-processing algorithms must be implemented through the software on general-purpose microcontrollers.

It is more cost-effective to use specialized chips for creating PLC solutions.

The Zigbee protocol is implemented with a single chip that includes a microcontroller and a transceiver operating in the 2.4 GHz band. Using a general-purpose microcontroller would require a separate radio module, and interfacing these two units would be a highly complex task.

In conclusion, specialized chipsets are more cost-effective for PLC systems (except those using the IEEE 2847-2021 protocol).
