We're vibin' with Claude 3.7 and writing uBlox drivers 😎🤖🛰️

Heeeey, we're just having a super chill vibe here at the desk of Ladyada—writing a driver for the uBlox M8Q

https://blog.adafruit.com/2024/09/10/a-mini-gps-from-ublox-with-i2c-and-uart

, which has both I2C and UART interfaces. As expected, it can do everyday NMEA output, but it can also do UBX, a "compressed" protocol for advanced data reads and writes over I2C/UART—or even SPI on some other chips.

However, the UBX protocol is a hugely complex driver to implement, with dozens of commands and hundreds of flags. But why stress when you can viiiibe? We're using this beast of a spec as an excuse to try out the new Claude 3.7, which is doing great at chomping through the UBX documentation roughage and giving us some nice code on the other side. Within an hour, we're able to connect and switch to UBX mode by sending a well-formed message and receiving an ACK.

What we like about coding with a good LLM is that it does the work we sometimes get lazy over, like handling various error conditions, timeouts, and verbose error messages.

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.

Why India’s Drone Industry Needs Periplex: The Hardware Tool Drones Didn’t Know They Needed

As drones fly deeper into critical roles — from agricultural intelligence to autonomous mapping, from disaster response to military ops — the hardware stack that powers them is undergoing a silent revolution.

At the center of that transformation is Periplex — a breakthrough tool from Vicharak’s Vaaman platform that redefines how drone builders can interface with the real world.

What is Periplex?

Periplex is a hardware-generation engine. It converts JSON descriptions like this:{ "uart": [ { "id": 0, "TX": "GPIOT_RXP28", "RX": "GPIOT_RXN28" } ], "i2c": [ { "id": 3, "SCL": "GPIOT_RXP27", "SDA": "GPIOT_RXP24" }, { "id": 4, "SCL": "GPIOL_63", "SDA": "GPIOT_RXN24" } ], "gpio": [], "pwm": [], "ws": [], "spi": [], "onewire": [], "can": [], "i2s": [] }

…into live hardware interfaces, directly embedded into Vaaman’s FPGA fabric. It auto-generates the FPGA logic, maps it to kernel-level drivers, and exposes them to Linux.

Think of it as the “React.js of peripherals” — make a change, and the hardware updates.

Real Drone Applications That Truly Need Periplex

Let’s break this down with actual field-grade drone use cases where traditional microcontrollers choke, and Periplex thrives.

1. Multi-Peripheral High-Speed Data Collection for Precision Agriculture

Scenario: A drone is scanning fields for crop health with:

2 multispectral cameras (I2C/SPI)

GPS + RTK module (2x UART)

Wind sensor (I2C)

Sprayer flow monitor (PWM feedback loop)

ESCs for 8 motors (PWM)

1 CAN-based fertilizer module

The Periplex Edge: Microcontrollers would require multiple chips or muxing tricks, causing delays and bottlenecks. With Periplex:

You just declare all interfaces in a JSON file.

It builds the required logic and exposes /dev/pwm0, /dev/can0, etc.

Zero code, zero hassle, zero hardware redesign.

2. Swarm Communication and Custom Protocol Stacks

Scenario: Swarm drones communicate over:

RF LoRa (custom SPI/UART)

UWB mesh (proprietary protocol)

Redundant backup over CAN

Periplex lets you:

Create hybrid protocol stacks

Embed real-time hardware timers, parity logic, and custom UART framing — none of which are feasible in most MCUs

Replacing Microcontrollers, Not Just Augmenting Them

| Feature | Microcontroller | Periplex on Vaaman | |---------------------------|----------------------------|------------------------------------| | Number of peripherals | Limited (4–6) | Virtually unlimited (30+ possible) | | Reconfiguration time | Flash + reboot | Real-time, dynamic reload | | Timing precision | Software-timer limited | FPGA-grade nanosecond-level timing | | AI compatibility | Not feasible | Integrated (Gati Engine) | | Sensor fusion performance | Bottlenecked | Parallel FPGA pipelines |

Developers Love JSON, Not Register Maps

No more:

Scouring 400-page datasheets

Bitmasking registers for I2C configs

Writing interrupt handlers from scratch

Just declare what you need. Let Periplex do the work. Peripherals become software-defined, but hardware-implemented.

Built in India, for India’s Drone Revolution

Vaaman + Periplex isn’t just about tech. It’s about self-reliance.

India’s defence, agriculture, and logistics sectors need secure, reconfigurable, audit-friendly hardware — not black-box SoCs from questionable supply chains.

Periplex is the hardware engine for Atmanirbhar Bharat in drones.

TL;DR

Periplex lets drones adapt hardware to the mission — instantly.

It replaces tangled microcontroller logic with clean, structured JSON.

It unlocks use cases microcontrollers can’t touch: AI at the edge, dynamic reconfiguration, secure protocol stacks, and more.

And it’s built into Vaaman, India’s first reconfigurable edge computer.

Exploring How the Speed of China DC Brushed Motor Can Be Effectively Controlled

The China DC Brushed Motor remains a widely used electromechanical component in various industries due to its cost-effectiveness, simplicity, and reliability. From small household appliances to industrial machines, these motors offer a straightforward solution for motion control. A critical aspect of their functionality lies in speed regulation. Whether for precision devices or variable-speed tools, controlling motor speed efficiently is essential. This article delves into the common methods used to manage the speed of a China DC Brushed Motor and how each technique impacts performance.

Voltage Control Method

One of the basic and direct ways to adjust the speed of a DC brushed motor is by varying the applied voltage. Since motor speed is nearly proportional to the supply voltage, increasing the voltage results in a higher rotational speed, while decreasing it slows the motor down. This method is simple and effective, especially in low-cost systems. However, it offers limited precision and may affect torque output and efficiency at lower voltages. Additionally, voltage drops under load can cause speed instability, making this approach less suitable for applications requiring consistent performance.

Pulse Width Modulation (PWM)

PWM is the commonly used method for precise speed control in a China DC Brushed Motor. Instead of reducing voltage directly, this technique turns the power on and off rapidly using electronic switches. By adjusting the duty cycle—the proportion of time the power is "on" during each cycle—PWM effectively controls the average voltage supplied to the motor. This allows for highly efficient speed modulation without significant power loss or heat generation. PWM also enables smoother acceleration and deceleration and is widely supported by microcontrollers and motor drivers, making it ideal for modern automation systems.

Closed-Loop Feedback Control

For applications where stable and accurate speed is critical, closed-loop systems are used. These systems integrate sensors, such as encoders or tachometers, that continuously monitor the motor’s speed and provide real-time feedback to a controller. The controller compares the actual speed to the desired value and adjusts the input (often via PWM) accordingly. This setup compensates for load changes or supply fluctuations and ensures consistent performance. Though more complex and costly, closed-loop control offers high precision and is frequently employed in robotics, CNC machines, and other demanding environments using China DC Brushed Motors.

Resistive Speed Control (Less Common Today)

In the past, series resistors were often used to drop voltage and thereby reduce motor speed. While still occasionally seen in low-tech or educational applications, this method is inefficient, as the resistor dissipates energy as heat. It also causes voltage instability under load and provides poor control resolution. As such, resistive methods are now largely obsolete compared to PWM and electronic controllers.

Digital Motor Controllers

Modern digital controllers bring together advanced techniques for controlling China DC Brushed Motors. These systems often combine PWM modulation, feedback loops, and interface options for programmable speed settings. Some even support communication protocols like CAN, UART, or I²C, allowing for integration into larger embedded systems. These controllers not only enhance speed control accuracy but also improve safety, protection, and diagnostics.

Conclusion

Controlling the speed of a China DC Brushed Motor involves a range of techniques, from simple voltage adjustments to advanced PWM and closed-loop systems. Each method has its strengths and trade-offs, with the choice depending on application requirements such as cost, precision, and energy efficiency. As technology evolves, smarter and more integrated control systems continue to expand the versatility of these reliable motors, ensuring their relevance across both traditional and modern industries.

Performance Highlights: Output Speed and Torque: The motor offers a versatile range of speed and torque options, allowing for customization to suit specific application requirements. The gearbox provides precise control over speed and torque output. Efficiency: With its brushed DC technology and precision gearbox, this motor delivers high efficiency, minimizing energy consumption and heat generation. Reliability: The 7712Z motor is designed for continuous operation with minimal wear and tear, ensuring a reliable performance over an extended lifespan.

What are interrupts used for mainly?

In embedded systems, interrupts are a crucial mechanism that allows a processor to respond immediately to important events, even while executing other tasks. Instead of continuously checking (or polling) for events like button presses, sensor data, or communication input, an interrupt automatically notifies the processor when an event occurs, allowing for faster and more efficient operation.

Interrupts essentially "interrupt" the normal execution flow of a program to handle urgent tasks. This is done using an Interrupt Service Routine (ISR) — a special function that is executed in response to the interrupt. Once the ISR finishes, the processor resumes its previous task. This ability to react instantly is vital in real-time applications, such as reading data from sensors, responding to user input, or handling communication protocols like UART, SPI, or I2C.

There are two main types of interrupts: hardware and software. Hardware interrupts are triggered by peripherals or external devices (like a temperature sensor), while software interrupts are triggered by programs to signal specific events internally.

Using interrupts helps optimize CPU usage, reduce power consumption (as the CPU can sleep until interrupted), and ensure timely responses to critical events. However, poor interrupt handling can lead to issues like missed events or system crashes, so proper design and prioritization of interrupts are essential.

Overall, interrupts form the backbone of responsiveness in modern embedded systems and are indispensable for designing efficient, real-time applications. For those aspiring to build a career in this domain, mastering interrupt-driven programming is a key skill. A structured embedded systems course with placement can provide hands-on experience and career opportunities in this high-demand field.

Embedded Systems Course in Pune with Placement

If you’re in Pune and serious about a career in embedded systems or IoT, there’s a good chance you’ve heard the name Technoscripts. Since 2007, this institute has helped thousands of students and professionals move beyond theory and into real embedded jobs. Whether you’re a fresher aiming to break into the core electronics field or someone looking to switch domains, Technoscripts has built a reputation for being one of the most reliable places to start that journey.

Let’s take a closer look at what makes this place different — and why so many students recommend it.

A Strong Foundation in Embedded Systems Training

Technoscripts didn’t just pop up recently. It’s been around for over 18 years, which means they’ve seen the industry change and evolve — and they’ve updated their training along with it. From basic microcontroller programming to more advanced topics like RTOS, device drivers, and IoT, their curriculum is built to match what companies are actually looking for.

The institute runs its classes in Shivaji Nagar, Pune, and offers both online and offline batches. So whether you’re a college student, a working professional, or someone in between, you can find a batch that fits your schedule.

Learning by Doing — The Practical Approach

One of the biggest reasons students choose Technoscripts is the hands-on learning. Here, you won’t just be sitting through theory lectures. You’ll get your hands dirty — working with sensors, microcontrollers, and various protocols like UART and I2C.

Each course includes at least two live projects, which gives you actual project experience. These aren’t just dummy projects either — they’re built to mimic what engineers work on in the real world. That experience becomes a big plus when you start applying for jobs.

And because the batches are small, you get personal attention. Trainers are not just teaching from slides — they’ve worked in the industry and know how things really work. Students often say the trainers are supportive, clear with concepts, and genuinely interested in helping you learn.

Course Options That Fit Different Goals

Whether you’re just starting out or looking to specialize, Technoscripts has courses for every level.

Embedded Systems Course in Pune with Placement — This is their flagship course. It runs for about 4 months and covers everything from C programming and 8051 microcontrollers to ARM, PIC, and wireless technologies. It’s designed to get you job-ready.

IoT Training — One of the first IoT-focused courses in India, this one teaches you how to build smart, connected devices. It’s ideal if you want to get into future-focused tech.

Automotive Embedded, MATLAB, and AUTOSAR — These are great if you’re targeting specific sectors or want to move into niche roles.

Post Graduate Diploma in Embedded Systems — Perfect for beginners, this course gives you a solid foundation and gradually builds up your skills with lab-based learning.

Solid Placement Support That Actually Works

A lot of institutes say they offer placements. Technoscripts actually delivers. Their placement team is active, always coordinating interviews, helping with resumes, and preparing students with mock interviews and soft skills sessions.

They have ties with several companies, from big MNCs to core embedded startups. That means more chances for students to land roles that actually match their training. You’ll find Technoscripts students placed in companies working on automotive, medical, and industrial applications.

The feedback is consistent — students who put in the effort get placed.

“I got placed in Spark as an Embedded Developer. The training was hands-on and the support from the placement team was excellent,” says one student.

“Technoscripts is the best training institute in Pune. I got placed in a good company and learned so much through practical projects,” says another.

Industry Exposure and Certifications That Matter

Technoscripts doesn’t operate in a vacuum. They keep their training relevant by partnering with companies, organizing guest lectures, and even arranging internships and industry visits.

They also provide NASSCOM®-certified training, which adds weight to your resume and helps during hiring processes.

Their courses are regularly updated to include trending technologies like STM32 microcontrollers, Embedded Linux, and IoT protocols, so you’re not learning outdated stuff.

Flexible Learning Options for All Schedules

Not everyone has the same timetable. That’s why Technoscripts offers:

Regular batches

Fast-track programs

Weekend classes

Early morning & evening options

Live online training with project kits

Even if you’re working full-time, you can still attend and learn at your pace.

A Supportive, Student-First Atmosphere

Beyond the tech and tools, what really makes Technoscripts stand out is its student-friendly environment. The faculty is approachable, and the vibe is encouraging. They even host webinars, meetups, and project expos to keep the energy going.

One student said it best:

“The atmosphere here is very healthy. There are regular live projects, webinars, and opportunities to apply what you learn.”

A Few Areas to Improve — And They’re Listening

Like any place, Technoscripts isn’t perfect. Some students have said they’d like even more extracurricular activities or career-focused workshops. The good part? The institute listens. They’ve been adding more events and soft skills sessions over time to give students a well-rounded experience.

Final Thoughts

Technoscripts Embedded Institute isn’t just about teaching you how to blink an LED. It’s about building a career in embedded systems, step by step — with practical skills, real projects, and strong placement backing.

Whether you’re looking for your first core job, planning to switch domains, or just want to build something real, Technoscripts can be your launchpad.

If you’re serious about embedded systems, this is a great place to start.

E5908 module RJ45 interface communication

How to achieve communication with the E5908 module RJ45, a brief introduction to help you take the next step

Introduction to the module and interface E5908 is an Ethernet communication module with a built-in TCP/IP protocol stack. It supports direct communication with an Ethernet switch or router through the RJ45 interface. The main control MCU can interact with the module through UART (AT command) or SPI/SDIO (depending on the module description).

Hardware connection (RJ45 interface) RJ45 interface (with magnetic transformer): The module's onboard RJ45 interface has an integrated magnetic transformer and can be plugged into a standard network cable without an external transformer. Power and ground: VCC (3.3V/5V) -> module VCC, GND -> module GND. UART connection: MCU_TX -> module UART_RX, MCU_RX -> module UART_TX Reset pin: connected to the MCU GPIO for module hardware reset. Decoupling capacitors: Add 10µF and 0.1µF decoupling capacitors to the module power pins to ensure stable power supply.

Network configuration:

DHCP: AT+NETMODE=DHCP returns +IP:...; Static IP: AT+NETMODE=STATIC,<IP>,<Mask>,<Gateway>. Establish socket: TCP client: AT+TCPSTART="<IP>",<Port>; TCP server: AT+TCPLISTEN=<Port>; UDP: AT+UDPSTART="<IP>",<Port>.

Data sending and receiving: Sending: AT+TCPSEND=<Len> → module prompts > → sending data; Receiving: module serial port pushes +TCP:RECV,..., followed by data.

Typical C code example:

#define UARThuart1 bool at_send(const char *cmd, const char *exp, uint32_t to) {...} void net_init(void) { //reset HAL_GPIO_WritePin(RESET_GPIO_Port, RESET_Pin, GPIO_PIN_RESET); HAL_Delay(50); HAL_GPIO_WritePin(RESET_GPIO_Port, RESET_Pin, GPIO_PIN_SET); HAL_Delay(200); at_send("AT+NETMODE=DHCP", "OK", 2000); } void tcp_client(void) { at_send("AT+TCPSTART=\"192.168.1.50\",8000", "CONNECT", 5000); at_send("AT+TCPSEND=5", ">", 2000); HAL_UART_Transmit(&UART, (uint8_t*)"hello", 5, 100); at_send("", "SENDOK", 2000); at_send("AT+TCPSTOP", "CLOSED", 3000); }
