Pladask Elektrisk - ReFORM

"ReFORM is an experimental multi-effects processor featuring 24 algorithms focusing on granular synthesis and modified sample playback. Among its algorithms you’ll find granular time stretching, pitch shifting time stretching, freeze and shuffling effects, glitching sample playback and a beat repeater. It´s built around the Spin FV-1 digital signal processor (DSP). The pedal is made up of a DSP core, a “wrapper” consisting of an analog dry/wet mixer with various parameters and two mappable expression functions for overriding its three digital parameter knobs. ReFORM is also a programmable effect pedal. There is an empty EEPROM-slot for your own programs (8)."

Robot girl, finally back online after a year and a half, looking at the newly outfitted soldering station. There's a lot more tools on it than there were when she last closed her eyes: Inspection microscopes, hot air reflow, EEPROM programmers, logic analyzers, thermal cameras and regulated power supplies. She starts to tear up when she sees the video history of her partner (and repairperson): months and months of electronic tutorials, starting simple ("what is a circuit?") and towards the end there's PCB design classes and CCC videos about reverse engineering secure processor firmware.

"You did all this, for me?" she asks, her voice sounding different from how she remembers it, lacking the stutterglitch and 8-bit audio harshness. Her partner smiles. "I thought I'd lost you... I couldn't live with that. I had to!"

She hugs them in a pile of spare parts, servos moving smoothly for the first time in decades, pressure sensors finally accurate enough to hold them without risk of crushing them.

Sometimes, love is stored in the soldering iron.

Stepping Backwards a Bit (or 24)

I was looking for a simpler project. My recent 68030 work has been challenging and really pushing the limits of what I can do. I wanted something I could work on, but perhaps where someone else has already worked out the hardest parts.

I find laying out PCBs to be rather relaxing. It's one of those repetitive, almost meditative tasks, like needlepoint or whittling. The kind of hobby where I can turn on some music or a comfortable old TV show, zone out for a few hours, and wake up to this new thing that I created.

Debugging however is very mentally taxing, and the design work required to have a functional schematic to create a PCB for is an active whole-mind prices. So what I really needed was an existing project I could design a board for.

Enter [Grant Searle]. If you're not familiar with [Grant Searle], he has excellent designs for breadboard computers with a very minimal parts count. I studied his minimal Z80 design when I was first starting to build my own computers and learned a lot from it. I highly recommend his work for anyone who is interested in learning how to build their own computer but doesn't know where to start.

I was recently given a Rockwell 6502 CPU pulled from a dead LED marquee. I've never actually worked with 6502, so this seemed like a good time to try building Grant's 8-chip (or 7-chip) 6502 computer.

A few hours later, I had a PCB design completed, gerbers generated, and an order placed. Less than $5 for 5 boards, including shipping. A couple weeks later they arrived in the mail.

I did end up making a few modifications to [Grant]'s design. Instead of a clock circuit made from a discrete crystal and a couple inverter gates, I used a TTL oscillator because I've always found them to be more reliable. I also added support for an FTDI USB Serial adapter chip so that the board can be used with a modern computer as a terminal. And finally, since a PCB is much harder to add new components to relative to a solderless breadboard, I added an expansion header. All of it wrapped up in a compact PCB with lots of helpful silkscreen marking.

I realized after I had ordered the PCBs that the 16kB ROM chips [Grant] used are no longer manufactured or readily available. I have plenty of 8kB EEPROM chips on hand however. Thankfully the OSI BASIC interpreter [Grant] ported to this design fits within 8kB, so I was able to make a few adjustments and re-assemble it to work with the ROM chips I have on hand.

After a small glitch with my EEPROM programmer, it works!

It's quite a change going from my 33MHz+ 68030 to this tiny 6502 running at just under 2MHz. The BASIC text-based Mandelbrot renderer that completes in seconds on my 68030 takes four and a half minutes on the 6502. Not bad at all, considering my bus-impaired 68000 build takes 9 minutes to do the same.

This was a fun little project. It was a nice little break from some of the more difficult projects I've been working on. I have shared the project on GitHub for anyone who might want to take a look.

I hope to have this project with me this weekend, June 14-16, 2024 at Vintage Computer Festival Southwest. I'll be at table 207 in the Tandy Assemble hall, just across the street from the main exhibit hall.

EEP ROM is some masterful typography. It's cute and technically accurate!

See at first we had mask ROMs: this is where you have a chip that's designed from the start to only have some specific data on it. That's why it's Read Only Memory: it's memory, but you can only read it. This is what, like, NES games were built on: the game is on the ROM chip, and can't be changed.

Then someone figured out you could make the chip so that it starts out blank, then you can program it once (like burning a CD-R), so we called these Programmable ROMs: PROMs.

And then another clever engineer worked out how to make them re-erasable, by using ultraviolet light that causes the bits to weaken. You have to take out the chip, expose it in a special box (you can't just have a flashlight, because UV light will give you skin cancer and sunburns on your eyes), then program it and put it back in. But hey, it's erasable and reusable now! This is how a lot of games were developed for cartridge consoles: you'd have a special cartridge that has exposed chips, which you program and put back in the console to test. This new erasable and programmable ROM was obviously called the Erasable Programmable ROM, or an EPROM.

But then a very clever trick was figured out: if you use quantum mechanical effects you can trap charge in a tiny cell and get it out using quantum tunneling, which means you can erase it in-situ! Now you have a reusable (for a while) rewritable chip, so it was called Electrically Erasable Programmable Read Only Memory: EEPROM!

But by putting a space in it, they made it an EEP ROM, which is a much cuter name.

BTW EEPROMs are what flash memory grew out of: this is a 1985 SD card.

A Comprehensive Guide to Firmware Development

In the world of embedded systems and smart devices, firmware plays a critical role in enabling hardware to function effectively. Whether you're developing IoT devices, automotive systems, or industrial machinery, firmware development is the backbone that bridges hardware and software.

In this blog post, we’ll explore what firmware is, its importance, the development process, tools used, and best practices to ensure efficient and secure firmware solutions.

What is Firmware?

Firmware is a specialized type of software that provides low-level control for a device's specific hardware. Unlike regular software applications, firmware is tightly coupled with the hardware and is often stored in non-volatile memory such as ROM, EEPROM, or flash memory.

Examples of devices with firmware include:

Smartphones

Routers

Smart TVs

Medical devices

Automotive control units (ECUs)

Why is Firmware Important?

Firmware is essential because it:

Controls hardware operations: Without firmware, the hardware components of a device would be non-functional.

Ensures device functionality: It manages startup routines, I/O operations, sensor integration, and communication protocols.

Supports software-hardware integration: Firmware acts as a middle layer, allowing high-level software applications to interact with low-level hardware components.

Enables updates: Firmware can often be updated to fix bugs, enhance performance, or add features.

The Firmware Development Process

1. Requirements Gathering

Understanding the hardware specifications and the device’s purpose is crucial. Developers need to gather requirements from both hardware engineers and end users.

2. Architecture Design

This involves deciding on the architecture and communication protocols (e.g., I2C, SPI, UART), memory usage, and timing constraints.

3. Choosing a Development Platform

Most firmware is written in C or C++ due to their efficiency and hardware-level access. You’ll also need:

Microcontroller/microprocessor datasheets

Board Support Packages (BSPs)

RTOS (Real-Time Operating System), if required

4. Coding and Integration

Firmware code is written to interface directly with hardware. This includes writing drivers for peripherals (LEDs, sensors, motors) and managing power consumption, timing, and interrupts.

5. Testing and Debugging

Testing includes:

Unit testing

Hardware-in-the-loop (HIL) testing

Simulation and emulation tools

Debugging tools such as JTAG and SWD are used to step through code and analyze performance.

6. Deployment

Once tested, firmware is compiled and flashed onto the device using programmers or over-the-air (OTA) update mechanisms.

Tools Used in Firmware Development

Integrated Development Environments (IDEs): Keil µVision, MPLAB X, STM32CubeIDE

Compilers and Toolchains: GCC, IAR Embedded Workbench

Debuggers/Programmers: JTAG, ST-LINK, AVR ISP

Version Control Systems: Git

Simulators/Emulators: QEMU, Proteus

Best Practices for Firmware Development

Write modular and reusable code

Follow coding standards (e.g., MISRA C for safety-critical systems)

Optimize for memory and power consumption

Document thoroughly for maintainability

Implement fail-safes and watchdog timers

Secure your firmware (e.g., with encryption and secure boot loaders)

Plan for firmware updates with mechanisms like OTA updates
