I am happy to announce the FemtoMSP430, a processor designed with the instruction set of the classic #MSP430, but with a flexible bus interface similar to @BrunoLevy01 #FemtoRV32 including memory busy signaling. The playground contains a phantasy "microcontroller" design for the #ULX3S #FPGA board, interactively running the original #Mecrisp #Forth image for MSP430G2755, enhanced with a text mode on 800x600 video, USB-CDC terminal and a lot of GPIO wires: https://codeberg.org/Mecrisp/FemtoMSP430

If you've ever played around with TI microcontrollers, you've probably had to use the Code Composer Studio, which is fine and all, but I found out recently they made their own open source C compiler.
It's nice to know that they not only have a compiler I can use (meaning I'm not locked into using an IDE), but that it's also on the AUR!

Зачем программисту дизассемблер в 2025: отладка на слепую под редкие MCU
Даже в 2025 году, когда вокруг нейросети, автогенерация кода и IDE с предиктивным интеллектом, работа с редкими микроконтроллерами всё ещё может обернуться настоящим хардкором. Особенно, если речь идёт о «слепой» отладке без отладчика, когда в арсенале только прошивка, HEX-файл и пара байтов на выводе. В этой статье — личный опыт, много хардкора, дизассемблирование вручную и поиск глюка в 2 КБ бинаря. Когда говорят «отладка», в 2025 году чаще всего имеют в виду жмяк на F5 в Visual Studio Code или лог с CI/CD. Но в embedded-мире, особенно если ты копаешься в системах с 8-битным контроллером 2006 года выпуска, это слово может означать кое-что пострашнее. Например — «прошивка вылетает на 4-й секунде, данных в UART нет, отладочного интерфейса нет, документации почти нет, а заказчик просит сделать "как раньше работало"». И вот тут начинается старый добрый reverse engineering.

I got the #MSP430 #MCU boards cheap, $4.30 for boards with debuggers, got a handful of MSP430F2553s. They're kind-of the go-to for noodling around on a protoboard when I want a debugger, but the peripherals are clearly designed by people that don't write code! I don't care they're 16-bit or kind-of-like a PDP-11, they're just another MCU programmed in C

#introduction
This should be my last introduction toot! I mentioned my professional focus (#neuroimaging #neuroscience signal analysis) in my last toot. Now, for my other non-research engagements...I am a #maker who uses tools like #programming #arduino #msp430 #raspberrypi #electronics and #3dprinting to prototype fun projects. I have my own fleet of 3d printers and support equipment.
As a signal processing engineer, I'm also very interested in #sdr (software-defined radio). I'm working on two pet projects right now employing SDR and my maker tools for backyard #radio #astronomy and satellite signal reception. While not entirely novel end-goals, the work is very engaging and rewarding! I hope to package the results for science outreach in #steam in the near future.
Everyone should expect neuroimaging research toots from me as well as updates on my projects and resources for #STEM and #STEAM engagement in the classroom. I hope to contribute to #edutoot by sharing my demos, resources, and projects for bringing innovative thinking, science, and engineering into the classroom.
I love #biking and outdoor activities. I'm a novice in #photograpy (microscope as well as DSLR) and am looking for hints and suggestions for my entry into #astrophotography . Any advice? Let me know! I have a strong love of #fish and #aquariums, so expect my gushing about fish on occasion. I also have a pet parakeet, so expect some bird antics along the way! It can't all be work and seriousness, after all!

@don_kosak Ever do any #MSP430 embedded programming? I heard it has a very similar instruction set to the PDP-11.

#TIL TI MSP430 CPU's instruction set is basically "what if we redesign the PDP-11, but more RISC-like."
Wow, I spent a month on PDP-11 assembly this year, who knows it has practical applications?! Shut up and take my money? #electronics #retrocomputing #PDP11 #MSP430
