#stm32

Second iteration is assembled! Definitely some more work to be done to sort out UCPD issues. I am still wrapping my head around the CC and CCDB pins. Some preliminary bodges show promise. I think we will be able to start working on the software with @dragonmux soon after the bmputil V1.0 and Black Magic Debug V2.0 release. :D (DISCLAIMER: this is a long term project, don't hold your breath. If you need a BMP get the V2.3) #electronics #debugging #jtag #swd #mcu #stm32

@thebootloader just having a listen, there is a board package called STM32Duino for the Arduino ecosystem

Also, STM do have reference manuals for the HAL/LL APIs, I’ve downloaded them for several families, despite hating Cube with a passion

I generally dump HAL in favour of LibOpenCM3, and have coded synth oscillators, envelopes, and SVGA monochrome that barely needs any CPU time using these API’s

@oshpark boards in today! This is a USB/CAN-FD adapter, to start working on CAN-FD support in #zencan. It's an stm32g0 + TCAN1044.

I'm also considering standardizing on these JST XH connectors for CAN stuff, mainly b/c they have these right angle board-to-board plgus to make PCB "T"s or terminators. The friction fit is pretty good? But I'm a little worried about wiggling loose over time in a vehicle. Interested in other connector suggestions for this...

I am ALL for #AI and #Claude and #GPT, etc. I do however, in my free time outside of work, school and creating STEM tutorials to help the next generation, believe that spending time in pure #Assembler in a bare-metal #Embedded #microcontroller will help you understand #Computer #Science in a way that can help you drive the future in #technology. I have and will continue to post pure Assembler drivers to help others achieve this utilizing #Arduino and #STM32 products.

Updated my STM32 KiCad Symbol generator! It now generates the modern library format and uses alternate pin functions feature. I decided not to include the "all features listed" strings as I did in the past. (I might add them later as a dedicated alternate function.) This results in more compact symbols. Because it is my personal preference I keep the GPIO pin name in every alt-function. Give it a try, let me know what you think. #kicad #stm32 #opensource #mcu github.com/esden/stm32-kicad-l

Btw. Here's another 6½min live performance from my talk @ #Resonate 2016. Alas, there were some cable issues on stage and I had to record it all afterwards in my hotel room. The setup was the same as in the first video from the previous post (i.e. STM32F746 DISCO + Korg Nanokontrol)

Just realised the readme for thi.ng/synstack (a C11 & Forth-based softsynth engine for #STM32) had broken links to two live performances/demos I creeated in early 2016. I've now fixed those and re-uploaded these videos to my Makertube/Peertube:
