Arduino for STM32

I see this board presents challenges. With v1.9.0 core, Blink sketch and upload via J-Link SWD I have problems with board immediately losing the SWD connection and I am unable to debug. After that I am unable to connect to the board over SWD with or without hardware reset. I have to fully erase the ...

Hi flof, Pretty hard to say without a better understanding of your setup. Could you post a pic or diagram of your setup and how exactly you are testing? CAN bus hello world can be a big first step. Either everything is hooked up right and it just works or its not and you get nothing. I've found that...

It turns out I was looking at a NUCLEO-F072RB variant as well. I want to make use of the USB Full-speed device (crystal-less) feature. The mapping is indeed different than the Disco F072RB board. Follwing the wiki directions (https://github.com/stm32duino/wiki/wiki/Add-a-new-variant-%28board%29), I ...

The stino project looks to have been inactive for some time.

I've now combined the F103 and F303 examples into a single example with #ifdefs to cover the deltas between those two processors, moved from my DWT library to builtin delayMicroseconds() and cleaned up the CAN/GPIO peripheral init routines. I've successfully retested on F103 and F303, and am conside...

About DWT, note that the core is already based on it for delayMicroseconds() arduino API

Ah thanks. Not sure how I missed that. I will migrate over to core delayMicroseconds() in place of my library implementation.

The below url's are broken in your post: I like your delay routine, using the cyclecounter :) Where does : #include " stm32_def.h " come from ?? - the Arduino libs or some local stuff ?? Thanks. I fixed the broken links above. I borrowed the DWT based delay from the contributions of other...

F303CC test pictorial schematic:

I've now completed testing of the F103C8 and F303CC UAVCAN based CAN examples in the repo, so now consider the repo to be up to date for v1.8 of core. I've used a Robotdyn F303CC black pill (https://robotdyn.com/stm32f303cct6-256-kb-flash-stm32-arm-cortexr-m4-mini-system-dev-board-3326a9dd-3c19-11e9...

F103 Bluepill end-to-end CAN testing now complete. ESC values input with UAVCAN GUI are sent over CAN bus to Bluepill node, which receives and retransmits those same ESC values out over Serial. Below is a screen-cap. You can just make out the ESC input values in the "ESC Management Panel" ...
