Arduino for STM32

I still have some test work to do on the F1 serial output and test of F3 variant before I will consider the example up to date, but F1 CAN traffic appears to be working as expected. I'll update here once I get a chance to complete testing. For those looking to replicate, it is worth mentioning that ...

Here is a "Hello World" example working for libcanard based UAVCAN on Arduino_Core_STM32. I've documented the work here to remember what I did and so that others can follow if so desired. I'm a big fan of Pavel Kirienko's open UAVCAN work (https://uavcan.org/) for my needs, mostly UAVs and...

You can find RAM size in the variant linker scripts, in boards.txt (https://github.com/stm32duino/Arduino_C ... boards.txt), and also in the part datasheet for your given processor.

Finally, when you compile you get a percentage of dynamic memory used in the console pane.

STM32 GPIO is a bit more flexible and complicated than AVR. You should definitely scan through the AN4899 application note above to get a feel for the differences. There are ways to write to whole port registers once you understand what you want to do. You can use the C/C++ arrow operator -> to acce...

Ok sounds good. I get that keeping it smaller helps on bandwidth. But the world is moving in the direction of more visual content to share information and learning so I guess it is a balance. In actual use cases here I am finding that 96K is on the small side for partial screen captures. Maybe 50% a...

Hi,

Congrats on re-opening the forum, thank you for the efforts.

I've created a first post and attempted to upload a couple of images. Is there a file size restriction for attachments, and if so what is that limit?

Thanks,

STM32F405RG can be found on many F4 based drone flight controllers. https://oscarliang.com/f1-f3-f4-flight-controller/ So I found myself wishing I had an F405 based Nucleo board for development. Somehow ST never came out with a F405 Nucleo board, so I went and reworked a Nucleo-F103RB into one. I sw...
