Re: Any inline assembler tutorial?
I've written assembler, but try to avoid it if I can. If what you want is optimizing c source, what I do is compile with the '-S' option.

Home directory on usb external disk recommended; home directory con internal sdcard can be painfully slow. I'm using this for a small blue pill project. No 32bit version. sorry. https://github.com/koen...

semihosting and serialwireoutput
Two libraries, handy when debugging an stm32duino: With Serial Wire Output (SWO) an stm32duino can write tracing and logging to a pc at high speed. With semihosting an stm32duino can do keyboard input, screen output, and file I/O on the pc where the debugger is running. For these libraries to work, ...
