STM32F3 ports

[romeo]

Yes! It seems to be different from STM32F091 also...
Probably I'll have to find a book for getting around this kind of issues ...
Nothing I used to know seems to look like c language used in here!
Is there any porting guide for uPy? Google didn't help with this either.

Thank you!

The Reference Manuals for the chips in question will be your goto for information.

Hi!

Managed to pass by powerctrl.c compilation.
File timer.c is next.
Probably reference manual will contain a solution!

Current status is on github.

Hi!

I was reading through documentation and I fail to solve this step:

Code: Select all

make: *** [build-STM32F3DISC/timer.o] Error 1

Any idea?
Thanks,

Hi! Solved the timer, stuck on dma!

Any help is welcome !

[romeo]

Hi!
Does anybody know if the SPI DMA mechanism on STM32F3 is similar to F0 or F4? I can't figure it out! Thanks!

[romeo]

Hi everyone!

I finally compiled successfully (without I2C and SPI now, since the mechanism is quite different from both F0 and F4).

If anyone has the ability to help out with this, I will try an update.

Best regards,
Romeo
