ChibiOS Free Embedded RTOS

Hello,
by looking at the example board config (olimex p107), I can see that spi miso and mosi are configured as follows:



however, when looking in testhal/STM32F1xx/SPI/main.c I see the following commands:



I'm using the 2.6.1 release. Can you please clarify which config is correct? I suppose the one with digital input, but I would rather have it confirmed.

HI,

The one with digital input is correct, it is possible that the one with alternate is working too, I have to verify.

Hey,

just a short question on this. I want to use PA8 as MCO pin on my STM32F0-Discovery, so I set up everything but had to alter definitions in my board.h. All works.
I now just want to leave bord.h as is from repository and set up in an init funtion in main(). So I use but the compiler telles me function is not defined.
Can't I chnage pin behaviour this deep after board init?

Cheers
Stefan

Is it an F0 or an F1? that line works for the F1 only which has the old GPIO unit. For all the other STM32s it is:

palSetPadMode(GPIOA, 8, PAL_MODE_ALTERNATE(N));

Where N is the number of the alternate function, see the data sheet.

Awesome, thanks again for the help, Giovanni!
