Including HAL drivers from ST in chibios

[milom]

Hi Giovanni, I did well to complete the work of importing the chibios to Keil, now I would like to include the HAL st in the project, only for some devices, so I can take advantage of some of the work I did, for example on my graphics drivers. I leave including the GPIOs of the HAL ST. I have included the file stm32f4xx_hal_gpio.c without problems activating all dependencies. I have a GPIOD compatibility problem though. Do I have to exclude the PAL libraries? I have no way to include the two drivers? thank you.

Try disabling the PAL driver, there could be conflicts in registers definitions, the PAL driver uses its own structure.

Thanks for the quick answer Giovanni, turning off the pal driver works, but I also sept the analog pins with the chibios driver ... and the project include a setting of analog pins with palSetGroupMode (... or even the uart driver with ..palSetPadMode ( GPIOA, 9, PAL_MODE_ALTERNATE (7));
palSetPadMode (GPIOA, 10, PAL_MODE_ALTERNATE (7)); ... how to behave in these cases? thanks

Hi,

You need to decide which framework to use for GPIO settings. Making those compatible would require changes to some extent.

I understood, the initialization of the pins with the HAL ST method does not affect the use of the drivers or not? that is, I can initialize the pins as HAL ST and then use the chibios driver, I think there is no problem with the PAL drivers or not?

Thanks for your patience...

Hi,

You can use ST HAL to change pins, this will not affect other drivers except SPI in SW-CS mode, that has a dependency on PAL but you can use another mode or drive CS directly.

Thanks Giovanni for your efforts... grazie per il meraviglioso lavoro che metti a disposizione del mondo. Scusa l'italiano ma in periodi come questi, fiero di esserlo e fiero di questo lavoro tutto italiano.. sorry for paraphrase in Italian...
