STM32F37x ADC vs SDADC clocks Topic is solved

[dflogeras]

Hi,

I'm using ChibiOS-16.x.y on a stm32f372. I'm currently using the SDADC to perform conversions, but this requires me to set HAL_USE_ADC.

The side effect I'm noticing is that I cannot scale the APB2 clock tree down as far as I'd like because it is requiring me to stay within the acceptable range for the ADC peripheral. Could this be addressed in a future version? Is there a technical reason I shouldn't be able to do this?

Thanks,
Dave

Hi,

Moving this in "bug reports", this limitation is not intentional, probably the check should be modified.

Hi,

I committed a change in trunk about this. Will backport if requested.

Hey Giovanni, thanks for this patch

It looks like you may have a copy/paste error in 12060, you repeated SDADC1 three times, I bet you meant SDADC1 | SDADC2 | SDADC3.

Where exactly? I cannot find that.

Sorry about that, lines 856 and 862 of os/hal/ports/STM32/STM32F37x/hal_lld.h
