Nucleo F429ZI DAC/ADC

Why isn't possible to run ADC on some pins in the yellow ring on the picture, but different pins yes?
In the datasheet, it should work.
Is it possible to repair it in firmware?

Code: Select all

#F3=pyb.ADC('PF3') #A3
#F5=pyb.ADC('PF5') #A4
Traceback (most recent call last):
  File "<stdin>", line 18, in <module>
ValueError: pin F3 does not have ADC capabilities
And why the pyb library does not contain DAC?

Thank you for your responses.

why isn't implemented PWM in the machine library for nucleo f429zi?

Thank you for your response.

I was able to get the DAC to work by adding the following line


to the end of


and recompiling the micropython firmware.
