Pin Function Document

[skon.1]

Hello,

I'm using the NUCLEO-F722ZE EVB.

In page 43 of the following document there seems to be a pinout list which specifies the signal name of each pin :

But how can I know what functionality a specific pin supports ?

For example :

How do I know if pin PF8 can be a DAC output ? Is there another document that describes that ?

CubeMX (or CubeIDE) to the rescue! Select the board, then on the chip picture click on the PF8 pin. It will show all functions of that pin.

That would be the Data Sheet for the micro-controller on the board, ie STM32F722ZE

The pinout table will tell all digital and analog alternate functions. Typically the dacs when present are in PA4 and PA5, and these pins are also wired to the ADC so without wires you can self test it.

Thanks,

How can they be tested without wires ? Is there an internal loopback between DAC and ADC that can be activated ?
