[STM32F746-Discovery] Is it OK to use analog pins for UART7?

Question asked by Ivan Ivan on Jun 23, 2017

Hello. I'm having problem with USART6 (again). So I'm testing now UART7. By checking documentation I have found that it is theoretically possible to set up uart7 on analog pins. I have made such conclusion after looking at p.21 of Discovery User Manual and by looking of p.76 of MCU User Manual:

MCU PINDISCOVERY CONTACT
PF10 : GPIO candidate (useful!)A1
PF9 : UART7CTSA2
PF8 : UART7RTSA3
PF7 : UART7TXA4
PF6 : UART7RXA5

I'm confused because contacts A1-A5 are marked as analog and they are hooked to Alternative Functions related to Analog-to-Digital-Converter (in Discovery User Manual). (I'm new with electronics and I'm afraid to damage the Board)

UART7 requires digital signals, I suppose.

Is it OK to use these Discovery contacts for UART7?
