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 PIN||DISCOVERY CONTACT|
|PF10 : GPIO candidate (useful!)||A1|
|PF9 : UART7CTS||A2|
|PF8 : UART7RTS||A3|
|PF7 : UART7TX||A4|
|PF6 : UART7RX||A5|
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?
