NUCLEO - F303RE Alternate function mapping

Where can I find the alternate function mapping for GPIO pins? 

Normally these can be found in User Manual for a given card, but I can't find it for the NUCLEO-F303RE.

You need to do it in two steps: first, in Nucleo's UM, you find the connector-to-pin mapping:

and then in the 'F303RE datasheet look up the pin-to-alternate function table.

Data Sheet for the CHIP not the manual for the BOARD

This is what I meant (in the '2018 Wish List' post) about having this data in a 'manipulatable' format.

I would try to find & link to it - but I don't think it's worth it with the current state of the forum.

:(

 

My usual approach is to first get the device UM 

pin-to-alternate function table into Excel, then the board 

connector-to-pin mapping into Excel, the use Excel's VLOOKUP (table look-up) feature to join the two together.

(other spreadsheet programs are available)

Start the CubeMX, select for example PA10 as usart and press Ctr and left mouse botton - you will see alternate pin  - PB7 in this case
