ChibiOS Free Embedded RTOS

Hi,
just an easy question, to choose from possible pin to use for usartX, i just have to activate their alternative mode them with:



so does this also mean activanting altenate mode on two or more pair of TX/RX (of the same uart) use them all as uart?

Hi,

Note that the alternate modes must be selected only for a single pair of pins, you must not map the UART (or any other peripherals) to more than one pin so verify the defaults in board.h.
