You'd need to put the USART in 9-bit mode, and probably read the reference manual.

Seem to recall there being examples in the SPL, but if you need code to look at you're probably going to need to search for it.

No experience with RS485, although I recall it's a half duplex protocol.

Used single master multiple MCU slaves with SPI for <1m range, works fine.
