I am using the SC16IS752 connected to my raspberry as well, which works okay.. As RS232 uarts.. The datasheet for the chip states that by setting bit 4 of the EFCR register, this chip is capable of driving the direction of a RS232<->RS485 transceiver like the MAX485 through the RTS pin. Once this bi...

The SC16IS752 also supports RS485 mode, which takes care of the direction control needed to ...
