I am trying to use the library with a hat. I am using GPIO 14&15 and using RTS (GPIPO 17) as the direction change. I can see data on the UART, no state change to change the direction on the RS485 transceiver.
Is there a method to change the transceiver direction. I realise if you are using a USB 485 transceiver this is not an issue, or it is handle directly by the hardware.
