Hardware Direction change #9
Description
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.

Hi, sorry replying late, and github didn't notify me of issues.
Regarding communication direction, OSDP is designed for RS485, which is half-duplex. You can use burst communications to control the direction, where each computer kicks out its messages then sniffs for packets.
