looking at running a Modbus master on the FX30S and would need to setup the interface properly.
I have found some similar topics but they are years old so doublechecking what is the correct procedure to get this going.
- Setup the UART to service RS485
14—RS-485 Linux application (Note: Not available for UART 2)
1—UART 1 (Default if UART number is not specified)
Does this does all the setup or I also need to control the GPIO, for some reason I can only find the hardware guide for the FX30S WP85.
