I have a board CY8CKIT-042 (not ble),and I want to use modbus through rs485 unit.So I'd like to know how to set in creator.Maybe pin 3[0] and 3[1] could be used?Or maybe some resolutions else? Wish some discusses and answers about connecting lines, settings in creator or ways of using the library functions.Thanks

Hi

You can use UDB based UART in PSoc Creator and use an external driver IC to convert the PSoC UART based RX, TX  and TX enable signals to RS485 signals through external driver.

Please find the attached image for connecting the PSoC 4 to RS485 through external driver.

You can also look at the following thread for more information.

How to connect RS485 device with PSoC4.

Thanks
