    How to connect RS485 device with PSoC4.

    william.jang_1506556

      Hi,

         

      I am using BLE Pioneer Kit (CY8CKIT-042-BLE) and trying to connect RS485 device to PSoc4.

         

      The datasheet of UART component of PSoC4 tells "The UART provides asynchronous communications commonly referred to as RS232 or RS485".

         

      As I know, 2 pins (TRXD+, TRXD- or A, B) are used for RS485 communication and these 2 pins are not dedicated "input pin" or "output pin".
      So I think "input pin" and "output pin" of this UART component should be changed to (TRXD+, TRXD- or A, B) if it will be used for RS485 mode, but it seems not to be changed.
      Can you please let me know how to connect RS485 device (it have 2 pins - TRXD+ and TRXD-) with UART component (it seems to have only dedicated input and output pin) of PSoC4?

         

      Thanks
      William
