    RS-232/UART Hardware fix for CY8CKIT-001/030/050

    user_7880656

      In the following Kits :

         

      CY8CKIT-001
      CY8CKIT-030
      CYC8KIT-050
       

         

      There is a problem with Hardware Handshaking in that the CTS/RTS pins are swapped on the development kits.
      This is a hardware/PCB error on the circuit boards and can only be fixed by a wiring change.

      There are two workarounds to this problem :

         

      1) Don't use hardware handshaking, select software handshaking (3 wire protocol) only.

      2) Wire a DB-9 Female to DB-9 Male adaptor plug with the following pinout :

         

      2 -> 2
      2 -> 3
      7 -> 8
      8 -> 7

         

      There is also an issue in PSoC5 with clock frequency drfit at high baud rates.
      Enable the External Crystal to act as your Baud rate source for stable communications.
