RS-232/UART Hardware fix for CY8CKIT-001/030/050
In the following Kits :
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.
