RS-232/UART Hardware fix for CY8CKIT-001/030/050 - Cypress.com Forums http://www.cypress.com/? Re: RS-232/UART Hardware fix for CY8CKIT-001/030/050 http://www.cypress.com/?rID=60748 We have a saying here (in Germany)

 

To connect 2 wires arbitrarily gives you a 50% chance to make it right. Statistics shows that these 50% are used up to nearly 100%.

Re: RS-232/UART Hardware fix for CY8CKIT-001/030/050 http://www.cypress.com/?rID=60747 Can you please review the suggested wire-connections?

The pin 2 is named twice in the left-hand column, probably the first line should read

3 -> 2 ???

Re: RS-232/UART Hardware fix for CY8CKIT-001/030/050 http://www.cypress.com/?rID=60741 There is an ambiguity in the way the TX and RX pins are labelled, too. I would expect the TX pin (nect ro the RS232 port) to be the source and the RX pin to be the sink. However, it is the OTHER WAY AROUND. As a result I have to wire the PSOC's TX pin (say P1_6) to the TX pin and the RX to RX with is kinda non-intuitive...

Re: RS-232/UART Hardware fix for CY8CKIT-001/030/050 http://www.cypress.com/?rID=54158 Correction: Only the CY8CKIT-001 has this error. The CY8CKIT-030/050 boards have been corrected.

(I was looking at an older schematic....)

Re: RS-232/UART Hardware fix for CY8CKIT-001/030/050 http://www.cypress.com/?rID=54129 You're welcome.

Yes, that PCB/Layout error took me a little head thumping to recognize.

Cypress seems to have cut-n-pasted it into their most recent CY8CKIT-030/050 boards as well.

The simple solution is to get yourself a solder end male DB-9 and solder end female DB-9

and solder up a little adaptor cable to fix this.  I have an example picture attached...

This is necessary to use any hardware handshaking.

best regards,
