need to do this, but be able to do it on multiple pins at same time, not just one.  Is there a way I can do this, so I can send my data on all the pins at the same time?

Thanks

If you use an UDB UART implementation, you can do whatever you want with the output, including the things you tried.

If you use the SCB UART implementation, than you can only do a direction connection to the pin. Or, if the PSoC 4 you chose has Smart I/O, you have a few options to multiplex the signal to different pins in the same port.

Hello Doorknob,

 

maybe you can use something like this:

You can use UART on several pins at the same time and control them with the control registers. When I record the outputs with the logic analyzer, I get my UART signal on different pins at the same time.
