Hi All,
I am aware that the PSOC 4 SCB UART is fixed to a few groups of pins on a device. Can I use the HSIO matrix to change the pins to another set of pins of my choosing and it still work? I don't need to dynamically change back and forth all I want is for them to be set and they work. I already made 50 boards and I am stuck with the device and trying to fix a mistake I made. The current device I am using is CY8C4244LQI-443 and the current pins the SCB UART are on is P3[0] (RX) and P3[1] (TX). I want P1[7] (TX) and P2[0] (RX) if possible. Can anyone help me out please 😃? If there is a better way to do this I am open to ANY suggestions. Is there a software based UART that receives and transmits? I am aware of the SW TX Uart. I tried using the UDB based UART but that doesn't fit in two UDB's 😓.
For what it is worth I found this:
https://community.cypress.com/t5/PSoC-4-MCU/Dynamic-reconfiguration-of-UART-pins/td-p/126450
I want to do something similar as to what was done in this link but can't figure out what in the world the HSIO stuff means to make it useful for my predicament.
Thanks,
Eric

Hi,
I tried the followings.
Use SCB only for RX, use SW for TX.
At least I could generate application.

Hi Moto,
Yeah I tried that and may be my only option unless there is something else I can try. The only thing I don't like is that it is two separate components. Ill keep going and see if I can figure something out. Thanks for your response :-).
