I was working getting getting what i call a Load pin to toggle properly in an application I am trying to do with sending data out a UART. I was able to get my load pin to toggle off properly with a UART completion of data interrupt. Now I need the Load pin to go Hi at the falling edge of the UART sending data. I tried to attach an input pin to the TX pin of the UART and sense a falling edge but I get errors when i try to do this in Creator. Does anyone know how I can do such a task. I would like the pin to be in sync with the TX pin going low ... and the load pin going hi at same time.
You can do what you are trying if you use an UDB implementation of the UART. If using the SCB block, no connections to the RX/TX lines are allowed.
If you need to use the SCB block, what you can do is to short the TX pin to a second pin externally, and then add your logic around this second pin.
