EK-TM4C123GXL: CCS Code for Sending Characters or Hex Values Serially?

Hello Rob,

We have a number of examples to use UART for outputting characters.

I would recommend you start by referencing our 'Hello' example in TivaWare, which you can download here: https://www.ti.com/tool/SW-TM4C

You can find the example in the folder [Install Path]/TivaWare_C_Series-2.2.0.295\examples\boards\ek-tm4c123gxl

We also have a Timer example that you can use to handle the 3 second interval aspect, look for the 'Timers' project.
