I've just started to toy around with Digi's XBee S2 ZigBee modules and my Tiva C-Series Launchpad. The XBees receive all their commands from any attached microcontroller via UART. I'm reading through the TivaWare UART API documentation, and it looks like the only function available to send data takes an ASCII character as an input rather than a hex value. Am I overlooking some other function that would take a hex value as an input, or do I have to convert my string of hex "characters" into ASCII first, then use the UARTCharPut() function?
