I've enabled interrupts on the UART but the void UART_EnableRxInt(void) function doesn't exist in the UART_XXX.h file or .c file. Why is the API not being generated?
Welcome in the forum, John!
Can you please post your complete project, so that we all can have a look at all of your settings. To do so, use
Creator->File->Create Workspace Bundle (minimal)
and attach the resulting file.
Location of the project is too deep in the folder directory.
