There are multiple ways to use UART0 as a debug interface. They are Debug Log and Serial Command Monitor. Debug Log is a built-in tool located at Driver Porting Layer of SDK. Like Serial Cmd Monitor, its function must be located out of interrupt callback. It is a handy tool enabling string input and output. But, input and output go through UART console only. There is no built-in GUI like Expression Window and Graph in CCS. It is recommended to disable UART0 in Debug Log at Figure 2-11 and configure UART0 instance for Serial Command Monitor at Figure 2-12. As the name of UART in Sysconfig, "CONFIG_UART_CONSOLE", matches the handle name in "Serial_Cmd_HAL.c", it not necessary to modify the two functions required by initialization and background loop. They can be simply inserted as Figure 2-13.
