The MCUXpresso IDE SWO trace function is a special feature which enables user to observe variable update, interrupt entry/exit timing, interrupt event statistic, to print information in SWO ITM Console while the MCU is running. The MCUXpresso IDE SWO trace function is a supplement to the debugger of the MCUXpresso IDE. The main advantage is to display variable, print information, list interrupt entrying/exitting/returing while the MCU is running.
The documentation describes the hardware connection to implement the SWO function, MCUXpresso configuration and source code to implement the function.
