Download the program to the target board.
Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.
Running the demo
The log below shows example output of the SCTimer multi-state demo in the terminal window:
SCTimer example to output edge-aligned PWM signal
When user presses a switch the PWM signal will be seen from Out 2
When user presses the switch again PWM signal on Out 2 will turn off
The PWM signal from Out 4 will remain active all the time
Use a Digital osc probe on J13_5(Out 4) and J13_16(Out 2) to watch the PWM.
When press sw2 the PWM signal will be seen from J13_16.
When press sw2 again the PWM signal will turn off from J13_16.
