Personal Computer
Board settings
Output signal Board location
SCT0_OUT4 J3-3 (P1_22)
Prepare the Demo
Connect a type-c USB cable between the PC host and the MCU-Link USB port (J17) on the board
Open a serial terminal with the following settings (See Appendix A in Getting started guide for description how to determine serial port number):
115200 baud rate
8 data bits
No parity
One stop bit
No flow control
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 driver PWM demo in the terminal window:
SCTimer example to output center-aligned PWM signal
You will see a change in LED brightness if an LED is connected to the SCTimer output pin
If no LED is connected to the pin, then probe the signal using an oscilloscope
You’ll see PWM signals with changing duty cycle on J3_3 using an oscilloscope.
