• Personal Computer

Board settings

No special settings are required.

Prepare the Demo

1. Connect a micro USB cable between the host PC and the LPC-Link USB port (J8) on the target board.

2. Open a serial terminal with the following settings:

   • 115200 baud rate

   • 8 data bits

   • No parity

   • One stop bit

   • No flow control

3. Download the program to the target board.

4. 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

• Use a Digital osc probe on J13_5 to watch the PWM.
