Hardware requirements

• Type-C USB cable

• FRDM-MCXN236 board

• Personal Computer

Board settings

P4_19(J8-11) connect to CTimer simple PWM.

Prepare the Demo

1. Connect a type-c USB cable between the PC host and the MCU-Link USB port (J10) on the board

2. 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

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 CTimer simple PWM demo using interrupts in the terminal window:
