trgmux_clone_pwm#

Overview#

The TRGMUX project is a simple demonstration program of the SDK TRGMUX driver. It generates a 10KHz PWM by LPIT0 CH0, and clone by TRGMUX to output this PWM to eight TRGMUX_OUTx pins.

Supported Boards#

FRDM-KE15Z
Hardware requirements
  • Micro USB cable

  • FRDM-KE15Z board

  • Personal Computer

Board settings

The example requires connection between the trgmux pin and oscilloscope. Connect each of the trgmux output pin with the anode of oscilloscope: J21-8(FRDM-KE15Z board) -> Anode of oscilloscope. Or J21-7(FRDM-KE15Z board) -> Anode of oscilloscope. Or J4-2 (FRDM-KE15Z board) -> Anode of oscilloscope. Or J4-4 (FRDM-KE15Z board) -> Anode of oscilloscope. Or J4-11(FRDM-KE15Z board) -> Anode of oscilloscope. Or J2-17(FRDM-KE15Z board) -> Anode of oscilloscope. Or J2-15(FRDM-KE15Z board) -> Anode of oscilloscope. Or PTD0 (FRDM-KE15Z board) -> Anode of oscilloscope. GND (FRDM-KE15Z board) -> Cathode of oscilloscope.

Prepare the Demo
  1. Connect a USB cable between the host PC and the OpenSDA USB port 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

  1. Download the program to the target board.

  2. Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.

Running the demo

When the example runs successfully, you can see the 10KHz PWM on each of the 8 pins.
