  • MC56F80000-EVK board

  • Personal Computer

Board hardware common setting

  1. Power setting:

    Connect J8 pin2 and pin3 Connect J6 pin1 and pin2 Connect J5 pin1 and pin2

  2. Reset pin setting:

    Connect J11 pin2 and pin3

  3. Debugger setting:

Prepare the Demo

  1. Connect USB cable between the host PC and the J12 USB port on the target board. It setups Multilink and COM port in PC device manager.

  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 with Multilink debug configuration.

  4. Launch the debugger in your IDE to begin running the demo.

Running the demo

When connect a 50% duty cycle 1KHz PWM signal to input and the demo runs successfully, the following message is displayed in the terminal:

****Input capture example.****

****Provide a signal input to the QTMR pin****

The pulse width of the captured PWM is 500 us !
Press any key to trigger the next capture !
