Hardware requirements

  • Micro USB cable

  • MC56F83000-EVK board

  • Personal Computer

  • Oscilloscope

Board hardware common setting

  1. Power setting:

    Connect J19 pin2 and pin3 Connect J12 pin1 and pin2 Connect J13 pin1 and pin2 Connect J15 pin1 and pin2 Connect J16 pin2 and pin3 Connect J17 pin1 and pin2

  2. Onboard OSJTAG debugger setting:

    Leave J5 open Leave J6 open Note: J6 is only used(connected) when firmware update for onboard debugger OSJTAG. Connect J11 pin 1-2, 3-4, 5-6, 7-8, to setup onboard debugger OSJTAG. Note: when use external debugger(connected to J10), leave all J11 pins open.

Board settings

  • Use oscilloscope to monitor J4-7.

Prepare the Demo

  1. Connect USB cable between the host PC and the JM60 USB(J8) port on the target board. It setups OSJTAG 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 OSJTAG debug configuration.

  4. Either press the reset button on your board or launch the debugger in your IDE to begin running the demo. Please be noted that default FCF(flash configuration field) setting makes MCU boot from bootloader. So after reset button press, it will wait 5s(wait in bootloader) to run the application code.

Running the demo

When the demo runs successfully, the following message is displayed in the terminal:


****Output PWM example.****

*********Make sure to connect an oscilloscope.*********

****A 50 duty cycle PWM wave is observed on an oscilloscope.****

Please enter a value to update the Duty cycle:
Note: The range of value is 1 to 9.
For example: If enter '5', the duty cycle will be set to 50 percent.
Value:5
The duty cycle was successfully updated!
