Hardware requirements

  • Micro USB cable

  • MC56F83000-EVK board

  • Personal Computer

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

No special settings are required.

Note: The sample0 works in fully differential mode and the differential pair is selected as ANA6 and ANA7. And the thermistor in MC56F83000-EVK board is connected to ANA6 and ANA7.

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 example runs successfully, the following message is displayed in the terminal:

CADC continuous edma conversion.
Press any key to get user channel's ADC value ...
ADC value: 3122

User can press any key to get more converter data. The ADC input channel is connected with thermistor, so touching thermistor on board will get the ADC value updated.
