Hardware requirements

Hardware requirements#

  • Mini USB cable

  • TWR-MC56F8400 board

  • Personal Computer

  • Multimeter

Board hardware common setting#

  1. Power setting:

    Connect J11 pin1 and pin2 Connect J6 pin1 and J7 pin2

  2. UART setting:

    Connect J8 pin3 and pin4 Connect J9 pin3 and pin4

  3. Onboard OSJTAG debugger setting:

    Connect J20 pin1 and pin2. Leave J17 open. Note: J17 is only used(connected) when firmware update for onboard debugger OSJTAG. Connect J21 pin 1-2, 3-4, 5-6, 7-8, to setup onboard debugger OSJTAG. Note: when use external debugger(connected to J14), leave all J21 pins open

Board settings#

No special settings are required.

Prepare the Demo#

  1. Connect USB cable between the host PC and the JM60 USB(J18) 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. Launch the debugger in your IDE to begin running the demo.

Running the demo#

When the demo runs successfully, the log would be seen on the terminal like:

DAC basic Example.

Please input a value (0 - 4095) to output with DAC:

Then change DAC value, and measure the voltage of DACA output pin. Use a multimeter to measure the voltage of J502-14, then you will get the voltage of DAC output. (Each DAC LSB represents 0.806 mV).
