Hardware requirements

  • USB Type-C cable

  • MCIMX93-EVK board

  • J-Link Debug Probe

  • 12V~20V power supply

  • Personal Computer

Board settings

  1. Connect ADC channel1 (ADC_CH_01) to voltage supply which is less than 1.8v.

  2. Get ADC conversion data three times.

  3. Connect ADC channel1 (ADC_CH_01) to voltage supply which is more than 1.8v.

  4. Get ADC conversion data one time.

Please note this application can’t support running with Linux BSP!

Prepare the Demo

  1. Connect 12V~20V power supply and J-Link Debug Probe to the board, switch SW301 to power on the board.

  2. Connect a USB Type-C cable between the host PC and the J1401 USB port on the target board.

  3. Open a serial terminal with the following settings:

    • 115200 baud rate

    • 8 data bits

    • No parity

    • One stop bit

    • No flow control

  4. Download the program to the target board.

  5. Either re-power up your board or launch the debugger in your IDE to begin running the example.

Running the demo

When the example runs successfully, you will see similar information from the terminal shown below.
