Hardware requirements

  • Micro USB cable

  • MIMXRT685-AUD-EVK board

  • Personal Computer

Board settings

This example project uses ACMP instance 0 to compare the voltage signal input from channel A(J48-22) with the voltage signal(half of VDDA) output by ACMP’s internal DAC. In order to observe the low power wakeup phenomenon, channel A(J48-22) should be connected to GND signal(J25-1) on the board before the example running. Example will exit deep sleep mode when channel A(J48-22) is disconnected from GND signal and the disconnected time is last for about 1s.

Prepare the Demo

  1. Connect a micro USB cable between the PC host and the CMSIS DAP USB port (J5) on the board

  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.

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