Hardware requirements

• Type-C USB cable

• FRDM-MCXC444 board

• Personal Computer

Board settings

No special is needed.

Prepare the Demo

1. Connect a type-c USB cable between the host PC and the MCU-Link USB port (J13) on the target 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. Connect external signal source J6-2 to user-defined channel, defined by “DEMO_ADC16_USER_CHANNEL” in source code. Shorten jumper JP6 to use external reference voltage pair pins.

4. Download the program to the target board.

5. Either press the reset button on your board or 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:

ADC16 polling Example. ADC16_DoAutoCalibration() Done. ADC Full Range: XXXX Press any key to get user channel’s ADC value … ADC Value: 1985 ADC Value: 1689 ADC Value: 1355 ADC Value: 1625 ADC Value: 1575 ADC Value: 1471
