Hardware requirements

  • Micro USB cable

  • IMX95LPD5-EVK board

  • J-Link Debug Probe

  • 12V~20V power supply

  • Personal Computer

Board settings

  • CM33: Connect input signal to R881

  • note: square wave at fixed rate is recommended as the input signal for easily checking the result.

Prepare the Demo

  1. Connect 12V~20V power supply and J-Link Debug Probe to the board, switch SW4 to power on the board.

  2. Connect a micro USB cable between the host PC and the J31 USB port on the cpu 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. Launch the debugger in your IDE to begin running the example.

Running the demo

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

TPM dual-edge capture example

Once the input signal is received the input capture values are printed

The input signal's pulse width is calculated from the capture values & printed

Capture value C(n)V=8c40

Capture value C(n+1)V=e104

Input signals pulse width=904 us
