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
Connect 12V~20V power supply and J-Link Debug Probe to the board, switch SW4 to power on the board.
Connect a micro USB cable between the host PC and the J31 USB port on the cpu board.
Open a serial terminal with the following settings:
115200 baud rate
8 data bits

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
