USB Type-C cable
MCIMX93-QSB board
J-Link Debug Probe
12V~20V power supply
Personal Computer
Board settings#
CM33: Connect input signal to J1406-3
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 SW301 to power on the board.
Connect a USB Type-C cable between the host PC and the J1708 USB port on the cpu board.
Open a serial terminal with the following settings:
115200 baud rate

No parity
One stop bit
No flow control
Download the program to the target board.
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
