Hardware requirements#
Mini/micro USB cable
MIMXRT1180-EVK board
Personal Computer
Oscilloscope
Board settings#
Input PWM signal to J45-15. PWM signal: 0-3.3V, default 1KHz.
Use oscilloscope to monitor the signal at J45-13.
Prepare the Demo#
Connect a USB cable between the host PC and the OpenSDA USB port on the target board.
Open a serial terminal with the following settings:
115200 baud rate
8 data bits
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 demo.
Running the demo#
When the demo runs successfully, the following message is displayed in the terminal:
****Input capture example.****
****Provide a signal input to the QTMR pin****
Captured Period time=1000 us
****Output PWM example.****
*********Make sure to connect an oscilloscope.*********
****A 50 duty cycle PWM wave is observed on an oscilloscope.****
