No special is needed.
Prepare the Demo
Connect a USB cable between the host PC and the FRDM board J10.
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.
Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.
Use oscilloscope to measure the output 100KHz PWM signal pin at J1-6 pin.
Running the demo
When the example runs successfully, if the input duty cycle range is 0~100, You can see similar information from the terminal as follows:
FLEXIO_PWM demo start.
Please input a value (0 - 100) to set duty cycle: 10
Input value is 10
PWM duty cycle is: 10
PWM leave is: 0
Please input a value (0 - 100) to set duty cycle: 150
Input value is 150
Your value is output of range.
Set pwm output to IDLE.
Please input pwm idle status (0 or 1): 1
Input IDLE state value is 1
PWM leave is: 1
Please input a value (0 - 100) to set duty cycle:
......
Note:
The duty cycle of the PWM is variable, except for the idle state, 0 and 100.
If the input duty cycle range exceeds 100, the pwm will be set to idle state
If the set pwm idle value is out of range, it will output “Your value is output of range.” and then return to set the duty cycle.
