Example Description
|
|
|
|
This example describes how to use GPIO read/write mbed api to generate a pulse and to measure the pulse width.
|
|
|
|
Requirement Components:
|
|
a wire
|
|
|
|
Pin name PC_4 and PC_5 map to GPIOC_4 and GPIOC_5:
|
|
- PC_4 as the interrupt GPIO pin with no pull (High-Z).
|
|
- PC_5 as output to generate a pulse.
|
|
- Use a wire to connect PC_4 and PC_5
|
|
|
|
In this example, the UART consol will print out the measured width (in us) of the pulse which generated by PC_5.
