The RevPi MIO has a GPIO interface with four connections, which you can use as an option in various operating modes:
- PWM input
- PWM output
- Pulse measurements
- Pulse output
- GPO 24 V level output
- GPI 24 V
You can set the mode you require in PiCtory.
The digital inputs and outputs use the same ground as the analog inputs and outputs. For this reason you should use one of the system ground connections on the 28-pin connector strip. If you don”t use this ground, it”s possible that your values will be distorted. If the voltage between the system ground and the ground of the digital inputs and outputs is too high, the protective diode can also be destroyed.
