GPIO Pin Description
Location of Pins
GPIO pin usage:
The Isolated GPIO input is quite different to the Non-isolated GPIO input:
- To detect a situation where it is either ground or no ground, we should use a Non-isolated GPIO input;
- In a situation where we need to detect a signal either a voltage or a ground, we should use an Isolated GPIO input.
- Also we should always make use of the Isolated GPIO input common ground pin when we want to use an Isolated GPIO input;
- the voltage or ground must be recognized by the Spider GPIO interface for it to work.
Input Signal Classification
The GPIO input signals can be classified as below:
