General information about Digital Input

A 'Digital Input' block reads the input level of the selected pin.If the voltage on the pin comes below the 'low level voltage' the output will switch to 0 and if it comes above the 'high level voltage' it will switch to 1. Please check the datasheet for the voltage levels.





Block outputs (outports)

A value that indicates the state of the pin. The data type is boolean, 0 for low level and 1 for high level.

Block parameters

Parameter Description
Input pin The input pin to be used for the digital input. Select one from the list. A warning will appear when the pin is already in use in another block.
Configuration The configuration to be used. There are three options:

- Floating, the pin will not connected in any way to ground or 3.3V
- Pull up, the pin will be connected to ground through a pull-down resistor
- Pull down, the pin will be connected to 3.3V through a pull-up resistor

Sample time Sample time of the block. The Sample time (in seconds) defines the rate at which the block is visited by the real-time scheduler of the target. The value of the Sample time has to be an integer multiple of the base sample time of the model.
