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

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 |
| 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. |
