Supported Targets: Olimexino, E407, P405

A 'Digital Input' block reads the input level of the selected pin. If the input level is high, '1' is the output, otherwise '0'.

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.
