Digital Input

Read the logical value of a digital input pin


Simulink Coder Support Package for NXP FRDM-KL25Z Board/FRDM-KL25Z

  • Digital Input block


Read the logical value of the selected digital input pin. There are 14 pins on the FRDM-KL25Z board that you can use as inputs for digital signals, D0-D13. The digital pin layout for this board is compatible with the standard Arduino Digital Pins.

During simulations without the hardware, this block emits zeroes.



Select a digital pin.

Make sure not to assign the same pin number to multiple blocks within your model.

Sample time

Specify how often this block reads a digital pin value, in seconds. This parameter value defaults to 1/10 second.
