Connect signals attached to LEDs on hardware board
SoC Blockset / Hardware Logic I/O
The LED block indicates the status of a signal. The hardware logic signals connected to an LED block are equivalent to the signals connected to the Light Emitting Diodes (LED) on the hardware board.
Intel® hardware boards operate with active low signals. When you select an Intel hardware board, the LED block accepts active low inputs and it represents the port names prefixed with letter "n". For example, nLED1.
LED— Input signal
Input signal from the hardware logic. There is a port for each LED, named
LED1 to LED
x is Number of LEDs.

This parameter is read-only. To choose a hardware board and configure board parameters, see Hardware Implementation Pane.
View LEDs location— View LEDs
To view a diagram of the location of the LEDs on the selected hardware board, click the View LEDs location button.
Number of LEDs— LED selection
1(default) | list of integers in the range [1, n]
To specify the required number of LED ports, select a value from the
Number of LEDs list.
n represents the number
of available LEDs on the specified hardware board.
For example, if you select
4 from the list, the block
shows four LED ports.
