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.
x — Input signal
Input signal from the hardware logic. Each LED has a port, named
LED1 to LED
x is Number of LEDs.
Hardware board — View selected hardware
None (default) | Supported Xilinx® or Intel ® boards | Custom boards
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.
This button is enabled only when you select specific Xilinx or Intel boards. For more information about these boards, refer to Supported Third-Party Tools and Hardware.
IO logic — IO logic indicator
None (default) | Active High | Active Low
This parameter is read-only. Indicates the IO logic level on the selected hardware board.
When the IO logic parameter is shown as Active Low, the LED block accepts active low signals and represents the port names prefixed with letter n. For example, nLED1.
Number of LEDs — Number of LED ports
1 (default) | list of integers in the range [1, n]
Specify the required number of LED ports by specifying a value from this list.
n is the number of available LEDs on the specified hardware
board. For example, if you set this parameter to
4, the block
shows four LED ports.
To use only the
nth LED, set the Number of
LEDs parameter to
n and leave the unused LED
For the Zynq®
UltraScale+™ RFSoC ZCU216 Evaluation Kit, the first three LED ports represent the first
set of red, green, and blue (RGB) LEDs out of the eight available sets, the next three
LED ports represent the second set of RGB LEDs, and so on. For example, if you set the
Number of LEDs parameter to
LED1, LED4, and LED7
ports connect to the red LEDs, the LED2, LED5,
and LED8 ports connect to the green LEDs, and the
LED3, LED6, and LED9
ports connect to the blue LEDs on the ZCU216 evaluation board.
