Hello,

You could try the LED Matrix (Serial) component available under Outputs -> LEDs.

You would only need to connect the DataIn and Clock signals to the dot matrix. You may also need to tie the CS pin to either GND or VCC depending on the wiring of the module.

In the component properties set the row count to 8 and column count to 32 and then set Redraw LEDs property to yes to redraw the component.

Let us know how you get on.
