5x5 LED Matrix

Output 5x5 LED image on board

Simulink Coder Support Package for BBC micro:bit/ LED

Description

The 5x5 LED Matrix block outputs a 5x5 LED image on a built-in 5x5 LED matrix on the board. The block has one input port, Matrix. The Matrix port accepts a 5x5 matrix with all the elements as either 0 or 1.

Use the 5x5 LED Matrix

The BBC micro:bit uses x, y coordinates to identify a particular LED in the 5x5 matrix. The coordinates start from 0 from the top-left corner of the matrix.

Place the board horizontally on a table with the LEDs facing upwards. The horizontal line represents the x-coordinates and the vertical line represent the y-coordinates.

Suppose that you are sending a matrix with values [1 0 0 0 1;0 1 0 1 0;0 0 1 0 0;0 1 0 1 0;1 0 0 0 1] as an input to the block. All the LEDs corresponding to elements with value 1 turn on.

The port accepts a 5x5 matrix with all the elements as either 0 or 1. When the element value is greater than 0, the corresponding LED turns on. Otherwise, it turns off.
