29.6. Quick to Start#
29.6.1. Materials Required and Diagram#
Connect the 8x16 Matrix module to the IIC port in the Nezha expansion board as the picture shows.
29.7. MakeCode Programming#
29.7.1. Step 1#
Click “Advanced” in the MakeCode drawer to see more choices.
We need to add a package for programming, . Click “Extensions” in the bottom of the drawer and search with “PlanetX” in the dialogue box to download it.
Note: If you met a tip indicating that the codebase will be deleted due to incompatibility, you may continue as the tips say or build a new project in the menu.
29.7.2. Step 2#
29.7.3. Code as below:#
The expresssions display on the 8x16 matrix module.
29.8. Python Programming#
29.8.1. Step 1#
Download the package and unzip it: PlanetX_MicroPython
Go to Python editor
We need to add matrix.py for programming. Click “Load/Save” and then click “Show Files (1)” to see more choices, click “Add file” to add matrix.py from the unzipped package of PlanetX_MicroPython.
29.8.2. Step 2#
from microbit import * from matrix import * matrix = MATRIX() x, y = 0, 0 while True: for y in range(8): for x in range(16): matrix.set_matrix_draw(x, y) matrix.set_matrix_clear()
Each LED lights on from the sequence of left to right and up to down, then they light off after all the LEDs light up.
