Hardware

How are the LEDs connected on the WEMOS?

GND ----> Must be on GND
+5V ----> Must be on 5V
DIN ----> Is freely assignable (currently in the code at D7)

[WEMOS D1-mini](https://www.wemos.cc/en/latest/d1/d1_mini.html)

How are the LEDs connected on the M5?

GND ----> Must be on GND
+5V ----> Must be on 5V
DIN ----> Is freely assignable (currently in the code at G33)

[M5-Stack](https://www.bastelgarage.ch/m5stack-atom-matrix-esp32-development-kit)

The DIN connection can be set in the platformio.ini with the property -DPIXEL_PIN=xx to be changed.

You can install the Busylight e.g. on the monitor

Update to MC with Visual Studio Code

Start Visual Studio Code and open the Busylight Microcontroller folder.
First of all, you need to install PlatformIO IDE.
After that you can click on the ant on the side and then you just have to press "Upload".
