M5Unified Add-On Library for Arduino

Connects MATLAB to M5Stack hardware using the Arduino M5Unified Library.

M5Stack support for MATLAB

Connect to an M5Stack ESP32 based device using the MATLAB Support Package for Arduino hardware. This Custom Arduino Add-On Library allows you to communicate with the integrated peripherals on M5Stack(IMU,LCD,MIC,PMU,SPKR,etc.) using the M5Unified & M5GFX Arduino Libraries.

To get started, you need:

1. MATLAB.
2. ESP32 based M5Stack (Core, Core2, Stick, Stick2,Atom).
3. MATLAB Support Package for Arduino hardware.
4. M5Unified & M5GFX Arduino Libraries installed in the arduino libraries folder.
5. M5Unified Add-On Library for Arduino (this).

Connecting to the M5Stack

Once the environment is set up, we will create two objects in our workspace.

1. An 'arduino' object that represents the ESP32 microcontroller .
2. An 'addon' object that represents the M5Unified Libraries & the devices M5Unified controls.

First: Initialize communication with the ESP32 inside the M5Stack.

Example:

esp32 = arduino('COM6','ESP32-WROOM-DevKitC','Libraries',{'I2C','M5Stack/M5Unified'});

Second: Initialize the M5Unified Arduino Add-On Library.

Example:

M5Unified = addon(esp32,'M5Stack/M5Unified');

Controlling the M5Stack

Use the 'arduino' object namespace to communicate with the ESP32.

Example:

 esp32.writeDigitalPin('D32',0);
 esp32.readVoltage('D33');

Use the 'addon' object namespace to communicate with the M5Stack components.

Example:

 M5Unified.lcdPrint('Hello');

Notes

• This Library is in active development and more features will be added over time.
• Created using MATLAB 2024a, it likely works with any version of the arduino support packages that supports ESP32.
• Developed using the M5 Core2 for AWS, and some testing with the M5 StickC has been done.
