M5Stack Core2 ESP32 IoT Development Kit DocumentationOverviewThe M5Stack Core2 ESP32 IoT Development Kit is a powerful and feature-rich development board designed for IoT projects. It is based on the ESP32 microcontroller, which provides built-in Wi-Fi and Bluetooth capabilities, making it an ideal choice for a wide range of IoT applications.Key FeaturesESP32 microcontroller with Wi-Fi and Bluetooth capabilities
2.4-inch color LCD display with 320x240 resolution
Built-in microSD card slot for storage expansion
USB-C interface for programming and power supply
Multiple GPIO pins for peripheral connections
Support for various programming languages, including MicroPython, Arduino, and LuaCode Examples### Example 1: Wi-Fi Connection and LCD DisplayThis example demonstrates how to connect to a Wi-Fi network and display a message on the LCD screen using MicroPython.
```python
import network
import lcd# Initialize Wi-Fi module
wifi = network.WLAN(network.STA_IF)
wifi.active(True)
wifi.connect("your_wifi_ssid", "your_wifi_password")# Wait for Wi-Fi connection
while not wifi.isconnected():
passprint("Connected to Wi-Fi")# Initialize LCD module
lcd.init()
lcd.clear()
lcd.print("Hello, World!", 0, 0, lcd.WHITE, lcd.BLACK)
```
Replace "your_wifi_ssid" and "your_wifi_password" with your actual Wi-Fi network credentials.### Example 2: Bluetooth Low Energy (BLE) AdvertisingThis example demonstrates how to use the M5Stack Core2 to advertise a BLE service using Arduino.
```cpp
#include <BLE.h>BLEServer server;
BLEService service;
BLECharacteristic characteristic;void setup() {
Serial.begin(115200);// Create a BLE server
server = new BLEServer();// Create a BLE service
service = server->createService("uuid_of_your_service");// Create a BLE characteristic
characteristic = service->createCharacteristic("uuid_of_your_characteristic", BLECharacteristic::PROPERTY_NOTIFY);
}void loop() {
// Start advertising
server->startAdvertising();delay(50);
}
```
Replace "uuid_of_your_service" and "uuid_of_your_characteristic" with your actual BLE service and characteristic UUIDs.### Example 3: MicroSD Card File AccessThis example demonstrates how to read and write files on a microSD card using Lua.
```lua
-- Initialize microSD card module
-card = dofile("sdcard.lua")-- Mount the microSD card
card.mount()-- Create a file on the microSD card
local file = card.open("example.txt", "w")
file.write("Hello, World!")
file.close()-- Read the file from the microSD card
file = card.open("example.txt", "r")
local content = file.read()
print(content)
file.close()-- Unmount the microSD card
card.unmount()
```
Make sure to replace "sdcard.lua" with the actual path to the microSD card library file.ConclusionThe M5Stack Core2 ESP32 IoT Development Kit is a versatile and powerful tool for building IoT projects.
