Code Examples

Here are three code examples demonstrating how to use the M5 Stack PROTO Module with Extension & Bus Socket in various contexts:

Example 1: Basic LED Blinking with ESP32

In this example, we'll use the M5 Stack PROTO Module with Extension & Bus Socket to blink an LED connected to the extension socket.

```c
#include <M5Stack.h>

#define LED_PIN 21 // Pin 21 on the extension socket

void setup() {
  M5.begin();
  pinMode(LED_PIN, OUTPUT);
}

void loop() {
  digitalWrite(LED_PIN, HIGH);
  delay(1000);
  digitalWrite(LED_PIN, LOW);
  delay(1000);
}
```

Example 2: I2C Communication with a Sensor Module

In this example, we'll use the M5 Stack PROTO Module with Extension & Bus Socket to communicate with a BME280 temperature and humidity sensor module connected to the bus socket.

```c
#include <M5Stack.h>
#include <Wire.h>
#include <BME280.h>

BME280 bme;

void setup() {
  M5.begin();
  Wire.begin();
  bme.begin();
}

void loop() {
  float temp = bme.readTemperature();
  float hum  = bme.readHumidity();
  Serial.printf("Temperature: %.2fC, Humidity: %.2f%%
", temp, hum);
  delay(1000);
}
```

Example 3: Wi-Fi Connectivity with ESP8266

In this example, we'll use the M5 Stack PROTO Module with Extension & Bus Socket to connect to a Wi-Fi network using an ESP8266 microcontroller.

```c
#include <M5Stack.h>
#include <WiFi.h>

const char ssid = "your_wifi_ssid";
const char password = "your_wifi_password";

void setup() {
  M5.begin();
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to Wi-Fi...");
  }
  Serial.println("Connected to Wi-Fi");
  Serial.println("IP address: ");
  Serial.println(WiFi.localIP());
}

void loop() {
  // Your code here
}
```
