NodeMCUCode Examples### Example 1: Wi-Fi Connection and HTTP Request using MicroPythonThis example demonstrates how to connect to a Wi-Fi network and send an HTTP request using MicroPython:
```python
import network
import urequests# Initialize Wi-Fi
wlan = network.WLAN(network.STA_IF)
wlan.active(True)# Connect to Wi-Fi network
wlan.connect('your_ssid', 'your_password')while not wlan.isconnected():
passprint('Connected to Wi-Fi network')# Send HTTP request
response = urequests.get('http://example.com')
print(response.text)
```
### Example 2: I2C Communication with a BME280 Sensor using C/C++This example demonstrates how to use the Wio Link board to communicate with a BME280 temperature and humidity sensor using I2C protocol:
```c
#include <Wire.h>#define BME280_ADDRESS 0x76void setup() {
Serial.begin(115200);
Wire.begin();// Initialize BME280 sensor
Wire.beginTransmission(BME280_ADDRESS);
Wire.write(0xF4); // Register address for temperature and humidity
Wire.endTransmission();delay(10);
}void loop() {
Wire.beginTransmission(BME280_ADDRESS);
Wire.requestFrom(BME280_ADDRESS, 6); // Read 6 bytes of dataint temp = Wire.read() << 8 | Wire.read();
int humidity = Wire.read() << 8 | Wire.read();
int pressure = Wire.read() << 16 | Wire.read() << 8 | Wire.read();Serial.print("Temperature: ");
Serial.print(temp / 16.0);
Serial.println(" Celsius");Serial.print("Humidity: ");
Serial.print(humidity / 16.0);
Serial.println(" %");Serial.print("Pressure: ");
Serial.print(pressure / 16.0);
Serial.println(" hPa");delay(1000);
}
```
### Example 3: LED Control using NodeMCUThis example demonstrates how to use the Wio Link board to control an external LED using NodeMCU:
```lua
-- Connect to Wi-Fi network
wifi.setmode(wifi.STATION)
wifi.sta.config("your_ssid", "your_password")
wifi.sta.connect()-- Wait for Wi-Fi connection
tmr.alarm(1, 1000, 1, function()
if wifi.sta.status() == wifi.STA_GOTIP then
tmr.stop(1)
print("Connected to Wi-Fi network")
end
end)-- Define LED pin
local ledPin = 2-- Initialize LED pin as output
gpio.mode(ledPin, gpio.OUTPUT)-- Toggle LED every second
tmr.alarm(2, 1000, 1, function()
gpio.write(ledPin, gpio.HIGH)
tmr.delay(500000)
gpio.write(ledPin, gpio.LOW)
end)
```
These examples demonstrate the versatility and ease of use of the Wio Link Wireless Development Board in various IoT applications.
