Example Code 1: LoRa Communication using Arduino IDE
In this example, we will demonstrate how to use the SX1262 LoRa module to send and receive data between two V3 boards.
Sender Code:
```c
#include <SPI.h>
#include <LoRa.h>
#define SCK 5
#define MISO 19
#define MOSI 27
#define SS 18
#define RST 14
LoRa lora = LoRa(SCK, MISO, MOSI, SS, RST);
void setup() {
Serial.begin(9600);
lora.begin();
lora.setFrequency(868E6);
lora.setSpreadingFactor(7);
lora.setBandwidth(250E3);
lora.setCodingRate(5);
}
void loop() {
String message = "Hello, LoRa!";
lora.beginPacket();
lora.print(message);
lora.endPacket();
delay(1000);
}
```
Receiver Code:
```c
#include <SPI.h>
#include <LoRa.h>
#define SCK 5
#define MISO 19
#define MOSI 27
#define SS 18
#define RST 14
LoRa lora = LoRa(SCK, MISO, MOSI, SS, RST);
void setup() {
Serial.begin(9600);
lora.begin();
lora.setFrequency(868E6);
lora.setSpreadingFactor(7);
lora.setBandwidth(250E3);
lora.setCodingRate(5);
}
void loop() {
int packetSize = lora.parsePacket();
if (packetSize) {
String message = "";
while (lora.available()) {
message += (char)lora.read();
}
Serial.println(message);
}
delay(1000);
}
```
Example Code 2: Wi-Fi Connectivity using MicroPython
In this example, we will demonstrate how to connect to a Wi-Fi network using MicroPython on the V3 board.
MicroPython Code:
```python
import machine
import network
wlan = network.WLAN(network.STA_IF)
wlan.active(True)
wlan.connect("your_wifi_ssid", "your_wifi_password")
while not wlan.isconnected():
machine.sleep(100)
print("Connected to Wi-Fi!")
print("IP Address:", wlan.ifconfig()[0])
```
Example Code 3: OLED Display using Arduino IDE
In this example, we will demonstrate how to use the 0.96-inch OLED display to display a simple text message.
Arduino Code:
```c
#include <U8x8lib.h>
U8X8_SSD1306_096_64 u8x8(U8X8_PIN_NONE);
void setup() {
u8x8.begin();
u8x8.setFlipMode(1);
u8x8.setFont(u8x8_font_amatic_b);
}
void loop() {
u8x8.clear();
u8x8.setCursor(0, 0);
u8x8.print("Hello, OLED!");
u8x8.refresh();
delay(1000);
}
```
