Unit PoE-P4 IR 红外发送相关库与案例程序。
#include <IRremote.hpp>
#include <M5Unified.h>
#define IR_SEND_PIN 14
// Demo parameters for NEC protocol
uint16_t address = 0x0000; // Starting device address
uint8_t command = 0x55; // Starting command value
uint8_t repeats = 0; // Number of repeat transmissions
void setup() {
M5.begin(); // Initialize M5Stack device
Serial.begin(115200); // Start serial communication at 115200 baud
delay(200); // Wait for serial port to stabilize
Serial.println("Unit PoE-P4 IRremote example");
// Initialize IR communication
IrSender.begin(DISABLE_LED_FEEDBACK); // Initialize IR sender without LED feedback
IrSender.setSendPin(IR_SEND_PIN); // Assign transmitter pin
Serial.printf("IR Send Pin: %d\n", IR_SEND_PIN);
delay(500); // Wait for hardware components to stabilize
}
void loop() {
// Send infrared signal using NEC protocol
Serial.printf("Send NEC: addr=0x%04x, cmd=0x%02x\n", address, command);
IrSender.sendNEC(address, command, repeats);
// Update transmission parameters for next cycle
address += 0x0001; // Increment device address
command += 0x01; // Increment command code
repeats = 0; // Disable repeat frames (set >0 to test repeats)
delay(2000);
}Unit PoE-P4 每两秒发送一次 NEC 红外信号,地址(Address)和命令(Command)分别从 0x0000 和 0x55 开始递增,可以使用支持 NEC 协议的红外接收设备进行接收验证。
