paj7620 代码

PAJ7620是一种手势识别控制器芯片，可以通过手势控制实现各种功能。以下是一个简单的PAJ7620代码示例，通过Arduino控制PAJ7620传感器进行手势识别和控制。

#include <Wire.h>

#define PAJ7620_ADDR 0x73
#define GES_RIGHT_FLAG      1
#define GES_LEFT_FLAG       2
#define GES_UP_FLAG         3
#define GES_DOWN_FLAG       4
#define GES_FORWARD_FLAG    5
#define GES_BACKWARD_FLAG   6
#define GES_CLOCKWISE_FLAG  7
#define GES_COUNT_CLOCKWISE_FLAG 8
#define GES_WAVE_FLAG       9

void setup() {
  Wire.begin();
  Serial.begin(9600);
  delay(100);
  pinMode(2, INPUT);
  delay(100);
  paj7620SelectBank(0);
  paj7620Init();
}

void loop() {
  int data = paj7620ReadRegister(0x43, 1);
  if (data == GES_RIGHT_FLAG) {
    Serial.println("Right");
    // 执行右滑动手势对应的操作
  } else if (data == GES_LEFT_FLAG) {
    Serial.println("Left");
    // 执行左滑动手势对应的操作
  }
  // 其他手势判断和相应操作
  delay(100);
}

void writeRegister(int addr, int cmd) {
  Wire.beginTransmission(PAJ7620_ADDR);
  Wire.write(addr);
  Wire.write(cmd);
  Wire.endTransmission();
  delay(10);
}

void paj7620SelectBank(int bank) {
  writeRegister(0xEF, bank);
}

void paj7620Init() {
  paj7620SelectBank(0);
  writeRegister(0x73, 0x20);
  writeRegister(0x64, 0X00);
  writeRegister(0xEF, 0x00);
  writeRegister(0x3F, 0x03);
  writeRegister(0x65, 0x00);
  writeRegister(0x6A, 0x00);
  writeRegister(0x6B, 0x00);
  writeRegister(0x6C, 0x05);
  writeRegister(0x6D, 0x87);
  writeRegister(0x6E, 0x32);
  writeRegister(0x72, 0x01);
  writeRegister(0x73, 0x01);
  writeRegister(0x70, 0x42);
  writeRegister(0x71, 0x00);
  writeRegister(0x72, 0x01);
  writeRegister(0x73, 0x01);
  writeRegister(0x70, 0x42);
  writeRegister(0x71, 0x00);
  writeRegister(0x21, 0x01);
  writeRegister(0x21, 0x00);
}

int paj7620ReadRegister(int addr, int n) {
  int data = 0;
  Wire.beginTransmission(PAJ7620_ADDR);
  Wire.write(addr);
  Wire.endTransmission();
  Wire.requestFrom(PAJ7620_ADDR, n);
  if (Wire.available()) {
    data = Wire.read();
  }
  return data;
}

这段代码是一个基本的PAJ7620手势识别控制器的Arduino示例。它对PAJ7620传感器进行了初始化，并在循环中不断读取手势数据，然后执行相应的操作。可以根据具体的应用场景，修改代码中的操作部分，实现不同的手势控制功能。
