案例程序

Arduino


#include <M5Stack.h>

#define JOY_ADDR 0x52 //define Joystick I2C address.  定义摇杆的I2C地址

void setup() {
  M5.begin();
  M5.Power.begin();
  M5.Lcd.setCursor(70, 0, 4);
  M5.Lcd.println(("Joystick Test"));
  dacWrite(25, 0);  //disable the speak noise.  禁用语音噪音
  Wire.begin(21, 22, 400000);
}

char data[100];
void loop() {
  static uint8_t x_data,y_data,button_data;
  Wire.requestFrom(JOY_ADDR, 3);  //Request 3 bytes from the slave device.  向从设备请求3个字节
  if (Wire.available()) { //If data is received.  如果接收到数据
    x_data = Wire.read();
    y_data = Wire.read();
    button_data = Wire.read();
    sprintf(data, "x:%d y:%d button:%d\n", x_data, y_data, button_data);
    Serial.print(data);

    M5.Lcd.setCursor(100, 50, 4);
    M5.Lcd.printf("X:%d      ",x_data);
    M5.Lcd.setCursor(100, 80, 4);
    M5.Lcd.printf("Y:%d      ",y_data);
    M5.Lcd.setCursor(100, 110, 4);
    M5.Lcd.printf("B:%d      ",button_data);
  }
  delay(200);
