Hat DLight Arduino 使用教程

#include <M5Unified.h>
#include <M5_DLight.h>

M5_DLight sensor;
uint16_t lux;       // store sensor reading

void setup() {
  // initializatize M5StickC-Plus2
  auto cfg = M5.config();
  M5.begin(cfg);
  Serial.begin(115200);
  Serial.println("Initializing DLight sensor...");
  delay(2000);

  // initialize sensor
  sensor.begin(&Wire, 0, 26);   // Hat DLight (SDA:G0, SCL:G26)
  sensor.setMode(CONTINUOUSLY_H_RESOLUTION_MODE);

  // setup display
  M5.Display.setRotation(1);  // depends on the direction of the StickC_Plus2 being held
  M5.Display.setTextColor(GREEN);
  M5.Display.setTextSize(2);

  Serial.println("StickC-Plus2 with DLight is ready!");
}

void loop() {
  M5.update();

  lux = sensor.getLUX();  // get sensor reading

  // display on StickC-Plus2's screen
  M5.Display.startWrite();
  M5.Display.setCursor(64,55);
  M5.Display.fillScreen(BLACK); // clear screen
  M5.Display.printf("Lux: %d\n", lux);

  // display on serial terminal
  Serial.printf("Light Intensity: %d lux\n", lux);

  delay(1000);
}
