Arduino Quick Start
Air Quality button input related APIs and example program.
#include <M5Unified.h> void setup() { auto cfg = M5.config(); cfg.serial_baudrate = 115200; M5.begin(cfg); M5.Lcd.clear(); M5.Lcd.setTextSize(2); M5.Lcd.setCursor(0, 0); M5.Lcd.println("M5AirQ Button Test");} void loop() { M5.update(); // Detect BtnA (GPIO0) click if (M5.BtnA.wasClicked()) { Serial.println("AirQ BtnA clicked"); M5.Lcd.println("BtnA clicked"); } // Detect BtnB (GPIO8) click if (M5.BtnB.wasClicked()) { Serial.println("AirQ BtnB clicked"); M5.Lcd.println("BtnB clicked"); } delay(10);}
After uploading, press the buttons to see the following effect:
The button functionality uses the Button_Class
from the M5Unified library. For more button-related APIs, please refer to the documentation below:
