NanoH2 Blue LED Light related APIs and example programs.

Example Program

Build Requirements

  • M5Stack Board Manager version >= 3.2.5
  • Development Board Option = M5NanoH2
cpp
1 2 3 4 5 6 7 8 9 10 11 12 13 14
#define BLUE_LED_PIN 4

bool blue_ledState = false;

void setup() {
  Serial.begin(115200);
  pinMode(BLUE_LED_PIN, OUTPUT);
}

void loop() {
  blue_ledState = !blue_ledState;
  digitalWrite(BLUE_LED_PIN, blue_ledState);
  delay(1000);
}

This program will control the blue LED on the device to blink at a 1-second interval, which can be used for status indication or debugging:
