根据板子的资料我们可以查到 ESP32-S3-Zero 板载了一颗 WS2812B LED,这颗 LED 的引脚是 GPIO 21,我们可以通过以下代码来驱动这颗 LED: intWS2812_Count =1;intWS2812_Pin =21;varleddev =newWs2812b(WS2812_Pin, WS2812_Count);BitmapImageimg = leddev.Image;img.SetPixel(0,0,Color.Red);leddev...
// the setup function runs once when you press reset or power the board void setup() { // initialize digital pin LED_BUILTIN as an output. pinMode(PULSE, OUTPUT); Serial.begin(115200); } int loop_count=0; // the loop function runs over and over again forever void loop() { digita...
由于我的esp32的板载LED灯的pin number是2,修改#define LED_PIN 13为2。中断pin 2修改为#define INTERRUPT_PIN 13 //修改后 #define INTERRUPT_PIN 13 // use pin 2 on Arduino Uno & most boards #define LED_PIN 2 // (Arduino is 13, Teensy is 11, Teensy++ is 6)...

Demonstrates usage of onboard RGB LED on some ESP dev boards. Calling digitalWrite(RGB_BUILTIN, HIGH) will use hidden RGB driver. RGBLedWrite demonstrates controll of each channel: void neopixelWrite(uint8_t pin, uint8_t red_val, uint8_t green_val, uint8_t blue_val) ...

it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to the correct LED pin independent of which board is used. If you want to know what pin the on-board LED is connected to on your Arduino model, check the Technical Specs of your board at: ...
查原理图可知板载LED有2个,分别为IO38和IO39 将以下代码填入至main.cpp 点击查看代码 highlighter- Arduino #include <Arduino.h> // blink led void blink(int pin, int delay_ms) { digitalWrite(pin, HIGH); delay(delay_ms); digitalWrite(pin, LOW); delay(delay_ms); } const int led_pin_1 ...

we are using the ESP32-S2 DevKit M1 v1.0 (ESP-S2-MINI-2; `XXN4R2`) and are encountering strange behavior on some of them. Instead of the on-board WS2812 Led going white when told so it will show red. All of the other primary colors seem to work (red, blue, green). To rule...
