YD-EPS32-23 2022-V1.3 Development Board RGB LED Not working

[amin-is]

Can you give an example code for this board RGB LED blinking OR NeoPixel example code

You should have purchased pirated hardware, but I can provide you with technical support.

W2812 Micropython CODE： from machine import Pin from neopixel import NeoPixel

ESP32-S3 48PIN ESP32-C3 8PIN ESP32 16PIN ESP32-S2 18PIN

pin = Pin(48, Pin.OUT) np = NeoPixel(pin, 1) np[0] = (10,0,0) #R B G max 255 255 255 np.write() r, g, b = np[0]

Can you give me arduino c language example. I have purchase a board when backside printed was only Board model, version and your web address and no any others information like this board. May be this board is copy..

@amin-is Hey guy，I have the same problem but I have fixed it，your board may be a knockoff，please see #1 , and this is my program to blink RGB using arduino。

#include <Arduino.h>
#include <FastLED.h>

#define LED_PIN 48
#define LED_NUMS 1

CRGB leds[LED_NUMS];

void setup() {
  Serial.begin(115200);
  FastLED.addLeds<NEOPIXEL, LED_PIN>(leds, LED_NUMS);
}

void loop() {
  leds[0] = CRGB(255, 0, 0);
  FastLED.show();
  Serial.print("RED \n");
  delay(1000);
  leds[0] = CRGB(0, 255, 0);
  FastLED.show();
  Serial.print("Green \n");
  delay(1000);
  leds[0] = CRGB(0, 0, 255);
  FastLED.show();
  Serial.print("Blue \n");
  delay(1000);
}

of course it work correctly!

你购买的板子可能为山寨板子，注意通信线路是否连接

F.Y.I. This board has a solder jumper marked RGB right next to the RBG LED which you have to short with a blob of solder and then the standard RGB Arduino sample code will work. The RGB led is connected to GPIO pin 38 and I guess the jumper is there in case you want to use this pin for a different purpose.
