Hello there !
I’m using one WS2812 connected to GPIO7 in a AB02A… I1m tryibg the WS2812.ino example, but the led or just flash green or flash random color… can some one help me?
Trouble using WS2812 on HTCC-AB02A
Im using this code:
#include “CubeCell_NeoPixel.h”
CubeCell_NeoPixel pixels(1, GPIO4, NEO_GRB + NEO_KHZ800);
void setup() {
pinMode(Vext, OUTPUT);
digitalWrite(Vext, LOW); //SET POWER
pixels.begin(); // INITIALIZE NeoPixel strip object (REQUIRED)
pixels.clear(); // Set all pixel colors to 'off'
}
uint8_t r = 60;
void loop() {
pixels.setPixelColor(0, pixels.Color(r, 0, 0));
pixels.show(); // Send the updated pixel colors to the hardware.
delay(500); // Pause before next pass through loop
pixels.setPixelColor(0, pixels.Color(0, 0, 0));
pixels.show(); // Send the updated pixel colors to the hardware.
delay(500); // Pause before next pass through loop
}
I’ve posted this video to share my problem:https://youtube.com/shorts/wagN45neKYw?si=e1ZiAKVqCqrgBX64

Perhaps this will be helpful to you
I have the same Problem using WS2812 arrays with cubecell AB01-V2. The first LED 0 lits randomly green with full brightness. All other LED’s behind are working correctly.
