ESP32 keep rebooting #356

Open KaTOxDev opened 3 weeks ago

KaTOxDev commented 3 weeks ago

Hello , i use ESP32 with this example : `#include

define LED_COUNT 120

define LED_PIN 17

define TIMER_MS 5000

// Parameter 1 = number of pixels in strip // Parameter 2 = Arduino pin number (most are valid) // Parameter 3 = pixel type flags, add together as needed: // NEO_KHZ800 800 KHz bitstream (most NeoPixel products w/WS2812 LEDs) // NEO_KHZ400 400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers) // NEO_GRB Pixels are wired for GRB bitstream (most NeoPixel products) // NEO_RGB Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2) // NEO_RGBW Pixels are wired for RGBW bitstream (NeoPixel RGBW products) WS2812FX ws2812fx = WS2812FX(LED_COUNT, LED_PIN, NEO_RGB + NEO_KHZ800);

unsigned long last_change = 0; unsigned long now = 0;

void setup() { ws2812fx.init(); ws2812fx.setBrightness(255); ws2812fx.setSpeed(1000); ws2812fx.setColor(0x007BFF); ws2812fx.setMode(FX_MODE_STATIC); ws2812fx.start(); }

void loop() { now = millis();

ws2812fx.service();

if(now - last_change > TIMER_MS) { ws2812fx.setMode((ws2812fx.getMode() + 1) % ws2812fx.getModeCount()); last_change = now; } } `

when i set LED_COUNT to 120 i get this error and my ESP32 keep rebooting

`ERROR A stack overflow in task loopTask has been detected.

i try to set LED_COUNT to 30 and it work with no error . idk the limit of LED_COUNT

This seems to be a bug caused by how the Adafruit-NeoPixel library is programming the ESP32's RMT hardware when arduino-esp32 core v3.0 is installed. I'll look into this further, but in the meantime I would suggest using Board Manager to downgrade the arduino-esp32 core to version 2.0.17. That should get you up and running.

thank you 👍

Looks like this issue is already being discussed on the Adafruit_Neopixel GitHub repository: Adafruit_NeoPixel/issues/375 There's already a proposed fix and pull request, so it should be fixed soon.
