core panic when initialized lcd and adafruit neopixel

[dawncold]

Describe the bug

I connected two RGB units with M5Atom, initiationly I'd like to use both internal LCD and RGB units together, but I found if I initialize the internal LCD(the last parameter of M5.begin(true, false, true);), it can not work with neopixel.

When I use parameterless begin, that means do not initialize LCD, it works fine.

To reproduce

M5Atom connects with a RGB unit, compile and upload it to M5Atom, click the button, leds should be lighten.

#include <M5Atom.h>
#include <Adafruit_NeoPixel.h>

int current_led_index = 0;
#define PIN       26  //定义NeoPixel的控制引脚
#define NUMPIXELS 6  //定义NeoPixel控制灯灯数量
Adafruit_NeoPixel pixels = Adafruit_NeoPixel(
    NUMPIXELS, PIN,
    NEO_GRB + NEO_KHZ800);  // set number of LEDs, pin number, LED type.
                            // 设置灯的数量,控制引脚编号,灯灯类型

void setup() {
  M5.begin(true, false, true);
  // randomSeed(analogRead(0));
  pixels.begin();
  pixels.setBrightness(50);
}

void loop() {
  M5.update();
  if (M5.Btn.wasReleased()) {
    uint8_t random_r = random(256);
    uint8_t random_g = random(256);
    uint8_t random_b = random(256);
    Serial.print("set led ");
    Serial.print(current_led_index);
    Serial.print(" to color: 0x");
    Serial.print(random_r, HEX);
    Serial.print(random_g, HEX);
    Serial.println(random_b, HEX);
    
    pixels.clear();
    pixels.setPixelColor(current_led_index, random_r, random_g, random_b);
    pixels.show();
    delay(50);

    current_led_index = (current_led_index + 1) % NUMPIXELS;
  }
}

Expected behavior

do not panic
