<![CDATA[DLight keeps giving max value]]>I have a brand new DLight. I used the M5Stack example code but all I get is the max value of the sensor, even when I cover the sensor. I tried all 6 modes. I also searched the internet but couldn't find any solution. I added a counter to the example. Here is my code:

#include <M5Atom.h>
#include <M5_DLight.h>

M5_DLight sensor;
uint16_t lux;
uint16_t counter = 0;

void setup() {
    M5.begin(true, true, true);
    Serial.println("Sensor begin.....");
    sensor.begin();

    // CONTINUOUSLY_H_RESOLUTION_MODE
    // CONTINUOUSLY_H_RESOLUTION_MODE2
    // CONTINUOUSLY_L_RESOLUTION_MODE
    // ONE_TIME_H_RESOLUTION_MODE
    // ONE_TIME_H_RESOLUTION_MODE2
    // ONE_TIME_L_RESOLUTION_MODE
    sensor.setMode(CONTINUOUSLY_H_RESOLUTION_MODE);
}

void loop() {
    M5.dis.fillpix(0x00ff00);
    lux = sensor.getLUX();
    Serial.printf("lux: %d\n", lux);
    counter = counter + 1;
    Serial.printf("Counter: %d\n", counter);
    delay(200);
}

This is the only output I get:

Counter: 32
lux: 65535
Counter: 33
lux: 65535
Counter: 34
lux: 65535
Counter: 35
lux: 65535
Counter: 36
lux: 65535
Counter: 37

Does anyone have an idea what I'm doing wrong?
