I am using this lib and example:<br />
<a href="https://github.com/m5stack/M5-DLight/blob/master/examples/Unit_DLight_M5Core2/Unit_DLight_M5Core2.ino" target="_blank" rel="noopener noreferrer nofollow ugc">https://github.com/m5stack/M5-DLight/blob/master/examples/Unit_DLight_M5Core2/Unit_DLight_M5Core2.ino</a><br />
The reading is always 65535, and seems like the I2C port doesn't initiate!<br />
I connected the sensor on a general Arduino board and was reading the data so it is definitely something with the Core2 not reading the I2C portA.<br />
I ve also tried sensor.begin(&amp;Wire, 32, 33) to explicitely specify the external I2C on Core 2 but didn't work<br />
Would love some help!</p>
