I'm having problems getting the Qwiic LED Stick up and running with Artemis running Arduino. The LED Stick works great with Python on Raspberry Pi, Adafruit QTPY Samd21, LoRa Pro RF, ESP32 boards but fails with Artemis nano, Artemis ATP, and the Apollo3 LoRa Thing Plus. It appears to be a communication problem but example 10 from the LED Stick was able to show many available i2c addresses including default (0x23). Just curious if anyone has some ideas as I'm kinda stuck. Thanks.

Hi @BarryAllen,

I guess you are using v2.1.1 of the Apollo3 (Artemis) boards in Arduino? Please try v2.1.0 and see if that makes a difference.

The ATtiny on the LED Stick will use I2C clock stretching, and the Artemis does not enjoy that - especially in v2.1.1.

Best wishes,
