I recently bought the SparkFun AS7262 Spectral Sensor for visible light.
I’m not using the Qwiic cabling as detailed in SparkFun’s hookup guide(https://learn.sparkfun.com/tutorials/as726x-nirvi?_ga=2.46616111.944092787.1515347549-1106913075.1512055668), I’m using jumper cables through a breadboard.
It’s a 3v3 board that uses the I2C protocol (by default). I’m attempting to use it with the Arduino Uno (which uses 5v logic) so I’ve wired it through the Adafruit I2C friendly logic level converter.
The only response I can get from the sensor is an I2C error (using the SparkFun library (link is on the hookup guide page) and SparkFun’s minimal code example (also on the hookup guide page)).
I have tripled checked the wiring and used a multimeter to check continuity. I’ve also tried replacing the spectral sensor with an Adafruit humidity sensor (also 3v3 and I2C), and the humidity sensor works perfectly. I’ve tried using a simple script to detect attached I2C devices, but it fails to find anything when the spectral sensor is attached.
Can anyone help me diagnose what is going on with this sensor?
