No readings from grideye sensor w/ ESP32

Post by Rashmeed » Sun Jan 20, 2019 7:34 am

I have an ESP32 thing (DEV-13907) with a Grid-EYE Infrared Array Breakout (AMG8833) sensor. The two are connected using a Qwiic Cable - Breadboard Jumper (4-pin) with:

Black wire: GND
Red wire: 3v3
Yellow wire: 22
Blue wire: 21

The device is detected using a simple scanner: "I2C device found at address 0x69" however I'm not getting any readings from the device when trying to use the given examples for GRIDEYE.

Not sure if this is an issue with the ESP32 or the sensor or the SparkFun_GridEYE_Arduino_Library; or am I missing something?

For reference, here's the example I'm trying to run: https://github.com/sparkfun/SparkFun_Gr ... rature.ino

and I'm just getting the output:

Thermistor Temperature in Celsius: 0.00
Thermistor Temperature in Fahrenheit: 32.00
Thermistor Temperature register contents: 0

...which indicates to me values aren't being received from the sensor?

Any help would be appreciated.

Solved, updating the esp32 library from 1.0.0 to 1.0.1 seemed to fix it.
