I/O Error when objects are closer than approximately 10cm #23

Closed Reuspa closed 4 years ago

Reuspa commented 4 years ago

Hello, i got 3 amg8833 running with a TCA9548A I2C Multiplexer. it works fine until something comes closer than 10cm in front off one off the Sensors, then i get a OSError: [Errno 121] Remote I/O error. Any advice?

Can you recreate the issue with a single AMG8833 (no multiplexer) running the example program? https://github.com/adafruit/Adafruit_CircuitPython_AMG88xx/blob/master/examples/amg88xx_simpletest.py

when I run the example program with a single AMG8833, I get one of two errors 1:OSError: [Errno 121] Remote I/O error or 2: ValueError: No I2C device at address: 69. When I i2cdetect the i2cport changes. Bildschirmfoto von 2020-01-14 11-44-41

this happens with all three sensors i got. Most post say its probably the wiring, but i change the wires multiple times with new ones and i still get the same errors.

yeah this is almost certainly something with the wiring

I am using new wires straight out of the box. I changed the raspberry I am using and still I get the same errors. but thank you guy for answering. I will post in forums.
