error running pygamer thermal camera project

Post by acordeon »

Hi newbie here looking for help. Not sure this is even the right forum to post in -- feel free to redirect me if not.

I'm trying to help my son get this project working: https://learn.adafruit.com/improved-amg ... a/overview

We've done all the install steps: installed CircuitPython, installed the adafruit library bundle, uploaded the project code files, and plugged the IR camera chip into the pygamer. But it's not running. When we boot it up, we get the following error:

Code: Select all

File "adafruit_amg88xx.py", line 131, in __init__ Value Error: No I2C device at address: 0x69
Does this indicate there's something wrong with the feather board, or that it's not connected properly? Or might it indicate a problem with the code environment?

Thanks for any help w/ troubleshooting we should do!

Can you post a clear closeup (relatively) of your soldering of the headering onto the AMG8833 board?

We did not solder it. My son thought it might not be necessary to solder it and just connected all the pins without solder. Is that a bad assumption? Is this going to need to be soldered to work, even temporarily?

It is absolutely necessary to solder the header pins into the FeatherWing. There is no guarantee of a reliable electrical connection without it.

This isn't the same FeatherWing, but the process is the same: https://learn.adafruit.com/adafruit-128 ... g/assembly. See https://learn.adafruit.com/adafruit-gui ... -soldering and https://learn.adafruit.com/collins-lab-soldering for tips/advice on soldering.
