Enabling I2C on Raspberry Pi - DJBuck - Mar-28-2019

Tried posting this to the Raspberry Pi forum, but the concept of "urgent" appears to carry no meaning with them.

https://learn.adafruit.com/adafruit-ccs811-air-quality-sensor/raspberry-pi-wiring-test

I have followed all instructions here exactly, all wiring and code, double and triple checked.

I get to the "Now you should be able to verify that the sensor is wired up correctly by asking the Pi to detect what addresses it can see on the I2C bus" section, but cannot get the 5A address, I just get an empty table.

What am I doing wrong?

You need to provide more information:
There aren't that many steps here.
  • Start from beginning, recording everything (in a separate text file).
  • Triple check wiring.
  • Copy any massages along the way and include those next to step where they occur.
  • Make sure all error messages are copied verbatim.
  • Post results
