Sorry, I couldn't find any breakouts!

Support

I’ve got an I2C/SPI Breakout Garden on a Pi 3 running Buster Lite.

I plugged everything in an ran the installer, but it doesn’t appear to be detecting any of the breakouts.
I’ve installed python-pip and python-smbus since they’re not included with Lite.
I also enabled I2C and SPI in raspi-config

I installed the library for the LCD and tried some of the examples, but nothing happened.

It’s starting to feel like maybe the Garden is faulty?

An abridged log of what I tried:

$ sudo ./breakout-garden-master/install.sh
  Breakout Garden requires I2C. We've enabled it for you.

A lot of those breakouts have a message on their product page saying
“Our software does not support Raspbian Wheezy.”

Might be time to switch to Buster.

Sorry, I did mean Buster. It was a fresh install from a fresh download this morning.
🤦‍♂️

Is the hat firmly pressed down / firmly attached to the Pi’s GPIO?

I’ve just tried the same (Raspbian Lite, i2c+spi garden) but with only the SGP30 sensor.

I thought I’d try Raspbian Full and that did the same.

Playing with i2cdetect -y 1, I noticed that it seems to show a device number 0x58 and breakouts.config used by the autodetect.py of breakout-gardens code doesn’t have an entry for 0x58.

I tried the sgp30 example from https://github.com/pimoroni/sgp30-python (also needs pip install smbus2) and that appears to work and notice me breathing on the sensor.

Buster Lite, seems to be missing some stuff that was in previous Lite releases of Raspbian?

I have some breakouts on the way so I’ll be going down that road in the next day or two. I didn’t order the pHat or Hat though. mine will be connected directly. I won’t be using the light version of Raspbian either, I always use the with desktop version.

EDIT: Forgot to mention, I have two BME680’s wired up and working. Pi A+'s running Jessie. Buster wasn’t released when I set them up. For what its worth, I don’t remeber having any install issues.

I am incredibly embarrassed to say that I had all my Breakouts in backwards. No idea how I managed to do that. 🤦‍♂️

Thanks all for your help

Stuff like that happens to the best of us. The way the hat is designed they are protected against that so no harm done. Other than some head scratching etc.
