I’ve just got an Enviro+ with the particulate matter sensor and unfortunately I can’t get the LCD display to work. Running the lcd.py example I get a tiny multi-coloured ring which you can just make out in the photo
new Pi Zero WH with latest raspbian os
Official raspberryPi power supply so power should be OK.
Enviro + Air Quality
PMS5003 Particulate Matter Sensor
Followed GitHub - pimoroni/enviroplus-python: Python library for the Enviro+ environmental monitoring board and Getting Started with Enviro+ - Pimoroni Yarr-niversity to install, configure and test the board.
The sensors appear to be working correctly in that I can obtain readings from the PMS and from the board (gas, temp, proximity, light). I have run the python examples.
The LCD backlight is coming on and off when the program finishes. The display displays a tiny multi-coloured ring when running lcd.py.
SPI is definitely enabled.
I have checked all the python libraries including the ST7735 library.
I’ve tried the enviro+ on a Pi4 and the results are the same. I ran the lcd.py in debug and added all the requested libraries until it ran without error.
