Hi I am having problems getting my Enviro to work with a Pi Zero WH which appears to otherwise work OK. I have used a new up to date installation of Symbian and followed your instructions for installing the software for the Enviro but this throws up a number of errors. Trying to run the Python de…

I have tried both methods of installation with similar results. I get a series of error messages which endwith the following No package ‘libffi’ found c/_cffi_backend.c:15:10: fatal error: ffi.h: No such file or directory #include <ffi.h> ^~~~~~~ compilation terminated. error: Setup script exi…

I have also run a simple python test and do see the I2c active: #!/usr/bin/env python import smbus bus = smbus.SMBus(1) # 1 indicates /dev/i2c-1 for device in range(128): try: bus.read_byte(device) print(hex(device)) except: # exception if read_byte fails pass python3 i2ctes…

I have tried the same and only get 0x23 & 0x76 but I presume that is because I have an Enviro not an Enviro+ so fewer sensors.

My search for libffi took me here, not sure if it helps though. [image] libffi/libffi A portable foreign-function interface library. Contribute to libffi/libffi development by creating an account on GitHub.

i2cdetect -y 1 is what you can run from terminal. For the + it’s 0x49: ADS1015 0x76: BME280 0x23: LTR559

One thing you can do is report this on Pimoroni’s GitHub Page for the Enviro / Enviro+, in the issues section. [image] pimoroni/enviroplus-python Python library for the Enviro+ environmental monitoring board - pimoroni/enviroplus-python Running i2c detect is a…

Many thanks for your help. I have finally got it working by installing the missing libffi module with sudo apt-get install libffi-dev having done that the enviroplus-python package installs without any error messages and after rebooting the demo programmes run as expected.

That’s good to hear. Best guess is the owner of the libffi repository has moved things around or changed something that has broken the Pimoroni installer.

Hi all. I’m struggling with this on my new enviro and enviro+ . Have you found any way forward to get these working? Thanks.

I had a look at it and found it all a bit beyond my skill level but it may provide some help.
