I’ve assembled, soldered, and flashed a raspberry pi zero w with all the correct OS and packages. I’ve been using the instruction guide found here: https://github.com/sandyjmacdonald/pimoroni_learning_materials/blob/master/twitter_scroll_phat.md
And it’s been going pretty well so far, up until the part where I run this code: “sudo python test-all.py”
From there, I get this error:
File “test-all.py”, line 10, in
File “build/bdist.linux-armv6l/egg/scrollphat/init.py”, line 60, in set_brightness
File “build/bdist.linux-armv6l/egg/scrollphat/init.py”, line 26, in _get_controller
File “build/bdist.linux-armv6l/egg/scrollphat/IS31FL3730.py”, line 21, in init
File “build/bdist.linux-armv6l/egg/scrollphat/IS31FL3730.py”, line 62, in set_mode
IOError: [Errno 121] Remote I/O error
I already checked to make sure my soldering job was solid, so I’m not sure where I went wrong with the code. Is there some sort of diagnostic I can run? I tried to skip that part and simply go straight to running the twitter app, but that has issues as well. I figure if I can solve this part of the problem, I have a better chance at having the rest of the code run smoothly as well. My ultimate goal is to get the Pimoroni to do the weather/Twitter ticker functions for my wife.
Thanks so much!
