Hardware revision is not supported for Raspbery pi 3

[karcio]

HI, I have the same problem like issue #342

Trying to run RotorHazard race tracker on raspberry pi 3
pi@delta5:~/RotorHazard/src/server $ python server.py
Configuration file imported

RuntimeError: ws2811_init failed with code -3 (Hardware revision is not supported)

I found that solution can be resolved as closed issue #342 but I have latest code and still this is happen.

You need to specify your hardware revision- a specific model of Pi (ie: 3B+) could have several revisions for reasons as simple as being manufacturered in a different location.

Run cat /proc/cpuinfo | grep Revision and paste the results here.

Also, if you're using neopixel.py (the Python examples in this repository) you're running deprecated, largely unsupported code. You should migrate to the Python bindings - https://github.com/rpi-ws281x/rpi-ws281x-python

Hi @Gadgetoid
Sure, sorry about that
pi@delta5:~ $ cat /proc/cpuinfo | grep Revision
Revision : a02083

So I cloned repo you point me then
pi@delta5:~ $ sudo pip uninstall rpi_ws281x
Uninstalling rpi-ws281x-1.0.0:

Proceed (y/n)? y

but now I can see other issue
pi@delta5:~/RotorHazard/src/server $ python server.py
Traceback (most recent call last):

ImportError: No module named neopixel

[Gadgetoid]

The neopixel module has been dropped. Use from rpi_ws281x import * instead.

Your Revision ID is awful close to the one merged here -#362 - and is, in fact, not currently supported by the codebase so rpi-ws281x will not work for you at all. Yet.

I'll get this Revision ID merged and another point release out, since there are a couple of changes to go with it.

[Gadgetoid]

Support should be available in versions >= 4.2.2

sudo pip install --upgrade rpi_ws281x
