Raspberry Pi 3 A+ not supported?

[LongLane]

I am getting:

File "build/bdist.linux-armv7l/egg/neopixel.py", line 106, in begin
RuntimeError: ws2811_init failed with code -3 (Hardware revision is not supported)

It runs fine on a Zero or Pi2

I checked on the Raspberry Pi documentation regarding HW codes. In the past, they used sequential codes, whereas it has changed a while ago. The code for the 3A+ is 9020e0 (3B+ a020d3).

Looking at the code in ws2811.c, hwver >= 0x010 should be working, but it returns an error.

I suspect, that the hardware check needs to be brought in line with the new versioning system.

Thanks

It needs to be added to https://github.com/jgarff/rpi_ws281x/blob/master/rpihw.c

Thanks. I changed rpihw.c accordingly and created a pull request.
