Prop Maker 3WATT LED

[dcaditz]

The sample code for the Prop Maker 3 Watt LED (link below) does not seem to work. I get an error on the line r, g, b = colorwheel(i):

TypeError: 'int' object is not iterable

It seems that colorwheel just returns an integer

Using circuitpython 7.1.1 on an M4 Express

Any suggestions?


Sample code is here (scroll down to the 3 Watt LED example):

Yes, colorwheel in rainbowio currently returns an int: 0xRRGGBB. You'll have to tear it apart to extract each byte:

Instead of

Code: Select all

r, g, b = colorwheel(i)

you can use

Code: Select all

c = colorwheel(i)
r = (c >> 16) & 0xFF
g = (c >> 8) & 0xfFF
b = c & 0xFF

Thank you. That explains it. I think there is a typo in the g line, though.

Ah, yes I didn't backspace over that lowercase f. Good catch.
