A Scratch extension and python-based server for WS2801 led strips connected to Raspberry Pi

ws2801scratch's Issues

Merge and rename to ws28xx

Now that the Python server process for WS2811/WS2812 strips has been added, both WS2801 and WS2811/WS2812 scripts should be merged into a single Python script for easier maintenance. The whole project should be renamed to ws28xx.

Reversed Green and Blue variables in some of the server code

Hi,
Thanks for putting this project together. I am teaching some 5th grade students how to interact with a strand of WS2801 lights for a LED sign project at our school. I found this project, and it's perfect to get them up and running using scratch.

One issue I found is that normally we reference RGB as "red, green, blue" when making pixel change within the adafruit libraries. In some of the lines of server code, the green and blue variables are transposed, which makes the scratch interface set the wrong colors.

Line 72 pixels.set_pixel_rgb(pix, red, blue, green)
Line 75 pixels.set_pixel_rgb(pix, red, blue, green)
Line 85 color=Adafruit_WS2801.RGB_to_color(red,blue,green)

All these need to read (red, green, blue) for correct color selection.
