This project is a plugin to pibooth that enables you to add neopixels to your project using the SPI bus on Raspberry Pi instead of the PWM bus. The benefits of using SPI over PWM are:
PiBooth is a fantastic project for creating your own Photobooth. I have built one using a Raspberry Pi and more details on my implementation to come. But I really wanted to use an Adafruit neopixel ring to implement things like:
I original followed the Adafruit Adafruit NeoPixel Python usage guide to get my neopixel ring setup. But then I ran into problems with the fact that the code has to run as the root user. I didn't want to do that for security reasons. So I decided to use the SPI bus instead which does not require root to use it.
# Path to custom plugin(s) not installed with pip (list of quoted paths accepted)
plugins = ["<your path to where you copied the file>/pibooth-neopixel_spi.py"]This is the actual PiBooth plugin and the only file you really need.
This is a handy file to demonstrate coding for the neopixels. This was originally from the Adafruit examples. But I added a 'countup' feature. This feature isn't used in pibooth-neopixel_spi.py but you could do if you have a use for it.
I can't remember where I found this, but it's useful for ensuring you have the colours setup correctly.
The plugin will automatically be included in your pibooth setup the next time you restart pibooth.
