OctoPrint-PCA9685LEDStripControl

OctoPrint plugin that intercepts M150 GCode commands and controls LEDs connected to PCA9685 over I2C. Forked to add support to connect to a desktop PC through I2C on an FT232H. Also updated the code to work with newer releases of Octoprint. This does not work in python 2 at all. Tested on Python 3.10 and higher.

    M150 R U B      ; Turn LED white
    M150 W          ; Turn LED white if using RGBW strips (optional)
