Imagine RGB LED strips at the sides of your TV, which reacts on whats happening in your favourite video game or film - this is what this project is trying to accomplish.
The idea is to capture screen and convert (downsample) captured image to Nx2 array of rgb data, where N is number of LEDs at each side of screen. Next its going to be send over COM port to Arduino or similar microcontroller, which will handle addressable RGB strip.
-
Create the rgbLBC object, passing number of LEDs and FPS you want to achieve. IMPORTANT: LED number should be the SIDE number of LEDs.
-
If you want to send data via serial port you should use
setup_serial()method and pass serial port name and baud rate.
INFO: Current version of the Arduino code sends "<Arduino is ready>" string when it is ready to handle incoming data, so you should handle waiting for that signal or: from rgbLBC.serial_utilities import waitForArduino
- Finally use
self.start()method to start capturing the screen (and sending rgb data through serial) self.stop()should be used to properly stop capturing and close serial connection
- using fast screenshot capturing library d3dshot
- downsampling using PIL.Image.resize() with Image.BOX resampling algorithm
- class iherits now directly from D3DShot; easier access to methods and attributes, while maintaining singleton of parent class
- base class functionalities
- threaded start() method
- serial communication - sending RGB values through serial port
- Arduino code - receiving values
- Arduino code - FastLED part - setting up LEDs with received data
- timing - is current code fast enough to achieve at least 25 FPS?
- package files: setup.py etc
As for now, d3dshot needs pillow version 7 to work, and latter does not support newest Python, so this project is coded under Python 3.7
- GUI
