Control your neopixels from your PC!

Installation

cargo add neobridge-rust

Setup (board)

To start controlling neopixels directly from your PC, you have to setup your circuitpython board to receive serial commands. This is already programmed in the code.py script. Follow the steps below.

1. Download code.py
2. Move to the circuitpython board (RP2040 is officially supported)
3. You will need to edit code.py to fit your setup! (Number of LEDs, Pin location, Order)
4. Run the script. The script will run every bootup.

Setup (PC/Linux/MacOS)

Now that the board is ready for serial communication, you can now control it from your PC directly. This lets you program a lot of cool lighting effects! The example below creates a 'loading' bar like effect.

use neobridge_rust::{Neobridge, RGB};

fn main() {
    let mut neobridge = Neobridge::new("COM3", 30);
    neobridge.set_all(RGB(0, 0, 0));
    neobridge.show();

    let mut i = 0;
    loop {
        if (i == 30) {
            i = 0;
        }

        neobridge.set_one(RGB(255, 255, 255), i);
        neobridge.show();
        std::thread::sleep(std::time::Duration::from_millis(50));

        neobridge.set_all(RGB(0, 0, 0));

        i += 1;
    }
}

Before you can start controlling from PC, you have to enter the location of your board.

• On Windows, this is usually under a name such as COM3, this can be different.
• On Linux, it looks like /dev/ttyACM0
• On MacOS, the name looks like /dev/tty.usbmodem1d12

These names can be different! Make sure to find the right one for the board!
