A Pimoroni Plasma library for NodeJS
I developed this for working with another project and its feature set is fairly limited right now. Currently the only device supported is the Pimoroni Player X using USB serial connection. If someone comes along and needs a specific device please let me know, I'll try to add it.
I tried to replicate some of the structure and method signatures of the python library.
There are two ways to get a device object, auto connect or manual.
With this all you need to do is specify a formated connection string to the auto function and it will try to connect for you.
import { auto, PicadePlayerX } from 'plasma-lights';
/**
* The Player X and I assume other devices are not able to detect how many LEDs are connected.
* You will need to set them in the connection string.
* Also note that you can set any number but the Picade Plasma buttons have 4 LEDs per button and would
* recommend setting a multiple of 4 when using them.
*/
const NUM_PIXELS = 12;
/**
* Format for connection string
* [connection type]:[connection address][:...configuration values]
*/
const plasma = auto(`SERIAL:COM7:${NUM_PIXELS}`);
// attempts to hook before process exit to clear pixels
plasma.set_clear_on_exit(true)
// You can start talking to the plasma device as is
plasma.clear()
plasma.set_pixel(0, 255, 255, 255, 1)
// But I also made a helper library for the Player X when using the Plasma buttons
const playerX = new PicadePlayerX(plasma)
// This will set the first 4 addressed pixels to the same color
playerX.setButton(0, 255, 255, 255, 1)The connection method is the same but instead of COM7 use /dev/ttyACM0. Make sure to check your write permissions!
Similar to before but instead of providing a connection string you simply call the constructor for the type of connection you are creating.
import { PlasmaSerial } from 'plasma-lights'
const plasma = new PlasmaSerial("COM7")
...Support on linux- Support for other devices
