Serial Pixel

Ardunio library for controlling NeoPixel LEDs over serial.

Load onto your favorite arduindo and then control your pixels via serial.

Commands

Commands have the following form:

CTL	Payload	END
1 byte	0..N bytes	'\n'

Init Command

Either one of:

CTL	N	END
'I'	2 bytes	'\n'

or

CTL	N	C	END
'I'	2 bytes	2 bytes	'\n'

• N represents the number of pixels in hex (ie, 26 pixels is 1a)
• C (optional) are the config bytes in hex.
  • This is not necessary when your neopixel is GRB, but is for all other pixel types.

RGB Command

CTL	INDEX	RGB[0..N]	END
'S'	2 bytes	6xN bytes	'\n'

• INDEX represents the start LED index
• RGB[0..N] are 3-byte multiples of RGB values to apply to sequential LEDs.

HSV Command

CTL	INDEX	HSV[0..N]	END
'S'	2 bytes	6xN bytes	'\n'

• INDEX represents the start LED index
• HSV[0..N] are 3-byte multiples of HSV values to apply to sequential LEDs.

Show Command

CTL	END
'S'	'\n'

Applies updates to the LEDs... without calling this, the other commands have not affect on your LEDs.

Clear Command

CTL	END
'C'	'\n'

Clears all pixels. Send a Show command to update the LEDs.

Example

The following example sets up a strip of 6 LEDs and sets them to red

I06
R00ff0000ff0000ff0000ff0000ff0000ff0000
S

The following applies HSV to show colors across the color spectrum

I06
H0000ffff20ffff40ffff60ffff80ffffa0ffff
S
