NeoPixel
Implements the NeoPixel protocol for driving addressable LED strips. The strip length is configured in the unit settings.
Five color data encodings are available for user convenience.
Commands
CLEAR (0x00)
Set all pixels to black. This is also automatically executed on start-up to clear the strip.
LOAD (0x01)
Load packed RGB data to the strip.
Payload:
- a byte array
(R,G,B)x length
LOAD_U32_ZRGB (0x08)
Load 32-bit 0x00RRGGBB words encoded in big-endian as (0,R,G,B).
Payload:
- a byte array
(0,R,G,B)x length
LOAD_U32_ZBGR (0x09)
Load 32-bit 0x00BBGGRR words encoded in big-endian as (0,B,G,R).
Payload:
- a byte array
(0,B,G,R)x length
LOAD_U32_RGBZ (0x0A)
Load 32-bit 0x00BBGGRR words encoded in little-endian as (R,G,B,0).
Payload:
- a byte array
(R,G,B,0)x length
LOAD_U32_BGRZ (0x09)
Load 32-bit 0x00RRGGBB words encoded in little-endian as (B,G,R,0).
Payload:
- a byte array
(B,G,R,0)x length
GET_LEN (0x04)
Read the neopixel strip length as configured in the settings.
Response:
- u16 - number of pixels
