strips

Array of configurations for the individual LED strips:

Setting	Description	Type	Default	Example	Max
pin	The GPIO pin used to send data to the LED strip.	integer	N/A	18	N/A
num	The number of pixels in the LED strip.	integer	60	120	1000
colorOrder	Color order for the strip hardware. Used to derive bytes-per-pixel.	string	GRB	RGB, GRB, BGR, RGBWW, GRBWW	N/A
rmtHz	The RMT (Remote Control) resolution in Hz for communication with the LEDs.	integer	10000000	12000000	N/A
T0H, T0L, T1H, T1L	WS2812 timing parameters in microseconds. T0H = high time for 0 bit, T0L = low time for 0 bit, T1H = high time for 1 bit, T1L = low time for 1 bit. (Legacy names: bit0_0Us, bit0_1Us, bit1_0Us, bit1_1Us also supported)	float	0.4, 0.85, 0.8, 0.45	N/A	N/A
resetUs	The reset time in microseconds between data frames for the LEDs.	float	100.0	N/A	N/A
msbFirst	Whether the most significant bit (MSB) is transmitted first.	boolean	true	N/A	N/A
stopAfterTx	Whether to stop the RMT peripheral after transmission is complete.	boolean	false	N/A	N/A
blockingShow	Whether the show function should block until the LED update is complete.	boolean	false	N/A	N/A
powerPin	The GPIO pin used to control power to the LED strip.	integer	N/A	5	N/A
pwrOnLvl	The level at which the power pin is activated (high or low).	integer	1	N/A	N/A
offAfterMs	The amount of time (in milliseconds) to wait before turning off the power if all pixels are off.	integer	0	N/A	N/A
bpp	Bytes per pixel override. If colorOrder is set, this is ignored with a warning.	integer	Derived	3, 5	N/A

segments

An array of LED segments to which patterns and other control can be applied:

Setting	Description	Type	Default	Example
name	The name of the LED segment.	string	N/A	"Segment1"
start	The start offset of the segment from the beginning of the LED strip.	integer	N/A	0
num	The number of pixels in the segment.	integer	N/A	60
pattern	The initial pattern to apply to the segment.	string	N/A	"rainbow"
patternMs	The duration (in milliseconds) for the initial pattern.	integer	N/A	1000
brightnessPC	The brightness level for the segment, as a percentage.	float	100.0	75.0
startupFirstPixel	The color of the first pixel on startup, in hexadecimal format.	string	N/A	"FF0000"
colorOrder	Optional logical color order for the segment. If the strip colorOrder is set, it is used for on-wire encoding.	string	"GRB"	"GRB"

Notes:

• colorOrder is a strip-level hardware setting; it determines bytes-per-pixel and on-wire ordering.
• Segment colorOrder is optional and should be treated as a logical transform only.
