From the data sheet:
|
|
|
|
(TH+TL=1.25μs±600ns)
|
|
|
|
T0H, 0 code, high level time, 350ns ±150ns
|
|
T0L, 0 code, low level time, 1360ns ±150ns
|
|
T1H, 1 code, high level time, 1360ns ±150ns
|
|
T1L, 1 code, low level time, 350ns ±150ns
|
|
WT, Wait for the processing time, NA
|
|
Trst, Reset code,low level time, 24µs
|
|
|
|
To normalise the pulse times so they fit in 4 SPI bits:
|
|
|
|
On the assumption that the "low" time doesnt matter much
|
|
|
|
A SPI bit time of 0.40uS = 2.5 Mbit/sec
|
|
T0 is sent as 1000
|
|
T1 is sent as 1110
|
|
|
|
With a bit of excel testing, we can work out the maximum and minimum speeds:
|
|
2000000 MIN
|
|
2235000 AVG
|
|
2470000 MAX
|
|
|
|
Wait time:
|
|
Not Applicable for WS2812
|
|
|
|
Reset time:
|
|
using the max of 2470000, the bit time is 405nS
|
|
Reset time is 24uS = 59 bits = 8 bytes
