◆ WS281X_T_DATA_NS
| #define WS281X_T_DATA_NS (1250U) |
Data transmission time in nanoseconds.
For the SK6812, WS2812 and WS2812b this is 1.25 µs. This is the total time required to transmit one bit.
Definition at line 37 of file ws281x_constants.h.
◆ WS281X_T_END_US
| #define WS281X_T_END_US (80U) |
Time in microseconds to pull the data line low to signal end of data.
For the WS2812 it is ≥ 50µs, for the SK6812 it is ≥ 80µs. We choose 80µs to be compatible with both.
