- // We need to send some more bytes to ensure that all the LEDs in the
- // chain see their new color and start displaying it.
- //
- // The data stream seen by the last LED in the chain will be delayed by
- // (count - 1) clock edges, because each LED before it inverts the clock
- // line and delays the data by one clock edge. Therefore, to make sure
- // the last LED actually receives the data we wrote, the number of extra
- // edges we send at the end of the frame must be at least (count - 1).
- // For the APA102C, that is sufficient.
- //
- // The SK9822 only updates after it sees 32 zero bits followed by one more
- // rising edge. To avoid having the update time depend on the color of
- // the last LED, we send a dummy 0xFF byte. (Unfortunately, this means
- // that partial updates of the beginning of an LED strip are not possible;
- // the LED after the last one you are trying to update will be black.)
- // After that, to ensure that the last LED in the chain sees 32 zero bits
- // and a rising edge, we need to send at least 65 + (count - 1) edges. It
- // is sufficent and simpler to just send (5 + count/16) bytes of zeros.
- //
- // We are ignoring the specification for the end frame in the APA102/SK9822
- // datasheets because it does not actually ensure that all the LEDs will
- // start displaying their new colors right away.
