// 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).
//
// Assuming we only want to send these edges in groups of size K, the
// C/C++ expression for the minimum number of groups to send is:
//
// ((count - 1) + (K - 1)) / K
//
// The C/C++ expression above is just (count - 1) divided by K,
// rounded up to the nearest whole number if there is a remainder.
//
// We set K to 16 and use the formula above as the number of frame-end
// bytes to transfer. Each byte has 16 clock edges.
//
// We are ignoring the specification for the end frame in the APA102
// datasheet, which says to send 0xFF four times, because it does not work
// when you have 66 LEDs or more, and also it results in unwanted white
// pixels if you try to update fewer LEDs than are on your LED strip.
