Summary
In summary, each update of an APA102 based LED string should consist of the following:
1\. A start frame of 32 zero bits (<0x00> <0x00> <0x00> <0x00>)
2\. A 32 bit LED frame for each LED in the string (<0xE0+brightness>
3. An end frame consisting of at least (n/2) bits of 1, where n is the number of LEDs in the string.*
