Detailed Description
Implementation of the LedDevice interface for writing to LDP6803 led device.
00000000 00000000 00000000 00000000 1RRRRRGG GGGBBBBB 1RRRRRGG GGGBBBBB ... |------------------------------—| |------------—| |------------—| 32 zeros to start the frame Led1 Led2 ...
For each led, the first bit is always 1, and then you have 5 bits each for red, green and blue (R, G and B in the above illustration) making 16 bits per led. Total bytes = 4 + (2 x number of leds)
