5 * The driver supports controllers with a very simple SPI protocol:
6 * - one LED is controlled by a single byte on MOSI
7 * - the value of the byte gives the brightness between two values (lowest to
8 * highest)

--- 16 unchanged lines hidden (view full) ---

25 * slight jump in the pattern at 0x10.
26 * * Mode: 11 -> blinking (off -> 25% -> off -> 25% -> ...) with a period of
27 * (105ms * parameter)
28 * NOTE: This driver currently only supports mode 00.
