Enable LED strip driver for daisy chains of LPD880x
|
||
|
|
(LPD8803, LPD8806, or compatible) devices.
|
||
|
|
|
||
|
|
Each LPD880x LED driver chip has some output channels
|
||
|
|
(3 channels for LPD8803, 6 for LPD8806), whose PWM
|
||
|
|
duty cycle can be set at 7 bit resolution via a
|
||
|
|
reduced SPI interface (MOSI and CLK lines only).
|
||
|
|
Each chip also includes data and clock out pins for
|
||
|
|
daisy chaining LED strips.

SPI clock rate, in Hz, to use while driving the strip.

The recommended maximum is 2 MHz (2000000); the absolute maximum

is 20 MHz (20000000). If unsure, accept the default value.
