LEDs driver for National Semiconductor LP3944 Funlight Chip http://www.national.com/pf/LP/LP3944.html This helper chip can drive up to 8 leds, with two programmable DIM modes; it could even be used as a gpio expander but this driver assumes it is used as a led controller. The DIM modes are used to set _blink_ patterns for leds, the pattern is specified supplying two parameters: - period: from 0s to 1.6s - duty cycle: percentage of the period the led is on, from 0 to 100 LP3944 can be found on Motorola A910 smartphone, where it drives the rgb leds, the camera flash light and the displays backlights.

value 0 means off, 1..127 means blink at 0.5Hz and 128..255 means
|
