Jasper Wallace / LPD8806

Library for LPD8806 (and probably LPD8803/LPD8809) PWM LED driver chips, strips and pixels. Standard connected to 1st hardware SPI module. Data -> p5 and Clock -> p7 use a fixed sized buffer rather than malloc - if we use malloc rtos is unhappy...

Fork of LPD8806 by Jelmer Tiete
