Fork of mini_board_PCU9669 by InetrfaceProducts NXP

What is this?

This is a sample code to operate PCU9955 (16ch constant-current LED controller) and PCA9629 (intelligent stepper motor controller) through PCU9669 (3 channels (UltraFast mode * 2ch, FastModePlus *1ch) I2C bus controller).

This demo is written based on mini_board_PCU9669 sample code library and its API.
http://mbed.org/users/nxp_ip/code/mini_board_PCU9669/

Demo will shows how the LED controllers and stepper motor controllers works.
It uses a mini_board_PCU9669 board with mbed, 8 of PCU9955s and 5 PCA9629s.
