demo sample to drive PCU9955 and PCA9629

Dependencies:   mbed I2C_slaves PCU9669 parallel_bus

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.

nxp_ip 0:de9a15767563 8 *
nxp_ip 0:de9a15767563 9 * An operation sample of PCU9669/PCA9665 I2C bus controller.
nxp_ip 0:de9a15767563 10 * The mbed accesses the bus controller's parallel port (8/2 bit address and 8 bit data) by bit-banging.
nxp_ip 0:de9a15767563 11 * The bit-banging is poerformed by PortInOut function of mbed library.
nxp_ip 0:de9a15767563 12 *
nxp_ip 0:de9a15767563 13 * To make the code porting easier, all codes are partitioned into layers to abstract other parts.
nxp_ip 0:de9a15767563 14 * The mbed specific parts are concentrated in lowest layer: "hardware_abs.*".
nxp_ip 0:de9a15767563 15 * This module may need to be modified for the porting.
nxp_ip 0:de9a15767563 16 *
nxp_ip 0:de9a15767563 17 * All other upper layers are writen in standard-C.
nxp_ip 0:de9a15767563 18 *
nxp_ip 0:de9a15767563 19 * base code is written from 05-Sep-2011 to 09-Sep-2011.
nxp_ip 0:de9a15767563 20 * And demo code has been build on 11-Sep-2011.
nxp_ip 0:de9a15767563 21 * Debug and code adjustment has been done on 08-Sep-2011.
nxp_ip 0:de9a15767563 22 * Small sanitization for main.cpp. All mbed related codes are moved in to "hardware_abs.*". 13-Oct-2011
nxp_ip 0:de9a15767563 23 * hardware_abs are moved into parallel_bus library folder, 3 LED driver operation sample 13-Feb.-2012
nxp_ip 0:de9a15767563 24 * PCU9669 and PCA9665 codes are packed in a project 14-Feb-2012.
nxp_ip 0:de9a15767563 25 *
nxp_ip 0:de9a15767563 26 * Before builidng the code, please edit the file mini_board_PCU9669/config.h
nxp_ip 0:de9a15767563 27 * Uncomment the target name what you want to target.
