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 | 20:a266fa588bd8 | 9 | * An operation sample of PCU9669 I2C bus controller. |
| nxp_ip | 20:a266fa588bd8 | 10 | * The mbed accesses the PCU9669's parallel port (8 bit address and 8 bit data) using bit-banging. |
| nxp_ip | 20:a266fa588bd8 | 11 | * The bit-banging is poerformed by PortInOut function of mbed library. |
| nxp_ip | 20:a266fa588bd8 | 12 | * |
| nxp_ip | 20:a266fa588bd8 | 13 | * To make the code porting easier, all codes are partitioned into layers to abstract other parts. |
| nxp_ip | 20:a266fa588bd8 | 14 | * The mbed specific parts are concentrated in lowest layer: "hardware_abs.*". |
| nxp_ip | 20:a266fa588bd8 | 15 | * This module may need to be modified when porting. |
| nxp_ip | 20:a266fa588bd8 | 16 | * |
| nxp_ip | 20:a266fa588bd8 | 17 | * All other upper layers are writen in standard-C. |
| nxp_ip | 20:a266fa588bd8 | 18 | * |
| nxp_ip | 20:a266fa588bd8 | 19 | * base code is written from 05-Sep-2011 to 09-Sep-2011. |
| nxp_ip | 20:a266fa588bd8 | 20 | * And demo code has been build on 11-Sep-2011. |
| nxp_ip | 20:a266fa588bd8 | 21 | * Debug and code adjustment has been done on 08-Sep-2011. |
| nxp_ip | 20:a266fa588bd8 | 22 | * Small sanitization for main.cpp. All mbed related codes are moved in to "hardware_abs.*". 13-Oct-2011 |
