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.

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.

/*  A sample code for PCU9669 (and its family) operation sample
 *  @author  Tedd OKANO, NXP Semiconductors
 *  @version 0.5
 *  @date    13-Oct-2011
 *  Released under the MIT License:
 *    An operation sample of PCU9669 I2C bus controller. 
 *  The mbed accesses the PCU9669's parallel port (8 bit address and 8 bit data) using bit-banging. 
 *  The bit-banging is poerformed by PortInOut function of mbed library. 
 *    To make the code porting easier, all codes are partitioned into layers to abstract other parts. 
 *    The mbed specific parts are concentrated in lowest layer: "hardware_abs.*". 
 *    This module may need to be modified when porting. 
 *    All other upper layers are writen in standard-C. 
 *    base code is written from 05-Sep-2011 to 09-Sep-2011.
 *    And demo code has been build on 11-Sep-2011. 
 *    Debug and code adjustment has been done on 08-Sep-2011. 
 *    Small sanitization for main.cpp. All mbed related codes are moved in to "hardware_abs.*". 13-Oct-2011
