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.
