/** A sample code for "mini board PCU9669/PCA9665" * * @author Akifumi (Tedd) OKANO, NXP Semiconductors * @version 1.0 * @date 26-Mar-2011 * * Released under the MIT License: http://mbed.org/license/mit * * An operation sample of PCU9669/PCA9665 I2C bus controller. * The mbed accesses the bus controller's parallel port (8/2 bit address and 8 bit data) by 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 for the 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 * hardware_abs are moved into parallel_bus library folder, 3 LED driver operation sample 13-Feb.-2012 * PCU9669 and PCA9665 codes are packed in a project 14-Feb-2012. * * Before builidng the code, please edit the file mini_board_PCU9669/config.h * Un-comment the target name what you want to target. */ #include "config.h" #include "hardware_abs.h" #include "PCA9665_access.h" #include "PCx9955_reg.h" #include "PCA9629_reg.h" #include "utility.h" #include "mbed.h" // this header is required only when printf() is used. #ifdef CODE_FOR_PCA9665 #define RESET_PULSE_WIDTH_US 100 #define RESET_RECOVERY_US 100 char PCx9955_reg_data[] = { 0x80, // Strat register address with AutoIncrement bit 0x00, 0x05, // MODE1, MODE2 0xAA, 0xAA, 0xAA, 0xAA, // LEDOUT[3:0] 0x80, 0x00, // GRPPWM, GRPFREQ PWM_INIT, PWM_INIT, PWM_INIT, PWM_INIT, // PWM[3:0] PWM_INIT, PWM_INIT, PWM_INIT, PWM_INIT, // PWM[7:4] PWM_INIT, PWM_INIT, PWM_INIT, PWM_INIT, // PWM[11:8] PWM_INIT, PWM_INIT, PWM_INIT, PWM_INIT, // PWM[15:12] IREF_INIT, IREF_INIT, IREF_INIT, IREF_INIT, // IREF[3:0] IREF_INIT, IREF_INIT, IREF_INIT, IREF_INIT, // IREF[7:4] IREF_INIT, IREF_INIT, IREF_INIT, IREF_INIT, // IREF[11:8] IREF_INIT, IREF_INIT, IREF_INIT, IREF_INIT, // IREF[15:12] 0x08 // OFFSET: 1uS offsets }; char PCx9955_reg_read_start_address = 0x80; char read_buffer[ 41 ]; int main() { int count = 0; int i; int j; printf( "\r\nPCU9665 simple demo program on mbed\r\n build : %s (UTC), %s \r\n\r\n", __TIME__, __DATE__ ); hardware_initialize(); // initializing bit-banging parallel port reset( RESET_PULSE_WIDTH_US, RESET_RECOVERY_US ); PCA9665_init(); // set_speed_mode( SPEED_STD_MODE ); // set_speed_mode( SPEED_FAST_MODE ); set_speed_mode( SPEED_FAST_MODE_PLUS ); // set_buffer_mode( DISABLE ); set_buffer_mode( ENABLE ); while ( 1 ) { for ( i = 0; i < 16; i++ ) { for ( j = 0; j < 256; j += 4 ) { PCx9955_reg_data[ 9 + i ] = j; if ( i & 0x01 ) set_buffer_mode( ENABLE ); else set_buffer_mode( DISABLE ); i2c_write( PCx9955_ADDR0, PCx9955_reg_data, sizeof( PCx9955_reg_data ), NEXT_RESTART ); i2c_write( PCx9955_ADDR0, &PCx9955_reg_read_start_address, sizeof( PCx9955_reg_read_start_address ), NEXT_RESTART ); i2c_read( PCx9955_ADDR0, read_buffer, sizeof( read_buffer ), STOP ); // dump_read_data( read_buffer, sizeof( read_buffer ) ); wait( 0.01 ); count++; } } for ( i = 0; i < 16; i++ ) PCx9955_reg_data[ 9 + i ] = 0; } } #endif // CODE_FOR_PCA9665
