Pic+isd4002

[angie14]

currently I made the next circuit

i found in this page http://hem.passagen.se/communication/speach.html
and I find the next firm for the pic

#include <REGX52.H>

#include <string.h>

#include <stdio.h>

#include <absacc.h>

#include <intrins.h>

sbit ss=P1^0;

sbit mosi=P1^1;

sbit sclk=P1^4;

void delay_ms(unsigned int ms)

{

unsigned char i;

while(ms--)

{

i=112;

while(i--);

}

}

void spi_mosi(unsigned char spi_data)

{

unsigned char BitCnt;

mosi=0;

sclk=0;

for(BitCnt=0;BitCnt<8;BitCnt++)

{

sclk=0;

_nop_();

if((spi_data>>BitCnt)&0x01)

mosi=1;

else

mosi=0;

_nop_();

_nop_();

_nop_();

sclk=1;

_nop_();

_nop_();

_nop_();

}

_nop_();

_nop_();

_nop_();

}

void play_isd4002(unsigned int addr)

{

unsigned char addr_l,addr_h;

addr_l=addr;

addr_h=addr>>8;

addr_h=addr_h|0xe0;

ss=0;

spi_mosi(0x20);

ss=1;

delay_ms(50);

ss=0;

spi_mosi(addr_l);

spi_mosi(addr_h);

ss=1;

delay_ms(10);

ss=0;

spi_mosi(0xf0);

ss=1;

}

void stop_isd4002()

{

ss=0;

spi_mosi(0x70);

ss=1;

delay_ms(50);

}

void main()

{

play_isd4002(0x86);

}

but i can't record the file... so I need a correct configuration for the ISD4002 ...thanks
