Help! PIC16F877A and SM Bus

[deniska_gus]

Hello!

Can anyone help me to find an answer, why my code is wrong. I'm reading out an IC BQ2085 and i cann't see anything, if i use Hyper Terminal.
[code]
#include <16F877A.h>
#fuses XT,NOWDT,NOPROTECT,PUT,BROWNOUT,NOLVP,NOWRT
#use delay(clock=4000000)
#use rs232(baud=9600, xmit=PIN_c6, rcv=PIN_c7,parity=n,bits=8,ERRORS)
#use i2c(Master, sda=PIN_C4, scl=PIN_C3, SMBUS)

int8 datal, datah;
int16 data;

void read()
{
i2c_start(); // Start
i2c_write(0x16); //Battery Adress + R/W=0
i2c_write(0x17);// Command Word ( CycleCount)
i2c_start(); // Start
i2c_write(0x17);// Battery Address + R/W=1
datal=i2c_read();
i2c_write(0);
datah=i2c_read();
i2c_write(1);
i2c_stop(); //Stop
data=make16(datah, datal);
}

void send()
{

printf("%2ld\r\n", data);

}


void main()
{
while(1)
{
read();
send();
delay_ms(500);
}
}

I cann't post the datasheet, sorry.

What is this ?

But in the datasheet i can see just NAK after the last read !?

This is how you do it in CCS:

PCM programmer, you are the King. Thank you very much.
