I am trying to interface AD7321 with Microcontroller 8051. This is the code i came up with referring to the datasheet. Please tell me what is wrong with it.
#include<reg51.h>
sbit CS=P0^0;
sbit SCLK=P0^1;
sbit DIN=P0^2;
sbit DOUT=P0^3
sbit MSB=ACC^7;
sbit LSB=ACC^0;
void main(void)
{
unsigned char ranreg=
unsigned char ctrlreg=
unsigned char x;
while(1)
{
ACC=rangereg;
CS=0;
for(x=0;x<17;x++)
{
sclk=1;
DIN=MSB;
DELAY();
SCLK=0;
DELAY();
ACC=ACC<<1;
}
ACC=ctrlreg;
for(x=0;x<17;x++)
{
sclk=1;
DIN=MSB;
DELAY();
SCLK=0;
DELAY();
ACC=ACC<<1;
}
for(x=0;x<17;x++)
{
SCLK=1;
DELAY();
SCLK=0;
DELAY();
}
for(x=0;x<17;x++)
{
SCLK=0;
DELAY();
SCLK=1;
DELAY();
LSB=DOUT;
ACC=ACC<<1;
}
CS=1;
}
