How to send conversion axis command to acclerometer thru SPI interface to PIC18f452

[anilvadnala]

Dear Frens,

I Anil Vadnala doing work on PIC18f452 first time as all say

I need to interface digital tri axis accelerometer to PIC18f452 through SPI
interface.

I wrote a C program what I understand from data sheet of accelerometer given in 13th page onwards.

#include<18f452.h>
#use delay (clock=6000000)
#use rs232 ( baud= 9600, xmit=PIN_C6, rcv= PIN_C7 )
#include<input.c>
#include<spi.c>
//#include<ACCL.h>
VOID main()
{
unsigned int a,b,FF_int=0x06, FF_delay=0x07, MOT_int=0x08, MOT_delay=0x09
                 XOUT_H, XOUT_L, YOUT_H, YOUT_L, ZOUT_H, ZOUT_L;
unsigned char spi_write, spi_read;
                          //spi_write(0x06 && 0x14)
spi_write(FF_int);
spi_write(0x14);
delay_us(130000);
                           //spi_write(0x07 && 0x14)
spi_write(FF_delay);
spi_write(0x14);
delay_us(130000);
                           //spi_write(0x08 && 0x4d)
spi_write(MOT_int);
spi_write(0x4d);
delay_us(130000);
                           //spi_write(0x09 && 0x14)
spi_write(MOT_delay);
spi_write(0x14);
delay_us(130000);
                           //void spi_io(void);
{
setup_spi(spi_master, spi_slave)

CS=0                           //chip slect low to write to registers

                              //  conversion command
spi_write(0x80);

Pleas frens this is my first C program for PIC using SPI so give suggesions where I went wrong.

Thanks in advance
