MMA7660 example program

I need an example program that initializates the accelerometer and read the x, y, z coordenades which are putting in variables and then I will use them on a lcd screen.

Thanks, I need it for a fhysics project

The following is processor expert:

main.c

 error = I2C1_SelectSlave(0x4C);

 buf[0] = 0x07;
 buf[1] = 0x00;
 error = I2C1_SendBlock(buf, 2, &sent);
 while(!TransmitComplete){}
 TransmitComplete = 0;
 error = I2C1_SendStop();

 buf[0] = 0x05;
 buf[1] = 0x00;
 error = I2C1_SendBlock(buf, 2, &sent);
 while(!TransmitComplete){}
 TransmitComplete = 0;
 error = I2C1_SendStop();

 buf[0] = 0x06;
 buf[1] = 0x10;
 error = I2C1_SendBlock(buf, 2, &sent);
 while(!TransmitComplete){}
 TransmitComplete = 0;
 error = I2C1_SendStop();

 buf[0] = 0x09;
 buf[1] = 0xE0;
 error = I2C1_SendBlock(buf, 2, &sent);
 while(!TransmitComplete){}
 TransmitComplete = 0;
 error = I2C1_SendStop();

 buf[0] = 0x08;
 buf[1] = 0x62;
 error = I2C1_SendBlock(buf, 2, &sent);
 while(!TransmitComplete){}
 TransmitComplete = 0;
 error = I2C1_SendStop();

 buf[0] = 0x0A;
 buf[1] = 0x00;
 error = I2C1_SendBlock(buf, 2, &sent);
 while(!TransmitComplete){}
 TransmitComplete = 0;
 error = I2C1_SendStop();

 buf[0] = 0x07;
 buf[1] = 0x41;
 error = I2C1_SendBlock(buf, 2, &sent);
 while(!TransmitComplete){}
 TransmitComplete = 0;
 error = I2C1_SendStop();

 buf[1] = 0;

 for(;;)
 {
  while(Bit1_GetVal());
  TransmitComplete = 0;
  buf[0] = 0;
  error = I2C1_SendBlock(buf, 1, &sent);
  while(!TransmitComplete){}
  error = I2C1_RecvBlock(&data,3,&ret);
  error = I2C1_SendStop();
 }

event.c

void I2C1_OnTransmitData(void)
{
  /* Write your code here ... */
 TransmitComplete = 1;
}
