You will need to look at the data sheet for the ads7844 to figure out how to communicate it.
If you do not have a driver for the LCD you need to look at its data sheet to figure out how to use it.

unsigned int yourReadAdcFunc(void)
{
  unsigned int result;
   // code as needed
   ...
  return result;
}

void yourLcdDisplayFunc(unsigned int  val)
{
  // convert val to a string and display it on the LCD
  ...
}

void main(void)
{
  // init LCD
  ...
  // init ADC
  ...
  while(1)
  {
      unsigned int adcVal;
      adcVal = yourReadAdcFun();
      yourLcdDisplayFunc(adcVal);
 }
}
