sent.

NOTE: In LCD_driver.c must comment out #include “main.h”

Now that we have our specification we can run off willy-nilly and write the
software.

We write the Demonstrator.h file:

// Demonstrator.h LCD demo version
void initializer(void);
void parseInput(char *);

include "Demonstrator.h"

DEMO[] PROGMEM = "'LCD' demo.\r\r\0";

And the Demonstrator.c file:

// Demonstrator.c LCD demo version

#include "PC_Comm.h"

#include "LCD_test.h"
#include "LCD_driver.h"
#include "LCD_functions.h"

// identify yourself specifically
const char TALKINGTO[] PROGMEM = "\r\rYou are talking to the \0";
const char WHO

// bad command
const char BAD_COMMAND1[] PROGMEM = "\rYou sent: '\0";
const char BAD_COMMAND2[] PROGMEM = "' - I don't understand.\r\0";

const char LCD_START_msg[] PROGMEM = "LCD demo\0";

void initializer()
{
// Calibrate the oscillator:
OSCCAL_calibration();

// Initialize the USART
USARTinit();

// initialize the LCD
LCD_Init();

// Display instructions on PC
