Source Code:
//
#include avr/io.h 
#include avr/pgmspace.h 
#define lcm_DI_SET   PORTD=_BV(PD7) 

void lcm_WriteByte(unsigned char dat) 
{ 
   lcm_DI_SET; 
} 
void lcm_Show(unsigned char column, prog_void *addr) 
{ 
   unsigned char i, m; 
   for(m = 0; m  8; m++) 
   { 
  i = pgm_read_byte(addr + m); 
  lcm_WriteByte(i); 
   } 
} 
int main(void) 
{ 
   while(1); 
}
