--------------------------------------------
void delay_ms(unsigned int i)
{
  unsigned char j;
  unsigned char p;
  for(j=0;j<i;j++)
  for(p=0;p<933;p++)
} //example: delay_ms(50);
--------------------------------------------
void delay(void)
{
unsigned int k  = 0;
unsigned int j  = 0;
unsigned int g  = 0;
for(j=0;j<12000;j++)
{
         k = 5;
         //k ^=5;
}
