Embedded programming

This is the best technology now.

 

Right, now you can see the code:

Code:

//time waste function, to wait time given sleeptime[ms]
void sleep(int sleeptime)
{
    int i,j;
    for (i = 0;i < sleeptime; i++)
   {    
       for (j = 0;j < 20000; j++)
   }
}

int main( void) {
  int a,row;
  unsigned char k;
  PB.DDR = 0xff;
  P4.DDR = 0xff;
  while (1){
    a = 0x80;
    for (row = 0;row < 8;row ++){
       P4.DR.BYTE = a;
       PB.DR.BYTE = ~(ascii['A'][row]);
      sleep(1);
      a >>=1;
    }
   return 0;
}

There's the code to design for the KID (8*8)
Seem very easy, but it's more difficult. because you should understand about Interupt.

 

oh, you can research assembly for your skill in embedded programming. Especially interupters. It's very large and difficult.
