Unsigned char
example 7-1
#include <reg51.h> void main (void) { unsigned char z; for (z=0;z<=255;z++) P1=z; }
example 7-2
#include <reg51.h> void main (void) { unsigned char mynum [] = "012345ABCD"; unsigned char z; for (z=0;z<=10;z++) P1 = mynum[z]; }
example 7-3
#include <reg51.h> void main (void) { for (;;) //opakovani cyklu P1=0x55; P1=0xAA; }
Unsigned char
example 7-4
- include <reg51.h>
void main (void)
{
char mynum [] = {+1,-1,+2,-2,+3,-3,+4,-4}; unsigned char z;
for (z=0;z<=8;z++) P1 = mynum[z];
}
