Good day,
to test my C source code file I added the following lines:
printf(“ r1 = %d\n", r1);
→ Display in the terminal program: “r1 = 514”
printf("key = %x = %c = %d\n", key, key, key);
→ Display in the terminal program: “key = 101 = □ = 0”
printf("r1 = %x = %c = %d\n", r1, r1,r1);
→ Display in the terminal program: “r1 = 202 = □ = 0”
I declared the variables as follows:
unsigned char data r1 = 0; → 0-255
bit data key = 0; → 0 or 1
Unfortunately I can't explain why the values out of the range (0-255, 0-1) are displayed?
Compiler: Keil-C version V5.38.0.0
Kind Regards
Juergen
