my code is like that

int8 value1,value2,value3;
value1=0x11110000;
value2=0x00001010;

hi,
in your expression,
| Code: | | value3=(value1 && value2); |
do not use double &.
use like this
| Code: | | value3=(value1 & value2); |

Use a single "&" and don't use "&&"
"&&" does an AND comparison. The single "&" is for the mathematical operation.

You have declared value1, value2 & value3 as 8-bit variables yet you are assigning a 4-BYTE value to them. 0x11110000 indicates a HEX value. If you want to assign an 8-bit value then use 0b11110000. This will greatly affect your program.
