How to update only a single bit from a byte.

Anubisbot

Hi, how di i update only a single bit from a byte.

I have a byte caled state0 and it beginning value is %0000_0001

then i want to update it to %00010_0001

then to %0101_0001 to change a bit without changing the other bits.

is there a way to say bit 5 from stat0 = 0


Thanx Anubisbot

Use the logical bit operators (& | ^) and their assignment versions (&= |= ^=).

Like: state0 |= %0010_0000

Then: state0 ^= %0111_0000 or some equivalent

Aha, like i thought, after looking once again to the operators in the manual.
Thank you Mike...
