Bits to Word?

[BigWumpus]

In the past I used .lowbyte and .highbyte instead of .byte0 and .byte1.
What does the compiler do ?

It actually compiled without any problems. But now I think I have another question. If I had a byte that represents different config bits, how can I set each bit individually?

If I had variable set as testbit VAR databyte1.0, will bit0 of databyte1 change if I set testbit to another value?

Errr.... how would I also set multiple bits in a byte? Say, I want to set bit5 to bit0 to a certain value.

Thanks!

Sorry to be impolite and a pest but why don't simply test it and send results to a LCD or via Serial communication to your PC to see what's happen with?

Hi mister_e,

:-) Sorry, I was feeling a bit lazy. Plus, I don't have the most efficient computer setup in the world. Anyway, this actually the question that I can't figure out: how would I set multiple bits in a byte simultaneously? Say, I want to set bit5 to bit0 to a certain value.

I was hoping there was something like this:

databyte1.[5 to 0] = %101011

Hi:
You can create aliases for each configuration bit. Ex:
name1 var byte1.0
name2 var byte1.2 etc.
then, you can clear or set each one by

name1 = 0, or name1 = 1

Or you can test them:
if name1 = 1 then do_something
I hope this helps.

To set bit 4 on and leave the rest unchanged:

mybyte=mybyte | %00010000 'OR function with selected bit masked ON

To turn bit 4 off and leave the rest unchanged:

mybyte=mybyte & %11101111 'AND function with selected bit masked OFF

OR you can set multiple bits on or off by either ADDING or SUBTRACTING the bit weight to/from either 0 or 255 respectively.
