Condition testing

[jtburnham]

I'm using PBPro and I hoping someone can answer a fairly simple question for me. I want to test for 1 or more set bits on port a.

For single bit testing, this doesn't work -

IF (porta AND %00000001) THEN ...

This also doesn't work -

IF (porta AND %00000001) = 1 THEN ...

For multiple bit testing, this doesn't work -

IF (porta AND %00000101) THEN ...

This also doesn't work -

IF (porta AND %00000101) = 1 THEN ...

Is there another way besides IF (porta.0 = 1 AND porta.3 = 1) THEN... to test for set bits? I thought AND was an accepted test for byte testing.

Thank you for your help.

IF (porta AND %00000101) = 1 THEN

Your logic is flawed because for example if bit PortA.2 is set then the equation would equal 4 and not 1.

Try this instead...

If (PortA and %00000101)<>0 then

Inside the parenthesis the test is logical but outside is a comparison of two numbers. It is allways 'false' condition...

Your logic is flawed ...

My wife frequently makes the same observation.

I do see where I was going wrong.

Thank you all.

See? As always women are addressing (here Melanie...) this kind of problems!
