Newbie question on reading port staus

I am sure this is real simple:

OK, so I have inputs on PortB.0 through PortB.7.

How can I read the status of this as a whole?

For example if PortB.0, PortB.1 and PortB.3 are all HIGH then I want to retun the digit "11"....and so forth from 0-127.

Thanks!

Hi,
Just read the Port register:

Code:

---

myValue = PortB

---

That's it.

EDIT: Make sure to check and setup stuff like ADCON, CMCON for any pins you're going to use.

Ah, if only all things in life were this easy!
Thanks!!!

Now, how do I get the value of the Port if the port is less than 8 bits?

Thanks!

Exactly the same way as before.
On a 16F877, for example, PortA is 6bits. Reading it will return a byte with the state of the port pins in the lower 6 bits, the two high bits will always read zero.
PortE on the 16F877 is only 3bits. Reading it will return a byte with the state of the port pins in the lower 3 bits, the upper 5 bits will always read zero.

If you look at the register summary in the datasheet for the 16F877 (or whatever device you're actually using) it's all pretty clear.

Yes, that makes good sense. But what if I only use say 4 bits of the PortA port in my code and make the other PortA bits as outputs? Would reading the port give me the correct result?
:-)

it will also return the state of the output. Nothing hard to solve through a bitwise operation or simply by breading the bits you need.

Awesome!! THX!!
