How to get determine the value of an output port (SOLVED)

[ambokyo]

Assuming PORT B is outputting 0xFF. How can I read the status of PORT B so I could determine the output state?

Sorry for being such a noob in CCSC but CCSC doesn't seem to recognize PORTB keyword.

Multiple parts:

If you have just output '0', then you already know what has been output.....

If you are using 'fast_io' mode, then input_b() returns the state of the port.

Input_state returns the state of a pin, without changing the port direction.

Normally the input instruction _will_ set the port as an input automatically.

You can define PORTB as a variable mapped to the output latch, using #byte.

If you have the IDE, then 'tools', 'device editor', 'registers', 'make include file', will automatically build a file with all the registers and bits defined for you.

Thanks so much.

#byte and #bit is exactly what I was looking for.
