Trying to float multible pins and lower one effiecently

[iso9001]

This is kind of a continuation of my other thread, but I've changed the ules a bit.

I'm constantly picky one pin determined from an input somewhere else in my code. And when I see a pin has to be selected, I make it output_low and float the rest, easy enough. I'm using C7, C6, C5, C4, B1, and B2. When I'm setting or floating however I can not change any other pins (ie: B0, C2, etc) I have some code that looks good to me, but isnt working.

Not sure what you're trying to do, but if you want to switch a pin
between a Logic-low state and floating, then set all the pins that
you're using to a low level. Then to switch between Low and Floating,
just change the TRIS for those bits to be either an output or an input.

This is how CCS does it in their software i2c library code.
They set the port latch bits for SDA and SCL low, and then they
switch those pins between having a low-level out and floating
by just flipping the TRIS bits. Of course, those pins have pull-ups
on them, so when they're in a float condition the pull-ups bring
the pins up to a logic high level.

Thats exactly what my code is doing, or at least supposed to do.

I cant set all the ports to float because I am only interest in 6 pins across two ports. I supposed I could use a output_float for each one, but that should be what this is doing:

I don't see any code where you actually write to the port registers
(portb or portc). Your code only writes to the TRIS registers.

Ideally, you should post a complete test program. Then we can
see everything you're doing, including any #use statements.
