Serial VB 2005 pic 16f877a problems

Valid for Timeout use...

Ayy......good point...
But what if the serial cable is 'amplifying' the unloaded pin, as in a floating input, and it ends up causing garbage to try to get into the SERIN statement.

How about adding a pullup or pulldown as appropriate?

He said he use MAX232

But yes i see what you mean.

ok, I took out the pause, added the #, so the serin now looks like this...
serin portc.3,t2400,10,mainloop,[#pcsig]
it still locks up,
i added a 4.7 pull down to rx, no luck
pull up no luck
serial cable still not even connected (just trying to get it to run first with serin command intact)
will keep trying
thanks

[mister_e]

nope... no square brackets in that.

how is this.........still does not work.
serin portc.3,t2400, 10,mainloop,#pcsig

[mister_e]

seems i'll need to try it here

can you post your missing class or your whole VB code please?

[mister_e]

and woops i just saw that...

serin porta.1,t2400,pcsig
if pcsig > 1 then high porta.1

you should use another pin...

and then

lcdout $fe,1,pcsig,"pcsig"

Should have another #

lcdout $fe,1,#pcsig,"pcsig"

First of all I would like to thank you again for all of your wonderful help. It is nice to know there are people like yourself and the other members of this forum in this world who devote so much time and energy to helping newbee's like myself.

I don't wan't you to go through all the trouble of re-createing my project unless of course, you want the code (it is a pritty nifty way of showing the temp in windows).

Besides all that is it possible that it is the VB code that is locking up the pic when it isent even connected when the pic program hangs up?

my next thing will be testing out the vb program on a basic stamp I have, if that works at least I know the vb part works, the next will be trying it out on a 16f84 and then if that works I will buy another 16f877 and see if it's the ic.

If anyone has any other sugestions or you still want the code let me know
Thank You
