If I understood you correctly, and I am not sure I did, your push button switches ground the ports. If that is true, then yes, a pull up resistor, either internal (wpu) or external would seem to be in order. If your push buttons make the ports go high, then a pull down resistor would be required.Originally Posted by newbie

The VDIP2 might be different but on the VDIP1 the reset pin is left floating when not in use. Seems strange yes but....
Sounds like a bad conection or the magic smoke got out.

i tried what joe said and used a pull up resistor,. still nothing happend.. that made me hopeless about my module and began thinking that mackrackit was right..may be magic smoke did got out. so i ordered another vdip2 module and its on its way here..
for the mean time, i'm in the middle of programming the push buttons for browsing the files. how do i program the buttons to execute the command only after releasing the button from being pressed. the reason i want it that way is because if i execute the command(e.g. scrolling the lcd with the file names) while the button is being pressed,some files names would be skipped due to very quick execution.

If the button pin is pulled LOW in an idle state ,active HIGH. You could use WHILE/WEND.
Code:WHILE BUTTON = 1 DO SOMETHING WEND

sir, in my program which is similar to the code back in post #63,
the LCD prints:
Ver 03.66-123VDFCF On-Line:
then clears the display and then finally displays the filename that i wanted to display. I saved the characters sent by the vdip2 into an array right after the "DIR" command so the "Ver 03.66-123VDFCF On-Line:" should not be included in those characters because they were sent at the time the vdip2 turned on and long before the "DIR" command was made..but how come they are still being displayed?
how do i effectively display only the characters that are the response to the current command and not display the characters that were sent by the vdip2 long before the command was made?

That is interesting. Please post your current code so we are sure to be talking about the same thing.
Just a thought...
You might try more than one array and or clear the the array at given points. It should over write it but...
Need to see the code...

oh and one more question, is it really necessary to save the the array values into another byte like for this instance the x's? cant i directly use these array values to be printed to the LCD?
