Hey, It's version 3.1 but I think the error is more down to my program layout. Im basically trying to do this: Everytime a keypad button is pressed ( if it 9 or lower ) add it into a string.. So say I pressed 1,2,3.. I would have a string like "123". Then when they press the star key ( 10 ).. Check ...

Hello, Yeah I should of said limitation :P... Im a C++/C programmer so going from that to flow charts is strange, not being able to use == in If box's is a pane as well :P but i'll live... One more thing: I have made a program which compares an input to a password... I have password stored as "123" ...

Hello, I think I have found an error within the flowcode string manipulation box ( Flowcode version 3 studen edition with latest update. ) I had a string "output" and an integer "input". When I tried to do this: output = output + ToString$(input) it wouldn't let me.. So I had to create a third strin...

Hello,

I saw the last tutorial that uses the buttons instead of a keypad... I think I'll try and write a fresh one..

Thats probably my problem, Im doing everything else to the word.

Hello,

I also have this type of adapter, although I stupidly threw away the packaging showing what way to place the plug...

But I have found that the board accepts both. I can even remember reading some where that it does support both.

Hello,

Im still not having any luck with Flowcode, most of the components cannot be registered no matter what I do...

Is there a way I can get input from a keypad with flowcode even though I dont have the macros?

Cheers

Hello serstel,

I believe the board accepts both.

Hello,

I have recently purchased the 16F877A chip which alows me to use all 5 ports.. I have tried the LCD screen on each port with 5v+ on the lcd screen...

Hey Steve,

Ah interesting, I've seen various videos of them in action over the internet and an eblock for them would be pretty cool.

Hello Steve,

I resolved the other issues on friday, but the flowcode missing component issue is my only current issue... I'll try some of the things you have said and report back...

Many thanks for all the support,

Cheers

Another update:

I have made a program like this:

While 1

Out 255 port b

delay 25 ms

Out 0 port b

Delay 25 ms

End while

This gives me only 8 solid blocks on the lcd screen Hmm..

Hello,

Haha! It works

Thaks Ben!

Hello,

I had a thought, could vista be setting up devices differently than XP? Putting them under different "class's"... Did you use a USB library when writing the software? Or did you hardcode it all to specific locations?

Hello Again,

I have reinstalled PPP with the LPT port driver, and I dont get the service control error any more... Although It still thinks my board isnt connected via USB... All the PPP settings are correct for my board.
