 Bigger Bigger  Smaller Smaller  Reset Reset

hi there, I have purchased a VFD pn 03700-06-020, and I found a page in the Arduino playground,
http://playground.arduino.cc/Main/IeeFlip

this is what I have done so far, I've loaded the IEE zip file to the libraries, followed the directions carefully, and I am getting errors when I compile/upload to the arduino board:

 IeeFlip.cpp:231: error: prototype for 'void IeeFlip::write(uint8_t)' does not match any in class 'IeeFlip'
C:\Users\shop computer\Documents\Arduino\libraries\IeeFlip\/IeeFLip.h:140: error: candidate is: virtual size_t IeeFlip::write(uint8_t)

Now, I have fixed one of the issues that was brought up in the forum, I changed the Wprogram.h to Arduino.h, I was reading that the cpp and h files might be outdated, i tried fixed the virtual void to size_t as well, no go...
please help!
any help would rock!

I can't get either the "Hello World" or the Serial Test to compile using "File/Examples/IEE FLIP/[program]"
These are cool displays. I used one like this for my Junior project at DeVry. I didn't have to worry about
libraries because I was using an ET-3400 Heathkit uProcessor trainor. Don't remember anything about the
details but my advice to you at the moment is forget about Arduino libraries and see if you can interface
it as a serial display if it supports it. Mine was serial, but yours may be only parallel or both. If it is serial,
just connect the Rx to the Tx on your Arduino and use a serial monitor. I don't know what the baud rate
would be. If it is not serial.  Just try to get it working without using the library. Have you grounded the "Test"
pin yet ?  Just try to write to it following standard parallel interface procedures and using the datasheet.
It's just a piece of hardware. If it is functional, you should be able to write one character to it .  Maybe
somewill can tell you why it is not compiling. If it were me I would add a uart to convert serial from the
Arduino to parallel to the VFD.  To me that would be easier than dealing with parallel port writes.
Maybe someone else has some better suggestions.

Hi there, I tried the hello world one as well, that is where the problem is, mine is parallel only, no serial involved. Yes, I have tried the test function, the display works great! for these are brand new, hmm I will try a uart to convert over,,,I wasn't thinking about that btw. I'm mostly a PIC guy myself, but I keep hearing about arduino, so I've decided to join the club and see what all the deal was about. I'm new to Arduino, but it seems pretty easy, so far...

I will try to write it to the datasheet, there's a few things that I get confused, that is why I bought 2, in case I fry one,,,lol I will look on Google re. parallel interfacing via PIC as well...
thanks!

Post the datasheet.
This is an international forum.
I have no C++ programming experience and I was downloading and running programs for almost
a month before I actually sat down and wrote one myself ! One of my best friends is a PIC guy
and he suggested Arduino to me because there is so much free SW and project info. If you have
an UNO almost everything works. I been into ArduinoLand (as I call it) since last Oct 30th and now
I have 3 UNOs , 2 Pro-Minis, 2 Atmega328 chips with the OPTIBOOT bootloader pre-installed
(so it works just like an UNO except you need the FTDI BASIC USB to serial adaptor to load programs).
I also have 3 or 4 ATtiny85s (8-pin DIP, 8-BIT uProcessor, programmed with Arduino UNO SPI
interface. I just programmed one as a Police Cruiser Lights LED simulator with 2 blue leds and two
red leds that flash super fast.  I've actually only written a half dozen programs. All the other projects
were plug & play, but sometimes you have to make a few changes . There's a huge pool of
"Tribal Knowledge" here on the forum because it is international and sometimes you get lucky.
Some people are difficult to deal with but all in all it is much better than being left to do it all
on your own. In your case, you have a known good working piece of equipment and if you
post the datasheet (rather than posting a link, that requires extra work) you may luck out and
find someone who can tell you exactly how to get it to work.  I  would focus on getting the serial
to parallel Uart thing happening and you need to configure the UART for the correct baud rate for
your serial monitor. If someone can tell you how to get the library to work you may not have
to use the Uart but that's what I would do.

WOO HOO! she's working! i figured it out, after much reading and many visited sites, I found that one guy had a simular issue, he said he downloaded an older version of Arduino 0023, after pin relocating on the board via the program, bam, NOW it works!  smiley-lol

That's great !
You should post the details. If you can post WHERE you got the display and where you got
the Ver. 0023 and what pin change you made.
They like to document thkngs well on this forum.  They don't want the
same issues coming back so they want to be able to post a link to your
explanation of the solution.

Man these displays are not cheap !
Where did you get yours ?
How much did you pay?
I'm thinking about getting one but I don't want to go through what you did . What's the trick ?

Did any modified library for this ever surface, I'm haveing trouble with mine as well. I updated the "wprogram.h" in the .h and the .pp files what else do I need to do?
