i got an error thats said

Code:

In file included from sketch_feb14a_pde.cpp:8:

the line it highlihted is

Code:

  DEBUGPRINT("\nHT1632(%d) ", chipno);

does anyone know what this error is/ how to fix it. im using ide 21 win7 arduino duemilanove.
please help.
thanks

What are you trying to compile?   Based on just the error messages, you are missing binary operator before token "#".....

[Reply #2 on:]

We need your entire code. What is debugprint function? Which library does it come from?

[Reply #3 on:]

I'm using code from
http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1225239439/8#8

and using it to code a duelmilanove to run a 8x32 led board.

the code was orriginaly intended to run a 16x24 led board but with some revisions from
http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1255052510
it should work with the 8x32.

i get this error when trying to compile. any information would be helpful.
Thanks.

but with some revisions...it should work with the 8x32.

So, the code you got from that site is not for the hardware you have. So, you made some changes, won't show us your revised code, and want us to help you figure out what is wrong.

I don't think so.

Post your code if you really want help.

[Reply #5 on:]

It looks like you're not #including the "ht1632.h" file, where all those symbols are defined.

[Reply #6 on:]

oh my bad, i will post the code i am using in a moment i need to get on to the other computer to open it. do you want just the .pde? or both the .pde and the .h?

[Reply #7 on:]

Start with the pde file.

I copied and pasted that code in a new sketch, and tried compiling. Got lots of errors. I followed the link to Reply #8 in the thread in the old forum, and copied the contents of the .h file. I created a new tab, and named the file on that tab ht1632.h. I pasted the contents into that file, and selected the Verify button again.

Binary sketch size 1956 of ..., with the board set to Arduino Mega 2560. I got similar results, although a smaller sketch size, with the board set to Duemilanove.

Looks like the problem is how you pasted the .h file contents...

[Reply #10 on:]

ok ill try repasting the .h

[Reply #11 on:]

That was the problem. thank you for trouble shooting. i have another question though.  when i verify, then upload it should just run the graphics on the display, correct?  it's receiving power from the computer.  do i need to unplug it from the computer and pug it into my ac/dc adapter?
Edit: i pluged it into the wall. it made no difference.

any suggestions?

[Reply #12 on:]

If everything is wired correctly, I guess it should.

[Reply #13 on:]

ok, i tested the current and its running. i have the wires pluged in the way they should and nothing is happeneing. need help. any suggestions?
