Arduino TLC 5940 16-Bit I need Code Help!

A couple of things that may help though I am not an Arduino expert....

1) The errors appear to be quite consistent and clear that you have not declared many variables correctly (which may or may not clear up all the errors, but they should clear all the "not declared etc" ones). Your compiler manual should help you further to eradicate these errors, so read through with regard to error codes.

2) You have not posted your code that causes the errors (I know it may be big but not all of us studied under the great detective Hercule Poirot!! Also, my Crystal Ball is at the cleaners....!!

3) There are a number of great yahoo blogs for PICs and Arduino chips that you should join and ask your questions of.

4) I also keyed in "Arduino" as a search on Google and got hundreds of hits that should also help you, in several languages too......

5) If you have not followed slavishly the folder names and positions for the compiler libraries, it is also possible that may have something to do with it as well, check your folder structure carefully.

6) Are you using Windows? Which one? That might help an Arduino person here further....

As much information as possible will generally help better than the small amounts you have supplied.

7) If the program you are trying to compile is really big, then pick something tiny to start with, assemble that and if errors are produced, try and find them or ask here again. Start small.....

8) On "Instructables" there are many Arduino projects, start here and search with the name "Arduino" for example:-

http://www.instructables.com/

hmm

There have been some tips from Arduino people that looked more than respectable with regard to the errors. Try and follow their guidance......

Arduinos are generally fast chips and have lots of things going for them, (good marketing is also one of them!) but the other chips I mentioned are both very cheap, even in comparison to the Arduino, still fast enough (especially some of the newer ones) for both training/learning as well as many other quite involved jobs, BUT, their single best asset as far as you are concerned is simply NO COMPILING......

So no compiler errors either!! But the PICAXE Basic editor shows you errors when they are in your code often immediately as you key it in (but not always!), so sometimes you know exactly WHERE the error is!!! No searching.....even if it only happens when you run the program the line in error is displayed.....

But having said that, I have still scratched my head a few times about what was wrong.....generally the problems for me was that you try and do something that a PICAXE can do, but not the one you are using at the time!!........done that, been there and got the T-Shirt.....

I certainly am NOT a code expert on ANY chip and I have only read about Arduinos on the web.......but I manage to fumble my way through the bits and pieces I need, one time with online help from PICAXE (Nice folks and very helpful!!). I am NOT a programmer, though I also used to program stuff over 30 years ago.....never been trained is probably what I mean!!

By the way, I have no financial involvement with any of the companies mentioned.....

The code definitely seems to want those variables, but dumping a bunch of "unsigned int PB1, PB2..." or whatever into it will likely not produce the desired result. You need to figure out why they are expected but not present. One possibility is a missing #include file.

All of those "variables" are actually chip specific macro definitions for pin numbers in IO ports... PB1 is pin 1 in port B, really just 0b00000010 (i think... maybe 0b01000000, but regardless it's just a number)

in laymans terms... you dont need to define any of those things.. you need to

#include <avr/io.h>

but the fact that the arduino environment isn't doing this behind the scenes means something else is broken too.

Reinstall the arduino program first.... then make sure you are telling the IDE the right board you are using...... then try the include above......

it didnt work :( sorry

Here is the code I forgot,sorry. :)

If anyone can run this code and it works let me know please and what OS your runing and how your compiling it. I use windows 7 Ultimate with 018 Arduino software.

I have ran other programs like "Blink" and works fine. so I know the uploading is working. I have all the updates for Java software. I did the updates still no dice? so will this work on linux? maybe it doesn't like windows? I wish this would work. :( Thanks for everyone's help so far with this issue. I have see or website's state the same issue,I just want a working LED fader for my Arduino Duemilanove. Any idea's?

DRewwwwwwwwww

I'm no programmer so I dont know how to fix this.

If your TLC5940.h file actually looks like it does in your post (all crammed together with no line breaks), then that's your problem. You need an un-crammed version because the C pre-processor (which also runs in a C++ project [more or less, I think some C++ implementations use a pre-processor with slightly different rules]) cares about end-of-lines, though the C/C++ compiler doesn't.

Assuming it's just the CR4 editor doing it to the code, I loaded it in an editor and tried to parse it out. That can get tricky, but any self-proclaimed C guru should be able to manage it. I didn't see any problems with #if and #endif. Frequently, this error is caused upstream of the message. So look at tlc_config.h and make sure there's exactly one #endif for every #if (or #ifdef, #ifndef, etc.). If that one checks out, look at avr/io.h.

Or, you can follow AG's advice and start with a Basic environment.

It sounds like you are a beginner (no harm in that, we all have to start somewhere!), but maybe the Arduino chip is just a tad too complicated for you at this time (this could be a week or even a month too soon. Or even just a day or two!).

As you do not appear to have a local mentor, may I suggest that you either make a start with the PICAXE or the KiChips, sort of walking before you run.....

Look here:-

or here:-

They are compatible to each other, provide a "built-in" Basic interpreter (no need to compile till you learn far more), are fully software compatible to each other and are also probably the absolute cheapest way to get into PIC programming.

The program loading does not even require a programmer as the chips have a built in serial interface and can be eother downloaded from a laptop/PC with a serial port, or buy the Rev-Ed USB to Serial cable (one of the best and most compatible ones around, other ones may not work as they are maybe not 100% compatible to serial data) if you have no serial ports.....

Basic is a language that can be used in a simple way for beginners (I started with basic over 30 years ago at home with my first home computer, a Nascom 2), but can also produce very professional things too. Basically its as complicated, or as easy as you want to make it.....and no compiling!!!

Arduino is a (more expensive too!) version that you can come back to once you have learned a lot more......

A lot of the hardware is still compatible between all three if you are careful.....so all is not lost.

All the software that you need is free to download from Rev-Ed and it can also be run/tested, without even owning a chip, so you cn see how your basic program will (or won't!) run before investing even 1 cent!!!

I speak as though I am a PICAXE expert, I am most certainly not, but I enjoy playing around with these wonderful chips.....and things work, maybe not always the first (or second !!) time, but they do seem to end up working. Good for the soul!!!

There is also a PICAXE Blog on Yahoo with lots of help and ideas.....and many many firms all over the world sell the products.....cheaply.

Best of luck.....

Andy Germany,

your a life saver !! I downloaded the program and going to check it out. PIC axe is one of those chips i was gonna get and try out but Arduino is more powerful for the things I would like to get done. Thank you for giving me more INPUT #5 !

I was watching Short circuit last night. Anyways can you try to see if that program works or not? when I posted it the code got all put together. Each line was on it's own.

I got 5 TLC4950 chips sitting here on my desk and I got 5 TPIC6A596NE

I have a clue about Electronics just not programming. The Last computer(s) I programmed was a IBM model 4/25mhz and Atari 800XL/800 and TI-99 Trash80 model 1, 2, 3, 4 back in 1978.

Been doing ALL types of Electronics from one-end-to-next. My only thing I havent worked on was micro-controllers. so here I am starting. My first is an Arduino 328P-PU
