Yep, Happy Christmas to you all, and have a very merry New Year.

(ahh Giles, the memories!)

Thanks for the tips jeremiah. I'll watch out for those things.

I must admit, I've never used reference parameters - I'm not much of a C++ guy so just haven't found a use for them yet.

It certai ...

Thanks Ttelmah - much appreciated.

Thanks jeremiah,

That's exactly what I wanted to do. I did try to use pointer to pointer syntax, but I didn't get it quite right. I was using MPLAB sim to help me understand the C but it was flum ...

Hi Ttelmah,

Sorry, I didn't make myself clear: I have edited my first post to correct my simplification of function names. And you are correct: I did intend to call func2.

I do understand what ...

Hi guys,

I thought I had a reasonable understanding of pointers until the following problem popped up:-

void func1( void )
{
int8 * srcDataPtr;

// Set up pointer ...

Could be anything: your circuit design/layout, power rails etc.

However.. sounds like it could be an uninitialised variable in your code. Very easy to miss.

Ahhhhh, I see. Now it becomes clear! Sometimes, Google just doesn't cut it!

Thanks to all who replied to my probably fundamental questions.

Once again, I'm surprised and glad that busy and obv ...

Thanks for the comments so far guys; very interesting.

I know I'm labouring the point but why doesn't the following produce an error?:-

#include <18f46k22.h>

#fuses INTRC_IO, NOWDT, BRO ...

I've obviously got the wrong end of the stick then, especially regarding compilation.

My understanding was if all other functions were after the main they needed to have function prototypes.. is th ...

Ahh.. but the code still runs without errors even if I comment out the func1 prototype... surely this isn't correct, especially as it's after the main function?

And I am using func1.. I'm calling ...

Thanks for the advice. However, I have played around a bit and found that even in a single file, you can still circumvent the system...

If you do the following:-

#include <18f46k22.h>

Hi all,

I'm creating a large project with multiple files, in the usual CCS approach of one main.c file which includes the other files in it.

The main thing is, where do I put the function protot ...

Yes, but NOT in the INT_TBE (Uart transmit interrupt).

Which interrupt are you currently using the fprintf() function?

Use:-

printf( functionName, cstring, values )

.. in the f ...

OK, sounds like you'll have to re-prioritise your code.

If, the rest of your code can take a back seat when the ACK is needed, then I would say to follow my suggestion of buffering your ACK bytes f ...
