Sir, I hope someone is paying you for your contributions here because you are, once again, a life saver.

In-very-deed, bug #14 in the errata A0 chip is the one I experience, and Microchip confirms ...

I've search the forums and couldn't find anyone that had this particular problem, so I'm posting it.

I'm using a PIC18F6722 with the hardware serial port. I declare the serial port like this:

#u ...

After several hours of development, I finally came up with a half-decent solution to the famous problem of easily accessing strings stored in ROM via the use of pointers. Furthermore, my approach perm ...

Now I've just spend the last two hours trying to pass a pointer to ROM to a function, using v4.064, and even though it compiles, it always produces gibberish.

I've tried so many things that I could ...

Yes! Thank you, it works.

I assumed the compiler required a character to do it, like most other...

I mean concatenation at compile time, not at runtime.

I would like to know if there is a way to do string concatenation at compile time, like:
In PHP i would do "blah" . "something"
In VB I would do: "blah" & &quo ...

Update:

Yes. That is exactly why. I just tried it with a blank test program and, indeed, if rom locations are specified, code is compiled. Otherwise, if function is not called, it's not compiled.
...

I understand your test shows exactly what should be happening, but why would a whole include file loaded with 5 functions that are never referenced to anywhere would still be compiled?

One thing to ...

I am currently writing code to add to my programs the ability to receive a new firmware through TCP/IP.

I made various elegant hacks to achieve this, such as faking boot code, freezing rom areas to ...

libor: Maybe, but generally I tend to avoid external ram or rom and it complicates things unnecessarily (emulator support? external flashing from ICSP? etc)

Instead of upgrading my platform with ex ...

SET: In my case, flash is a big limitation. I've hit the ceiling of my 128KB flash PIC, and the biggest pics they make are 256KB of flash, either in PIC24, PIC30 or PIC33...

kevcon: That is exactly why I'm using CCS at the moment. Great product at a very low cost.

kevcon: I am looking at it, but may move to Freescale's Coldfire v2 series due to lack of a compiler for pic24. (I have yet to evaluate the available compilers for coldfire, as I may be just as disapp ...
