Hello,

Is there a Pascal compiler for Ardurino (instead of the existed build in language or C) ?

Thanks,
Ido

Don't know anything Arduino specific (their forums seem to be overrun by C language nazis), but for the AVR micro controllers in general I know of 3 commercial products:

mikroPascal Pro (http://www.mikroe.com/mikropascal/avr/) Embedded Pascal for AVR (http://users.iafrica.com/r/ra/rainier/pAVR.htm) Pascal-scm for Amtel AVR (http://www.e-lab.de/AVRco/index_en.html)

All three have some kind of evaluation version, however usually limited to 4KB or 8KB of flash code

There used to be a free (no open source AFAIK though) "Pheline Pascal AVR" (http://www.mikrocontroller.net/topic/140480), but that hasn't been maintained in years (and is German language only)...

Thanks

FPC has an AVR target (the processor the Arduino is based on), but I don't know its state... (AFAIK its non working though :( )

I know there is an entry in the FPC Wiki about that, but that is quite "aged" and I am not sure if FPC in general is a good match at least for the lower end of any micro controller (not only Amtel AVR but PIC's as well), given that some of them are very limited in the amount of usable RAM/stack space and usually do not have any float support either...

That's another question of course. But e.g. Florian tries to minimize the overhead of the embedded RTL and if you are aware that you shouldn't use high overhead features they won't be linked in either (e.g. if you don't use Variants then the variants unit won't be used).

Also currently there is no PIC support for FPC, but there are some that seem to be interested in implementing it.

Those micro controllers aren't easily comparable to "mainstream" processors of the x86 line or even ARM(v6/7/8) or M68k, etc... You need to have quite some kind of knowledge of those little buggers, probably causing as many headaches as those CPU targets like MIPS, with nothing coming up quick.

I am kind of disappointed to see that there isn't a decent free (not necessary Open Source) Pascal compiler for Arduino/Amtel AVR, but at least as far as the 8/16bit PIC micro controllers are concerned, there is a very nice "Turbo Pascal" like compiler called PIC Micro Pascal (PMP) available from a nice French guy called Philippe Paternotte at http://www.pmpcomp.fr/

In our previous episode, Ralf A. Quint said:

If one is afraid of overhead, I would simply buy the vendor recommended compiler. Many of the 3rd party alternatives are less optimal too. At least they are with (ds)pic

Well, as far as the micro controller vendors are concerned, those are usually C and to some lesser extend, BASIC compiler's only. MikroElectronic has a not half bad Pascal compiler (though with quite a few bugs and quirks) for AVR and as I mentioned in my last post, for a lot of PIC chips, PMP is a quite decent choice if someone wants to stick with Pascal instead of using a different programming language. Not that anything in general is wrong with those C/BASIC options available, but it's simply a matter of preference of the basic language/tool to use... ;-)

I personally would like to be able to use FPC for some upcoming Raspberry Pi projects (which is an ARM v6/ARM11) rather than having to use C (though I am using C for +30 years now as well)

Considering that there are screenshots of Lazarus running on the Pi I don't think using FPC there will be a problem :)

Noting other peoples' responses, but I'm not sure that that's a meaningful question. "Arduino" is more a development environment and set of runtimes in its own right than a hardware platform and there is no direct Pascal equivalent, i.e. there's an AVR target but it won't have Arduino-compatible handling of the various I/O capabilities.

Hi,

Does it have to be Arduino ? Or just the formfactor ? I'm using an Olimexino. That has an STM32 cortex-m3 processor in the same formfactor. And I'm developping an embedded project with FPC.
There is also the maple, arduino form-factor but also a cortex-m3 processor.

Just my 2 cents ;-)
