What is a Compiler? - Electronic Circuits Projects Diagrams Free

Suraj143 · 25th April 2008, 09:36 AM

Hi all I need some information’s regarding “C”

To program in C what are the requirements?

Theirs something called compilers what are those? They are so many compilers. Why not use only one compiler?

In MPLAB MPASM is built in to assemble the ASM code. But are their any compilers built in to compile C code in MPLAB?

Yes. You can use C compiler to compile C codes into asm, then from asm assemble to hex.

Some C compilers even put out the HEX file directly

Ok now what I understood is a compiler means "It is a program that translate source code to an object code (output code)"

My question is why there is so many compilers? Why not use only one compiler?

Why are there so many cars, why not just make one type?.

Why isn't everyone using PICkit 2? Why are there so many programming software / programmer out there? Why are there so many electronics forums?
Get what I mean?

Hi very funny

When doing in assembly language we didn't find any assemblers.MPLAB comes with MPASM & all did with it.

But when it comes to "C" many people asking what compiler using?

Thats what I mean.

hi suraj,
IIRC, MPLAB also have a free 'C' compiler and its well supported with libraries etc.

Suraj143 · 25th April 2008, 10:37 AM

A car of course you can drive it to a place.But the final output is the place that you go.

It means can I use any compiler to compile a C code?

Then what about other computer software engineers? They also writing computer port drivers in C can we use their compilers also?

Hi Eric I dont know what is IIRC?

Its a lazy way of saying 'If I Recall Correctly'

On Google search there's a full set of these abbreviations.

I see now only I got that, thats in short form I thought some sort of software.

Thanks for that

You need to use a compiler that produces machine code for the processor in question.

Also MPASM isn't the only assembler for PIC's (it should be - why produce a different one?), Parallax did one years ago using a strange kind of 'macro' language, and TASM is a shareware assembler that can assemble PIC code (but the source needs to be different).

Oh I see then the Microchip decided to include the best assembler to their MPLAB that is MPASM.

Likewise C compilers also easy easy inserting to the MPLAB ex:HitecC,CCS etc...

FWIW

The compilers we to generate code for our micro controllers are know as cross compilers.

Wikipedia:
A cross compiler is a compiler capable of creating executable code for a platform other than the one on which the compiler is run.
