what is the difference

[HATHA]

hi all
in microchip site there is a c compiler(PIC18, PIC24, dsPIC DSC, and PIC32 families) for free its called

MPLAB C Compiler for Academic Use

and they claim that it is

fully functional, with all libraries and source code as commercial versions

also

These compilers are open-source

is any one have experience with these compiler(s)

thank you

A number of us use the C18 compiler. I think at least one person is using the C24.

They work.

nice to here that

so you use that free full function c compiler (not Free Evaluation Versions )

i mean this compiler(S)
**broken link removed**

not
**broken link removed**

just i want to know the differnce btween two of those free open soruce compiler and free evaluation version compiler

thank you

The two pages you provided seem to outline the features of each; I would suggest looking at that.

Features
Key features of the MPLAB C Compiler for Academic Use (LITE) include:

* ANSI-compliant
* Free, fully functional, with all libraries and source code as commercial versions
* Integrated with MPLAB IDE for easy-to-use project management and source-level debugging
* Generates relocatable object modules for enhanced code reuse
* Fully compatible with object modules generated with MPASM Assembler, allowing complete freedom to mix assembly and C in a single project
* Interrupt code can be written in C or assembly
* Flexible memory models take advantage of small memory applications and the storage of data in SFR space
* Strong support for inline assembly when total control is absolutely necessary
* Super-efficient code generator engine with multi-level optimization
* Extensive library support, including standard C, math, DSP and peripheral libraries
* Additional software libraries and application development tools are available from Microchip’s web site
* GNU-based, open source code (except PIC18)

Microchip Compiler Features:

* ANSI compliant, with standard math, memory, data conversion and math libraries
* Generates relocatable object modules and libraries for enhanced code reuse.
* Optimized to generate as much as 30% less code than other commercial compilers
* Strong support for in-line assembly when total control is absolutely necessary
* Allows complete freedom to mix C and assembler modules in a single project
* Extensive libraries including Microchip peripheral libraries
* Multiple optimization levels
* Full user control over data and code memory allocation
* Full interrupt support
* Free Evaluation Versions (below)
* Free upgrades
* Download free unrestricted use student editions and the free MPLAB IDE at Microchip Technology Inc. - a Leading Provider of Microcontroller and Analog Semiconductors

ok, is that mean C Compiler for Academic Use doesn't have code optimazation as in as commercial versions. mean same code written in two compiler take different space in code memeory ?

After the trial expires yes.

If you're writing mega code for commercial use then buy the compiler. That's the idea behind a student edition.

The C18 is not open-source I think the rest are

hi

that is
LAB C Compiler for Academic Use = kind of Evaluation Version & have trial period ?

The C18 is not open-source I think the rest are

microchip mention about that in their web

what so ever thank you frieds for the explenation
