MPLAB C Compiler VS Hi-Tech C PRO Compiler

[redips_id]

I would agree with shiyan about the compiler differences. Even with C18 and HITECH compiler, there is a feature called optimization. This optimization will actually decide how optimize the C code is translate into assembly before turning into hex code. If the optimization is good, the hex code will be smaller in size and of course faster execution time. HITECH is well known for high code optimization.

Very good explaination, thanks ober, i'm clear right now.
Ok then, what is the best compiler for PIC? As I know we have MPLAB, Hi-Tech, CCS, MicroE n etc.. If Hi-Tech is the answer, I want totally focus on Hi-Tech C Compiler for my PIC programming, hehe..

The best compiler, economically wise would be the CCS compilers. It's much cheaper than the MPLAB or Hi-Tech but you need to pay for the annual maintenance. The annual maintenance means further program updates for only one year.

Hi guys... I'm new here and this post got my first reply

I still prefer to use Microchip C compiler (C18, C30, etc) and the main reason is all the Microchip's library can be compiled with Microchip C Compiler. Just my 2 cents

Thanks Brian for your opinion..

Actually I have tried MPLAB, Hi-Tech, CCS and MikroE.. What I mean best is on the compiler performance itself, which one is the best in code optimization (and other performance criteria)? I have read at another forum discuss about this topic too and this is one of the comment "The B Knudsen CC5X is supported by MPLAB. The free version supports up to 1K of code" what is meant by "supports up to 1K of code"? What about Hi-Tech? Sorry for giving a lot of question..

I'm busy on reading another datasheet, so I didn't have much time to read on PIC C Compiler manual..

Unfortunately, there is no formal benchmarks on these compilers at all, at the time of search.

From the CCS website, it seemed that their own compilers are slightly better than the rest of the other compilers mentioned.

I have no comments on those compilers, each of them have their own strengths and weaknesses.

My preference is, use the ones which contains optimized hardware/software libraries, and everything else in balance. It makes prototyping very easy.

I would recommend CCS but the program updates is only effective for one year. The CCS contains a lot of libraries and even an RTOS (Real Time Operating System) should you need to multitask on your microcontroller.

Thanks Brian

I interested when you are mentioning "Real Time Operating System".. Can I ask, which PIC have RTOS?

RTOS is a piece of software for microcontrollers/computers. The software enables multitasking in those systems.

The only RTOS I used b4 was the FreeRTOS. It supports PIC18F and above. Not sure for the others.

Been using HI-TECH for 16F and MPLAB C18 for PIC18F
