Hi Friends,
I have started to coding with HI-TECH C compiler.I have used MPLAB IDE.
Please,tell
1.Is HI-TECH C a compiler? And,Is MPLAB a IDE?(don't write more,please tell Yes or No )

2.Am i correct that compiler settings in MPLAB?(tell more about this ) 3.I coded small project like this.But,Compiler give me "Build Faild" Please,give me some example code or links.

1. Yes and yes
2. Seems correct. Not sure since I normally use C18 compiler.

3. Seems like you didn't include the header file.
Under the projects tab in MPLAB expand your project. Then right click on header files and select "add existing item". Navigate to where you installed your compiler (not sure about hi-tech compiler but for C18, it's C:\Program Files\Microchip\mplabc18\v3.40)
Then there will be a folder full of files with the .h extension( header)
Find the file that says - PIC16F877A.h or something similar and add it. It should compile fine.

Nadeeja.

There is no problem with the include file,

Normally in a IDE we setup include path for give the support to the interlaser or if you keeping 16F877.h in your project, [when you add it to the project , I think it MPLAB will copy it to
your project working source directory, or pass the include path the the directory, in that case.
will work.

So use try the first choice I have given. Then it will search default include directory.
I'm pretty sure you lack this line.

These things are non magic. your compiler is already working. Only thing is when you didn't add that include
file as a project file, the second choice won't work.

Anyway read the manual, manual is not to forcefully to keep in mind like periodic table, it's for reference.
Manual describes how to setup the include path,library path ,linker scripts , templates and etc. When you
got some time read it.


Contaz, your compiler is working fine , otherwise it won't give this error messages like this, note your
simple mistake on ';' thing. After the while.

1.Is HI-TECH C a compiler? And,Is MPLAB a IDE?(don't write more,please tell Yes or No )

Yes

2.Am i correct that compiler settings in MPLAB?(tell more about this )

Correct. See Neo's great Microcontroller tutorial How to start with Microcontrollers.

3.I coded small project like this.But,Compiler give me "Build Faild"

Two problems.
1. You need to put, #include <pic.h>. In some HI-TECH compilers, you need to use #include <htc.h> instead.
2. Loop has a syntax error. You need to put a semicolon after while(1).

Your corrected code will look like below. Please note that I hate to see codes with bad indents (correct tabs). So please be kind enough to maintain indents correctly as pasted in my code.

Fox,SemiconducterCat and ZevenZero,thanks all for help me...

According to Fox said,I could found .h folder of HI-TECH C Compiler.In my machine,path of it is "C:\Program Files\HI-TECH Software\PICC\9.70\include".This folder has lot of header files(189) and one text file(readme.exe).
But,pic16f877a.h or pic16f877.h not exist.
in readme.txt has this text.
[/color]
Therefore,I included htc.h file for my project.But,Now has other Error in building.

It's not pic16F877.h it's "16F877.h

But Use htc.h as sevenzero told.
And sounds like Delay_ms() is a macro, and that macro needs you to define your oscillator
frequency.
correct value may depend on your crystal , I have configured it for 4MHz.

Since htc.h or pic.h are general include files you need to say your crystal frequency
in order to generate that macro.Otherwise it will be a undef.



EDIT: Ops you're using lite edition right. I think you need to do a helder file injection in
this case. Dig this http://www.edaboard.com/thread210298-2.html , sounds like you
need to write your own.

And sevenzero, are you on complete version of Hi-TEch c , can upload the delay.h ?

How am I define my oscillator frequency?
I included your code like this.But,Not change...
however,How am i use this Library function in my code?
is library function equal to macro?

I asked you to go though Neo's How to start with Microcontrollers tutorial. Everything you need is there.

You need to make those delay files and include the delay.h.

Within delay.h, notice #define PIC_CLK 4000000 //4Mhz. That's it!

Try define FCY thing above the include.

To answer your question about macros , you need to turn a C++ book up and read a chapter about
Preprocessor. Functions or inlines are better than macros. But still we can't live without preprocessor.
It's not possible to live without preprocessor.

But I think here the real problem is the lack of delay.h in your lite edition. I think sevenzero could post
his one. So you could do this injection.



EDIT: Neo have that already, Yes add that delay.c and delay.h to your project as neo told.
So sounds like we all using lite edition right !

Try define FCY thing above the include.

Nothing like this for HI-TECH C. Semi.. is messed up with another compiler.

macros

That's nothing complicated.
#define ADD(A, B, R) R = A + B;

So if you call ADD(5,3,ret), precompiler will replace that line with ret = 5 + 3; before compilation. That's simple as that.

But I think here the real problem is the lack of delay.h in your lite edition. I think sevenzero could post his one. So you could do this injection.

There isn't any delay thing built-in to HI_TECH C. You need to write something by your own or else found someone else's.

EDIT: Neo have that already, Yes add that delay.c and delay.h to your project as neo told.
So sounds like we all using lite edition right !

No. It's not because of Lite Edition thing. You will find a delay under samples in Standard Edition but it is completely different to what Neo has added. So it is that you need to write what you need as you need with HI-TECH C. Nothing built-in including the processor definition file.
