Hi,

I bought the PIC kit 2 programmer and i am trying to figure out how to use the compiler. I'm going through the manual for HI TECH COMPILER that I am using to try and compile C code to assembly language. The steps tell me that I need to open the 16f887.h header file, but my micro controller is a 16f690.h. First I can't locate that file, and second what exactly does that file do?

 

i meant my microcontroller is a 16f690 and im looking for the 16f690.h header file**

 

Go to the install folder for your compiler. Then locate the quikstart.pdf in the doc folder. Here you will find out how to start a new PIC C project. You will not need to include other than htc.h file. You will not find a include file for 16f690. Since 16f690 use the pic16f685.h file. The configuration bits setting is in the end of this file.
Which version of the HI-Tech C compiler do you have? Then you download mplab from Microchip. You will download the current version of HI-Tech C compiler also.

 

okay so i did what you said, now when I try to build it gives me the following error messages.

Error [800] C:\DOCUME~1\ironmike\LOCALS~1\Temp\s36k.; 45. undefined symbol "LVPDIS"
Error [800] C:\DOCUME~1\ironmike\LOCALS~1\Temp\s36k.; 45. undefined symbol "DUNPROTECT"
Error [800] C:\DOCUME~1\ironmike\LOCALS~1\Temp\s36k.; 49. undefined symbol "BORV40"

I tried looking through the manuals and I'm not sure where these symbols are located. Any insight would be helpful...

and the version is 9.70

 

Go to the installation directory of HITECH PICC. Then go to the "/include" folder. You'll find the file you want there!

 

You will not need to include other than htc.h file. You will not find a include file for 16f690. Since 16f690 use the pic16f685.h file. The configuration bits setting is in the end of this file.

Make a template file and paste in the configuration bits setting as a comment on the top

as you can probably tell im not very experienced when it comes to programming, t06afre the code you gave me where should I post that in to? Is it the source file or the 16f685.h file?

Thanks in advance this is kind of coming slower to me than i thought

 

The code I gave you is as shown in the post only a comment as it inclosed by /*.......*/
You can paste it in at the beginning in your code. Then you pick items from it to construct a __config statement like this as an example

__CONFIG(INTIO & WDTDIS & PWRTDIS & BORDIS & MCLRDIS & FCMEN  & IESODIS & UNPROTECT);

It is taken from the pic16f685.h file in your compiler include folder. But in the pic16f685.h file those statements are not only comments

 

I think im in over my head here as I have never done this before and I feel like im lost even setting this up... I would like to get a book thats eazy to understand, can you point me in the right direction... there are tons of books on amazon but maybe there is a different place to start maybe online?

Thanks for your help, its just hard for me to grasp all this, but I would really like to learn the basics before I go on.

 

Then you start learning programming C on a PC. You really do not know much about what is going on inside the PC. But then programming a MCU it is very important that you do know something about the internal architecture. The data sheet will tell you all you need. So this must always be present then programming. Your original problem was the setting of the configuration bits. You will find all you need about them in section 14 of the data sheet. Then you map that information to what I already have given you, and you will understand.
It is also important to start simple in the beginning. Start with simple things like turning on and off LEDs.
I also think this book will help you http://www.amazon.com/Beginners-Guide-Embedded-Programming-Microcontroller/dp/1438231598/
By the way download the latest PICC from here. It has some important bug fixing like problems with the __delay_ms function
