compilation problem

[yasotha padmanathan]

hi,
i hv build a coding i hv downloaded from cytron which is the PR25 project coding. but the source file oni consist (.c) file. I cant able to edit the coding and build it coz it asking for the .h(header file) file....i dont know hw to solve this prob. any1 can guide me hw to build the program successfully?

The <pic.h> is in your Hi-Tech C compiler directory inside "include" sub-directory.

Here is a tutorial on how to create a project in MPLab. http://tutorial.cytron.com.my/2011/08/18/how-to-create-a-project-in-mplab-ide/
Hope you can find a solution from there.

that tutorial was very2 helpful...thx alot for helping. I shall try it nw.

hi, i followed exactly like the tutorial but yet i encounter problem when building. still it says couldnt locate the pic.h file.

But you chose the wrong compiler MCC18 which is for the 18Fxxx family. You should select "HI-TECH ANSI C COMPILER" under "HI-TECH Universal tool suite" for the 16F877a.

BTW are you using 18F452 to replace the 16F877A in PR25 ?
Then that would be a different story.

hi, sorry its not the project25 but im doing the project is PR9, which is the password door lock. Im using PIC18f452. so which compiler i shud use? plz guide me..

[hyng]

PR9?? The sample code for PR9 is for PIC16F877A not PIC18F. It is mentioned in the description. You cannot direct use the sample code if you are using other type of PIC. Have you modified the code according to PIC18F??

[yasotha padmanathan]

i didnt modify the code. but i did sum trial 1st. Im in a cofused state because i learned tht dat code used for pic16f can be used for pic18f as well..juz need to modify sumthing rite.

Yupe. You need to modify the code. Most are the SFR names and address. You may refer to the datasheet.
BTW, i suggest you to go through some examples of PIC18F source code so that you know how to start.
One of the example that you can refer is the sample code of SD02B by using 18F4520 at the product page below:
