Hi I am a beginner to PIC programming and have a PICkit2 programmer, I have downloaded MPLAB IDE v8.92. with the plug-in and CCS C Compiler, now the problem is I download *.asm files found on sites and tried several files but I keep getting Build Failed. And error as “Error[113] C:\USERS\USER\DESKTOP\HEX N ASM FILES\SERVO.ASM 74 : Symbol not previously defined (OSCCAL) Error[113] C:\USERS\USER\DESKTOP\HEX N ASM FILES\SERVO.ASM 77 : Symbol not previously defined (GPIO)."
As I am new and just started to use a programmer, I need to use HEX files but unable to understand why the ASM files on site are unable to be converted.
Please help me solve my problem.
 

Hi,

Have you set your Mplab Project up to use Assembler or C ?

Post your Assembly code here ( use the # tags) so we can see what you are actually using.
 

thanks barry.. need to know where to get these libraries.

They should be somewhere in the MPLAB install path. But as WP100 said, you should make sure your project is setup properly, and maybe post your code.
 

Hi,

The code builds fine in Assebler with Mplab V8.92, so there is nothing wrong there.

Do wonder what you are trying to program in ?

You say you have downloaded CCS C, but C is a different programming language to Assembly which that code is in.

In General terms the two methods do not mix.

Can you say what you intentions are...?

Assuming you want to compile it yourself, there are a couple of gotcha's to look out for:
1) Be sure case sensitivity is disabled.
2) Under "configure" in the MPLab screen, be sure to select your device.

Hi jpanhalt I just added the asm file to project and selected the right chip i,e: PIC12F629 and selected MPASM assembler(mpasmwin.exe)v5.51. so i am not sure where i am going wrong..
 

"OSCCAL" and "GPIO" are indeed registers, but unless case sensitivity is disabled, MPLab will not recognize "gpio" and "osccal." (As well as some others.)

Go to build options and check the box to disable case sensitivity. Then see what happens.

John

PS: If you use code tags here, i.e., {code}<insert code here> {/code} (replace curly brackets with straight brackets), your formatting will be better preserved. Cutting and pasting what you posted here gives lots of format errors that I ignored.

Hi I thank you all for your help and guidance in solving "converting *.asm to *.hex". files and highlighting the basic knowledge of using MPLAB IDE.
I also apologize for Inappropriate Use or Lack of CODE or SYNTAX Tags.
