Pic16f886

[Gerhard]

Hi.

Can any body please help me. I just started working on Microchips for a university subject. I seem to have problems with the header file of the 16f886. When I try just to test building it, there's an error report saying build failure. It points to the header file at line 2.
Any help would be apreciated.
Thanks

Here is a bit more info.

I am workong in MP Lab v7.4 and PCWH v3.227.
The header file i used was not available so i downloaded it. The error report is as follows:

And so it goes on and on until it says build Failed. I just wrote a simple while(1) loop to check if build would suceed.

Your version of the compiler doesn't support the 16F886.

Adding the header file (16F886.H) won't add support. There has to be
a record in the Devices.dat file for the 16F886. There also have to be
routines in the PCM.DLL file to support any peripherals that are different
(or new) from "standard" PIC peripherals.

Thanks but im very new at this.
How or where do i get the new compiler and what is the main problem, is it the PCWH or the MPLAB. I know its something silly but i am only starting to use microchips now so i have got a lot to learn.

The compiler is the main problem. Vs. 3.227 doesn't support the 16F886.

Also, MPLAB vs. 7.41 says it doesn't support the 16F886 with the ICD2
programmer, but it did work for me.

It would be easier to buy a PIC that is supported by your tools.
You could buy a 16F876. It's similar to the 16F886, and it is supported.

I downloaded the new version 4 demo but now it needs a .crg file. It says mine is to old for the newer version. What does that mean?

Thanks for the help

[Gerhard]

didnt see the last part of your reply.

Our specs for our 3rd year project says that we have to use the 16f886. I have got another pic kit but i am not alowed to use that one.

The demo doesn't support the 16F886:

Thanks for your help.

I try using the 16f876 and see if the prof's will allow it.

I tried building on that 16f876 but it also delivers the following error.

Whats am i doing wrong??

[PCM programmer]

You're probably erased your installation of vs. 3.227 when you installed
the CCS Demo (maybe). The demo doesn't support the 16F876.

Thank you very much. Now i can start programming robot wars car.
