Unknown device type
PostPosted: Mon Jan 05, 2009 11:17 am     Reply with quote
Hi Guys...

I know this topic was discussed several times before in this forum, but i have not found exactly my problem.

I'm using MPLAB IDE 8.10 and I tried a simple program:
Code:
#include <18F4550.h>
void main()
{
  while(1)
    printf("Test");
}


And the Compiler Log only says:
Executing: "C:\Programme\PICC\Ccsc.exe" +FH "main.c" +DF +LN +T +A +M +Z +Y=9 +EA
*** Error 24 "C:\Programme\PICC\devices\18F4550.h" Line 2(9,19): Unknown device type

So when I change my device to 18F4520 and also change the header, the Compiler log says:
*** Error 24 "C:\Programme\PICC\devices\18F4520.h" Line 2(9,19): Unknown device type Limited compiler version

And that is OK because I know I have a limited version!

Further I have to say that i use the PCH-Compiler (and it is the Compiler for the PIC18-Devices... Isn't it?)

So where is the problem? Why isn't it working?

Where did you get your compiler ? Do you have the demo ?

The demo only supports the 18F458 in the 18F-series. It does not
support 18F4550 or 18F4520.

I have an educational Single Chip IDE Compiler actual for the PIC18F4550.
Because of that I think it is right when i choose the PIC18F4520 in MPLAB that there is the message: "Unknown device type Limited compiler version".

But why does the PIC18F4550 not work?

You have the full CCS IDE, except that it's limited to the use of the
18F4550 only. Now you want to use MPLAB as the IDE, perhaps so
you can use the simulator or one of the Microchip programmers or
debuggers.

CCS has a brief FAQ article that says you can invoke MPLAB from
within the CCS IDE:

This thread has instructions by ckielstra on how to directly use MPLAB
as the IDE for PCWH, without having to first start-up PCWH.

The "plug-in" that he refers to can be downloaded on this page:
