Automated device select in PCH
PostPosted: Thu Aug 31, 2006 12:53 am     Reply with quote
I use PCH inside MPLAB. I have applications that support multiple hardware platforms. Currently to compile an image I set a flag in the source code to select the target platform plus select the target PIC from MPLABs configure window. How can I embed the target PIC info into the source such that I do not have to manually reconfigure MPLAB each time I select a new target platform in my source code?

Code:

#define HW_PLATFORM 1

#if HW_PLATFORM == 1
#include <16F648A.h>
#else
#include <otherdevice>
#end


Something like this?

You can also throw in fuse lines device lines etc into the various blocks...

This was the mechaism I tried but it does not work correctly.

For example if I specify a PIC18F8722 both in the code (as per your example) and as the device in the config window the code compiles correctly however if I select some other 18F family processor in the configure device menu like a PIC18F24J10 and select PIC18F8722 in the code then I get an error message of the form "The Extended Mode Configuration bit is enabled but...."
