I recently added support for the 12F617 to PICC8.05 for a small project
at home and it was rather more involved than I was hoping!
1) Create device header and add to the include folder.
2) Modify pic.h to include the new header if the symbol _12F617 was
defined.
3) Create a custom FLASH_READ() macro in pic.h just for the 12F617
variant.
4) Add device info into picinfo.ini in the lib folder.
At this stage I was hoping it would work, but it fell over during
compilation stating that a library file was missing "pic10--u.lib".
This target name was not even present in the library makefile...so
5) Edit sources\makefile and add pic10--u.lib to 'ALLLIBS'
6) Modify target picpph to create picpph.lib with CHIP=12F617
7) Copy picpph.lib to pic10--u.lib and move it to the lib folder (this
library uses the FLASH_READ macro created in step 3). This should
become clear if you examine the makefile.
This wouldn't compile if the FLASHTYPE was set to READWRITE_A in
picinfo.ini, but I only needed read capability so set FLASHTYPE=READ and
it all compiled and (somewhat surprisingly) worked perfectly, including
debugging. I had only a few words of program memory left by the time I
finished the project so gave it a good work out.
To add flash write capability to the library I suspect I would need to
edit flashcopy.c and recompile the library...or just create a flash
write function in my code.
