Hi all,
After a year's break I'm reviving my pic projects, this time trying SDCC
instead of c2c and I'm having problems doing pic-specific stuff with it.
1) How can I define an interrupt handler? I tried to mimic absolute
addressing syntax for variables and language extensions for other targets,
but didn't have much success.
2) How do I define the target pic? Is it the "#define __16FXXX" trick as in
the regression test sources? I tried that, but the resulting .asm still says
'include "p16c84.inc"'.
3) From where do the C .h includes for different pics come from? Were they
available for download somewhere or was it some tool that translated the
original gpasm-includes?
Any help or pointers would be greatly appreciated. If someone has example
code for the SDCC, it would probably answer most of my questions.
Cheers,
Antti
