This may be a real good idea, because I have been using SDCC for a couple of weeks. I am using it for 8052 coding. Beware, the compiler I have (version 2.3.0) has bugs (as I'm sure all compilers do). However, these are not small issues. The "loop induction" optimizer made a mess out of some code I wrote ( a three deep nesting of for loops). It also seems to have issues with pointers to pointers. If you're pulling your hair out, and can't find anything wrong with the code, look at the .rst file (shows relocated/generated assembler output) and the .map (load map) file for problems. I wasted a whole day on this. Still, it's better than writing assembler all the time. michael brown -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
