I am not saying BoostC is not good. I have not used it.Ya. After that it's a limited demo or cough up 500 clams. Ouch!
I'm stickin with BoostC. Only $75 for a compiler for 16F, 18F and some 12F's. Great deal!
Why are we even talking about this? The free C18 works but does not optimize so you use more flash. In the few cases where you need more flalsh buy a PIC with more memory. Same for speed.
