MPLAB C18 Student auch für kommerzielle Benutzung?

Warum liest Du nicht selbst die Lizenzvereinbarungen der Software, die 
Du benutzt?

"Student Edition/Demo
The Student Edition is free! It has all the features of the full 
compiler and libraries. After 60 days, the optimizations related to 
procedural abstraction and to the extended instruction set of the newer 
PIC18XXXX devices will be disabled. Code compiled after the expiration 
date will function but may occupy more memory space."
