That could work... Those are typically called "callback" functions. Note that there is a tradeoff with doing that: Because a function will be called in an ISR, the ISR prologue and epilogue will be bloated out because of having to save/restore a lot of registers. Just a warning. _______________________________________________ AVR-GCC-list mailing list AVR-GCC-list@nongnu.org http://lists.nongnu.org/mailman/listinfo/avr-gcc-list
