no book tips, but... what generally is called "multitasking" doesn't
exactly happen on a pic due to the stack restrictions, that's why most
books on the subject won't help much. multitasking on a pic is normally
implemented as some kind of a state machine (so look for something on this,
but it really isn't that complicated in principle), with the states
possibly influenced by interrupts (but which would only be recognized when
the state scheduler gets control), and with possibly some action going on
in interrupts. the rest is creativity and understanding of the architecture
with its features/limitations... :)
