In general, the libraries that tie directly into AVR timers are "difficult"= , not just because of cpu-dependent register names and configurations, but = because the pic32 timers are relatively significantly different than AVR ti= mers. Alas, this is a popular thing to do, since it's about as close to "m= ultitasking" as small microcontrollers get...
