hello,
for a alternator regulator using 12f683 pwm, i want to smooth a/d readings by taking 3 readings and discard the high and low reading to make next pwm calc. I'm trying to keep math calculations from slowing down process too much. any fast way to check 3 readings and discard high and low reading?

also working on a self tuning PID. seems like the micro and program could tune itself to simply reduce/increase P,I or D to stop or set overshoot .am i missing too many brain cells?
