thanks for the feedback
to bruce, you say the 18f2431 is specifically for frequency measurements. would that mean I would no longer need to attempt to code my program to measure the 0 points and then measure the frequency from the timings between the zero points? also you say it does two simultaneously? i have 3 phases from my analogue signal, which are split into 3 different signals, all of which i need to measure the frequency of and get an average. is this still possible with this pic?
and would using the 18f2431 be alot easier than using a schmitt trigger and just measuring the frequency of 3 square waves using interupts? would there be 3 places on the pic i could make these inputs aswell?
thanks
