yep i am thinking about that way of going , although for the 4 input its is sort of working using just the timer as the base ref at the moment will see if it see all it should , but thinking pic with a alot of CCp might be worth a run as well , have some 16F1825 here which has few CCP in it see if that works as well.

still big learn curve to make this work at all

Cheers
