HİGH SPEED COUNTER

Hi everybody,

I want to detect 60 dry contact in a second from pic 16f84 it seems possible.But hoe csn simulate in proteus. What should i use for dry contact

[pickit2]

if by dry you mean relay/switch contacts, then you could make a part by pulse generater mode @ 60hz into driver and a relay, crude but will work.

Need clarification here. 

Are the pulses FROM the PIC, or headed TO the PIC?

Do we want to be sure they are 60 per second or ?

you should have to connect the resistor from 'NO' contact to Ground in order to make the real clock of high and low pulses, by reading the schematic i have observed that CLK pin receives only high pulse not low pulse, the state is not chaning from high to low and then low to high.
