Optical Encoder

[Userrr]

Help me with program of optical encoder were at 1-st out - logical 1
and at second out pulse freq.

I am not sure what your question is,but if you are trying to
get a count for an optical encoder input, you just have to make a simple state machine.
The inputs are either 0,0 or 0,1 or 1,0 or 1,1
so their are 4 states, only 1 bit will change at a time,
so as long as you know the last state, you know the new state
to go too, and you either increment your counter by 1
or you decrement your counter by 1

Or, you can buy the LS7083 chip from US digital to convert
your quadrature encoder into a up/dn pulse, which can feed into
one of the timer pins.
