i want to use a similiar circuit for zero crossing as in the atmel apllication.. here i attach a schematic which i want to use ? i also want to add an ac isolator maybe PC814. how do i incorporate it into this schematic ? wat should the value of Ry and Rx be ??

i am using zero crossing to determine the delay in the mcu fter which i trigger the triac
any help will be appreciated
thanks
