Hi!
    I am working on 3 phase induction motor project and i have also read microchip AN889 for this task but the code that microchip provides is in assembly and my assembly is not so good so that's why i have face problem in understanding the code. Can anyone do this project of 3 phase induction motor control on "Proton" then please share it with me on the forum.
 Also in AN889 the timer1 reload value formula is
Timer1 Reload Value = FFFFh – 2 x((FOSC/4)/Sine Samples per Cycle x Timer1 Prescaler x Value of AN1)

In the above formula the Timer1 Prescalar is set to '1:8' so what i have to put in Timer1 Prescalar '8' or '1/8'
Please help me in solving this problem and share the project if any body have done it or working on it.

Any kind of help will be highly appreciated.
