HI all,
Im new to design and development of uC based solution. Im trying to control speed and position of 3 Phase AC Induction motor using ATMega1284P. I have successfully interfaced Rotary Encoder for judging position of rotor.
My aim is to send commands using serial for degrees to move in a particular direction with a certain speed and stop rotor on reaching the desired position.
Any help in this regards particularly a reference project will be highly appreciated.

Although not Atmega based, there is app notes on the Picmicro site and also the Power IC manuf such as International Rectifier, Freescale etc.
