This tutorial helped me realize I can use an ADC instead of a comparator. BEMF calculations will lag by one step in the commutation sequence but since the ADC returns the peak and minimum current of a given phase all I have to do is divide the clocks by two.

Great explaination

[@dogukantombul1045]

so which one has much efficiency than other one

[@dmitrym3757]

How do I detect a zero-crossing of Back EMF, when my ADC can only operate from 0 to 3.3 V. Should I offset it with an OpAmp, or just hook up a big enough resistor and hope for the best?

How to know w(speed) value for calculating bemf ?

[@awaitingthetrumpetcall4529]

This video just helped me realize that I can see the current swings with an ADC. I always thought I needed a comparator to see the zero cross. With an ADC all I have to do is count the clocks between the maximum and the minimum current swings and divide by two.
