Hello, first of all I would like to say "GREAT JOB" !
This controller is really nice and thought me a lot !

But still... where can I find an explanation to the circuit. For example what for transisotrs Q5 - Q8 are?
I'm trying to to put DAC between uC and transistors Q1-Q4, is there explained the method of microstepping? I know R18-R29 sets the microstep value, but if I wanted to use 8-bit DAC. Is it possible in this circuit?

thank you :)
George
