Hi to all!
Thanks for the answers to my previous posting. I need to know if anyone has a simple circuit for controlling a stepper motor with port1 of an 8052. I know that I should drive two coils at a time, but I don´t know the exact sequence.Also I don´t know where can I get a circuit that accepts TTL levels as inputs and drives a motor directly. Any clue will be appreciated. Sorry for my simple questions but I´m a microcontrollers newbie!.
