 Please review my design.... Hey, I designed this schematic diagram for a RS-232, PIC16F628 microcontroller and a stepper motor. The aim of the design is to control the stepper motor from the serial port through a microcontroller interface. I am not sure about what should be connected to the oscilattor inputs of the microcontroller if any. plz review my hole design... I know that I have asked many questions so far on this subject but excuse me Im really busy working on a c# code for the same project and do really need ur help when it comes to the microcontroller phase of the project at which it's my 1st working project. Please find my design attached. | |
