Control stepping motor via USB interface

 


This is an example that demonstration how to control some devices via USB interface.The PC software program with delphi. Feature: - CPU PIC18F4550 with full speed USB interface at 48MHz. - USB 2.0 compliance - Use on-chip USB driver - Control 1 stepping motor. - MPLAB C18 for firmware at USB devices side. - Delphi 6 for PC Host software. USB devices side Figure 1. is the schematic for this example.PIC18F4550 is the main devices that communicate with PC and control stepping motor. The power supply came from +5V Vbus for circuit except +Vmotor which must use external power supply that depend on stepping motor requires. If you add more components into circuit that drawn total current more than 250mA you should be use +5V external power supply instead Vbus.Becuase Vbus can supplies current not more than 250mA and don't forgot to disconnect Vbus out of circuit.
