Stepper Motor Controller: Overview Details Name: steppermotordrive Created: 23-Apr-2004 16:39:52 Updated: 17-Dec-2005 00:33:22 CVS: browse Other project properties Category :: Communication controller Language :: VHDL License :: GPL Phaze :: FPGA proven Development status :: Production/Stable Project maintainers Steve Franks Statistics view Description A very simple project for controlling any standard 4 or 6 wire stepper motor. Only difference between 4 and 6 wire mode is the MOSFET driver circuit (6 wire steppers are considerably simpler...) Features Simple VHDL for beginners; well documented NPL project file for immediate evaluation in Xilinx ISE/Webpack tools Quickly get a stepper motor running for testing or prototyping Questions/Comments: http://www.franks-development.com Project Contents StepperMotor.npl, project file for Xilinx ISE/Webpack StepperMotorDrive.vhd, source code StepperMotorDrive.ucf, constraints file for pin assignments, etc. StepperMotorWiring.bmp, schematic for connecting motors. Given MOSFETS with sufficiently low Vgs-on, can be driven directly from logic.
