ABSTRACT
Along with the puter widespread application, the monolithic integrated circuit application also thoroughly arrived social domain each aspect, For this anthology graduation project topic is: Based on the P89C668 Single chip puter. Stepping Motor movement control system research and development, the P89C668 Single chip puter belongs to Philips the enhancement 8051 series. This design is controls a Stepping Motor revolution using Single chip puter, through the key scanning, the procedure control realizes Stepping Motor stops, the reverse, adds the state of motion which, decelerates, This design applies the development kit is Proter DXP2004 andμVision2, this system carries on the control using the assembly language.
In the main text first simply described the topic background, the function which the development environment and needs plete; Then introduced the system plan design, including the hardware shaping and its the work process which this graduation project applies, this part for system hardware design, attaches the corresponding circuit diagram, and has produced the system hardware design assembly drawing. Also simply described the enhancement 8051 Single chip puter electric circuit connections hardware debugging in the main text.
