【Abstract】 Simple circuit structure,efficient control strategy,and reliable control are the common goals of control of all stepper motors.Fortunately,Cypress introduced the new PSoC3 in 2009,and simultaneously launched an integrated development environment dedicated to PSoC3-PSoC Creator,and this brings a new pattern to stepper motor control and provides the maximum possibility for its implementation.This article describes a stepper motor control technology based on PSoC3 chip.The design used two-phase bipolar control technology with simple external circuit which will save time and money.The stepper motor to be designed has many control functions: adjustable micro-step pace,adjustable motor speed,adjustable steering and so on.Finally,under the various subdivision paces of a prototype the voltage of MOS pin has been tested,and good waveform and data have been obtained.更多还原
