摘要
此设计采用MSP430单片机对步进电机进行控制,通过I/O口输出的时序方波作为步进电机的控制信号,信号经过芯片ULN2003驱动步进电机;同时,用4个按键来对电机的状态进行控制,并用数码管动态显示电机的转速。系统设计包括硬件设计和软件设计。系统软件采用在IAR for MSP430软件环境下编辑的C语言。
In this design,MSP430 is used to control the stepping motor,the timing square wave through the I/O port output is taken as a control signal of the stepping motor,the signal drives the stepping motor through the ULN2003 chip.At the same time,four buttons are used to control the status of the motor,and a digital control is used to display dynamically motor speed.The system design consists of hardware and software design.Software uses C language in the software environment to edit IAR for MSP430.
