本文介绍了一种采用AVR 高性能单片机Atmega128 与串行通信相结合的步进电机控制系统。该系统主要由上位机（PC 机）、下位机（单片机）及步进电机三部分组成，上下位机通过串*互数据。最终实现了由PC 机直接控制步进电机。调试结果表明， 设计的控制电路和程序简单、实用，且具有便捷的人机交互界面。-This article describes the combination of a high performance AVR microcontroller Atmega128 wit

The MSP430 micros have JTAG interface that allows access to the internal bus of the processor to locate breakpoints (breakpoints), analyze the values ​ ​ of the variables in memory and run the program instruction by instruction. This interf
