一种基于C8051F单片机的直流无刷电机转速控制系统

单片机程序采用C51完成，部分源程序如下：

系统时钟初始化，采用18.432MHZ外部晶振

IO口初始化-C8051F MCU based on brushless DC motor speed control system for single-chip process using C51 completed and some of the source code is as follows: initialize the system clock, using an external crystal 18.432MHZ I initialize IO
