用8098单片机实现步进机细分控制接口

Controlling system for the fractional angle operation of stepping motor by 8098 microprocessor

利用8098单片机独特的硬件资源，设计了一个新的步进机细分控制接口电路，输出的斩波电压经调整后可降低绕组的电流波动，实现电流逐步平稳的升降，减少电磁噪声．

This paper develops the new peripheral system which is controled by microprocessor 8098,the system operates in a fractional angle way,the current waviness can be obviously decreased by using the method. The reaction of the system is smooth and rapid.
