由SPCE061A控制的74hc595的驱动程序,一般用于串转并-by SPCE061A 74hc595 control of the driver, generally for serial switch and

本程序用于用单片机控制步进电机的转动。用单片机的某一个引脚实现控制，如果引脚电平为高则实现正转，反之为反转。所用单片机为日立系列h83664十六位单片机。本代码使用c语言实现，开发环境为日立系列单片机专用开发环境-This procedure for the use of single-chip stepper motor rotation control. With a pin MCU control, if the pin level is higher then realize to the contrary, for the inversion. Used in single-chip for Hitachi Series 16 Singlechip h83664. This code uses the c language, development environment for the Hitachi series of single-chip dedicated development environment

在单片机上完全实现sd卡功能，对扇区操作都很详细。-In single-chip fully realized the sd card function, sector operations are detailed.
