基于s3C2410的源代码 在linux操作系统下实现

提供的程序是供四相步进电机使用。本实验使用的步进电机用直流+12V电压，电机线圈由A、B、C、D四相组成。 2. 驱动方式为四相单四拍方式,各线圈通电顺序如下表。表中首先向A相线圈输入驱动电流，接着向B，C，D线圈通电，最后又返回到A相线圈驱动，按这种顺序轮流切换，电机轴按顺时针方向旋转。若通电顺序相反，则电机轴按逆时针方向旋转。-provide for the procedures of the four-phase stepper motor use. This experiment used the stepper motor 12V DC voltage electrical coils A, B, C, D phase. 2. Four-driven approach to making four single-phase, the coil electrifying sequence the following table. Table A first phase coil input drive current, then to B, C, D coil electricity and eventually return to the A-phase coil driven by the rotation order of this switch, the electrical axis by rotating clockwise direction. If electricity in reverse order, the motor shaft by the anti-clockwise rotation.

基于C8051F340的SD卡读写，移植了FATFS的文件系统。可以实现文件的读写。本人验证通过，可对有文件系统的SD进行读写。-Based on C8051F340" s SD card reader, transplant FATFS the file system. File read and write can be achieved. I verified by, a file system can read and write SD.

读写USB端口的VC程序，编译说明 ： 1. 安装DDK 2. 把DDK的inc路径填在头文件的包含路径中 3. 把DDK的lib路径填在库文件的包含路径中 4. 注释掉原代码中的HIDD_ATTRIBUTES结构 // 不知作者为什么要添加这个结构定义 5. 添加setupapi.lib 如果不想安装DDK，就去掉前两步，但需要拷贝相关的头文件和库文件到工程目录--A VC program reading/writing USB port. Compilationg steps: 1. install DDK. 2. include DDK s inc path in header file s searching path. 3. include DDK s lib path in the library s search path. 4. comment out HIDD_ATTRIBUTES structure in the source file. 5. add setupapi.lib. If you don t want to install DDK, you could omit the first 2 steps, but you need to copy corresponding header files and library files.
