51单片机开发步进电机源代码及报告解释说明(a progress of 51MCU introduction)

STM32F1与FPGA通过SPI进行通信，我上传的是32部分的程序，已经通过串口测试成功。此程序可拓展为和单片机，DSP通过SPI进行通信(STM32F1 and FPGA communication through the SPI, I uploaded the 32 part of the procedure has been successfully tested through the serial port. This program can be extended to and single-chip, DSP communication through the SPI)

AD9850 AD 9851 并行 串行控制程序 很好的资料 以前自己花钱买的啊 (AD9850 AD 9851 serial parallel data control procedures well before the own money ah)

正弦余弦三角曲线的绘制,用了ListCtrl,Slider等控件,供初学者学习参考.(cosine 1.30 sine curve mapping, spent ListCtrl, Slider, etc. Controls for beginners learning reference.)

打孔机主要用于在制造印刷线路板流程中的打孔作业。本问题旨在提高某类打孔机的生产效能。 打孔机的生产效能主要取决于以下几方面：（1）单个过孔的钻孔作业时间，这是由生(this is a new suan fa ofaa)

基于51单片机的32和弦音乐盒程序，有曲目切换，音量调节，播放时间，步进电机驱动，流水灯等功能，是普通音乐的升级版本，且代码清晰，注释完整，结构合理。(Based on 51 single-chip 32 polyphonic music box procedures, switch tracks, adjust volume, play time, stepper motor drive, water lights and other functions, is an upgraded version of the ordinary music and clear code, comments, integrity, reasonable structure.)

说明：  独居老人监控系统 使用80c51f020编程 具体的使用方法和接口，里面有(Elderly people living alone monitoring system using 80c51f020 programming methods and the use of specific interfaces, which has)

For this project you need a 3.7v power supply that prepared by LM317 regulator. So you need MAX232 for connect uart to pc .my AVR chip project is Mega8 that you can program on any Avr chip have 2kbyte rom. In bascom spi hardware don’t work correct, so I have to software spi ,but the software spi configure have low speed into hardware spi.
