以前做的一个仿真，关于空间矢量控制的，看看能不能给有需要的人！(Ago to do a simulation, on the space vector control, can look to those in need!)

由于超声波指向性强，能量消耗缓慢，在介质中传播的距离较远，因而超声波经常用于距离的测量，如测距仪和物位测量仪等都可以通过超声波来实现。利用超声波检测往往比较迅速、方便、计算简单、易于做到实时控制，并且在测量精度方面能达到工业实用的要求，因此在移动机器人研制上也得到了广泛的应用。(Because of its strong directivity, slow energy consumption and long propagation distance in the medium, ultrasound is often used for distance measurement, such as range finder and level gauge, which can be achieved by ultrasound. Ultrasound detection is often fast, convenient, simple in calculation, easy to achieve real-time control, and can meet the requirements of industrial application in measurement accuracy, so it has been widely used in the development of mobile robots.)

ARM Cortex-A8 裸板，定时器4 和定时器0的测试程序(ARM Cortex-A8 bare boards, Timer 4 and Timer 0 testing procedures)

基于IAR开发环境，野火GPIO 配置文件，包含C和H文件(Based on the IAR development environment, wildfire GPIO configuration file, including C and H files)

old gpio interface to other kernel modules don t use in new code, will go away in 2.7 have a look at bttv-gpio.c instead.

说明：  STM32F407驱动SPI屏幕，采用的是模拟SPI(STM32F407 drives SPI screen, using simulated SPI)

这里面是一些我们平时上实验课做的一些单片机的基本实验，应该很有帮助(That there is something we usually do some of the experimental course on the basic experimental SCM should be helpful)

说明：  基于51单片机的DHT11温湿度报警模块，附带源码和仿真。(DHT11 temperature and humidity alarm module based on 51 MCU, with source code and simulation.)
