说明：  基于51单片机的超声波测距模块使用，使用HC-SR04模块，定时器测量回波长度(Ultrasound Ranging Module Based on 51 Single Chip Microcomputer)

说明：  可以实现陀螺仪角度检测以及角度时间在oled上的完美显示(The gyroscope angle detection and the perfect display of angle time on OLED can be realized.)

一个多通道ADC转换DMA传输数据。程序是选择的通道0和通道1，各采集50次，然后滤波取其平均值，并发送到串口显示采样的电压值。(A multi-channel ADC conversion DMA transfer data. Program is selected channels 0 and 1, each collecting 50 times, then filtering the mean value, and sent to the serial display sampled voltage value.)

成都无线龙实验箱开发板实验，用ARM控制GPRS打电话实验 (Chengdu wireless dragon experimental box development board test, experiment with ARM control GPRS phone)

mmc基本仿真,用于mmc环流抑制，包含了三相不平衡负序分量的处理(Basic simulation of mmc)

No reason to add a space last if the money symbol do not have to be display.

这是一个51单片机的菜单设计例程，使用时要做一些修改(This is a menu of 51 single-chip design examples, used to do some modifications)

说明：  用lpc213x IO口模拟spi对倾角传感器SCA103进行读取 这个程序读取的是温度 读取角度的自己稍微改下就好(Lpc213x IO port with analog spi 字典 )

用于全桥逆变电路的移相软启控制程序，周期和启动时间均可调节。(Phase-shifting soft-start control program for full-bridge inverters has adjustable cycle and start-up time.)
