PWM输出源程序,飞思卡尔单片机实现，以SR12为例

程序描述：使用Cypress的Cy7C68013A芯片进行设计，控制外部LED数码管的显示。程序包括USB固件程序以及主机程序。 安装：把源码拷贝到硬盘特定目录下，使用Keil C编译器和Visual C++ 6.0运行即可。 注意：可以首先使用Cypress的调试工具进行固件程序的调试，以确保固件程序的正确性。 -Description: Using Cypress

LCD1602的显示程序，用的是S51单片机，已通过调试。-LCD1602 display program, using a S51 MCU has passed debugging.

keil c51下基于软件模拟I2C总线的Dll动态连接库。下载后将其烤到keilC51in下即可。-keil c51 simulates I2C based on software the main line the Dll dynamic connection storehouse. After downloading roasts it to keilC51in under then.

三星公司的一款1602vfd显示屏，它的特点是便宜，目的是为了取代相应的液晶显示屏。由于vfd的亮度的天独厚，温度适应性宽，所以在工业环境中的重要性毋庸置疑，我给美国老板开发了这个四路温度显示。已经使用两年了。-Samsung 1602vfd a display, it is characterized by cheap, is designed to replace the corresponding LCD screen. Because the brightness of the day vfd independence thick, wide temperature adaptability, so in the industrial environment, the importance of doubt, I am the boss to the United States has developed this four-way temperature display. Has been used for two years.

采用12位MAX 197对外部信号采样。采用全周波傅立叶积分算法，对采样信号进行处理，对电力系统的电压有效值、功率等特征量进行实时在线监测；采用全数字测量法测量相位差；并采用自适应技术调整采样间隔，消除非同步采样对计算造成的误差，利用PIC18F458捕获功能实时监测电力系统频率波动，修订采样间隔。分析了各量的测量误差，均达到标准。并提供友好的人机交互界面。-used 12 MAX 197 pairs external signal sampling. Using Fourier-Cycle Integration Algorithm for the sampling signal processing, power systems to the RMS voltage, power characteristics of the volume in real-time on-line monitoring; All digital measuring method phase difference; Adaptive technology and the sampling interval, the elimination of non-synchronous sampling of the calculation error using PIC18F458 capture real-time monitoring of power system frequency fluctuations amended sampling interval. The analysis of the measurement error are up to standard. And to provide a friendly man-machine interface.
