485转以太网接口

SIM800A驱动代码，包含GPRS数据通信，短信息收发和打电话的代码及其详细说明。做到串口透传命令让GPRS通信收发抑或电话拨打接听挂接等内容。

利用前推回代法计算ieee33节点的潮流，计算的速度快，精度高容易收敛。(The forward and backward substitution method is used to calculate the power flow of IEEE 33 nodes. The calculation speed is fast, the accuracy is high and the convergence is easy.)

是一个em78p153s的简单DEMO，用于输出(it is a simple em78p153s demo to applicate output)

该程序是一个仰邦LED卡的Demo,主要是有连接控制卡、通过控制卡向LED发送文字、通过控制卡展示表格，注意该程序使用的是LedDynamicArea.dll动态链接库实现的，如果你有什么新的想法，可以在https://xian689.com沟通

This is a very minimalist, but clean implementation of MP3. It can be used as a starting point for an encoder.

说明：  描述G729A标准，通过该文档的学习，能了解G729A原理。(Description of G729A Standard.)

说明：  基于MSP430F5438A的AD9854驱动，AD9854的DDS核具有48位的频率分辨率（在300M系统时钟下，频率分辨率可达1uHZ）。输出17位相位截断保证了良好的无杂散动态范围指标。AD9854允许输出的信号频率高达150MHZ(Based on the AD9854 driver of MSP430F5438A, the DDS core of AD9854 has a frequency resolution of 48 bits (up to uHZ at 300 M system clock). Output 17-bit phase truncation ensures a good dynamic range index without spurious. AD9854 permits up to 150 MHZ of output signal frequency)

本程序是c#编写关于幼儿园出勤的划卡系统，有感兴趣的朋友可以参考一下。(This procedure is a c# delimit of nursery school attendance card system, inductive interested friends can reference it.)

该编程使用VC++编写代码,该编程主要作用便是将灰度图像的各灰度值统计出来,以方便对该灰度图像的了解 (The programming code using VC++ The main role is to be programmed for each grayscale image gray value statistics out to facilitate the understanding of the gray image)

VLD支持排查特定线程的泄漏,所有线程的泄漏,在特定的阶段启用泄漏检查,安装完成后,即可启用内存泄漏检测了(VLD supports troubleshooting leaks from specific threads, leaks from all threads, and leak checking is enabled at a specific stage, and memory leak detection is enabled when the installation is complete)
