说明：  两脉冲频率平均值计算 两脉冲频率平均值计算 两脉冲频率平均值计算(Two pulse frequency average of the two pulse frequency average of two average pulse frequency)

说明：  四方的通信管理机程序，绝对的超值，很多规约的处理，101 103 103 104 CDT DNP SC1801 CSC2000等，千万别走漏风声啊，(sifang processs protel control center )

AD转换资料，超全大量AD采集电压以及采集电流的方法！(AD conversion data, a large number of ultra-wide voltage and collected current AD acquisition method!)

说明：  本系统以单片机AT89C51为主体,由芯片插座、独立按键、74HC573驱动8位数码管显示、5V直流电源控制模块等组成。根据数字集成芯片的引脚特性以及集成芯片的真值表编写检测程序。该系统能完成14脚以内常用TTL74系列数字集成芯片的功能测试。(This system is the main body of the single-chip microcomputer AT89C51, the chip socket, independent buttons, 74HC573 Driver 8 digital control, 5V DC power control module and so on. According to the characteristics of the digital chip and the chip s true value, the program is written in the chip.. The system can complete the functional test of the TTL74 series digital IC chip in 14 feet.)

Simple Open Source EtherCAT Slave ==== SOES (Simple OpenSource EtherCAT Slave Stack) is an opensource slave stack that is very easy to use and provides a small footprint. It is a good alternative to more complex stacks on the market. Overview SOES is an EtherCAT slave stack written in c. Its purpose is to learn and to use. All users are invited to study the source to get an understanding how an EtherCAT slave functions. Features as of 1.0.0: - Address offset based HAL for easy ESC read/write access via any interface - Mailbox with data link layer - CoE - Object dictionary - SDO read and write for all sizes including segmented transfers - Easy portable C-code suited for embedded applications - Fixed PDO mapping - FoE with bootstrap template - Support for Little and Big endian targets. - Polling for interrupts
