】　本文主要讨论了Modbus 通信协议的R TU 帧格式中常用的错误校验方法,即循环冗余校验法( CRC) 。 提出了Modbus 协议反转CRC 校验的方法,推导了反转CRC 校验快速计算表格,并用C 语言实现了基于快速查 表算法的循环冗余校验程序。-In this paper, we mainly discuss the Modbus communication protocol R TU frame format commonly used in error checking methods, namely, Cyclic Redundancy Check Code (CRC). Modbus protocol proposed inversion method CRC checksum, CRC checksum is derived fast computing inversion table, and C language to achieve a quick look-up table algorithm based on cyclic redundancy check procedure.

VC串口通讯资料-VC serial communications

关于Nrf905收发程序，很有用的程序，反对反对说地方是-Nrf905 transceiver on the procedure, useful procedures, opposition to oppose that is

这个程序用来说明单频离散序列的周期延拓和补零延拓会对频域的分辨率有什么影响，是我自己刚作出来的，就贡献了吧，请您审查通过-the procedure used to describe single-frequency cycle sequence of discrete Extension and Extension-zero frequency domain will have a resolution of any impact option is my own just to make the contribution on the right, please review by Thank you
