VB_Modbus-RTU

MODBUS RTU using Attiny44 from Atmel

利用vc++实现的一个直接序列扩频通信处理程序，包含了简单的测试数据。此程序很详尽。(Using vc++ to achieve a direct sequence spread spectrum communication processes, including a simple test data. This program is very detailed.)

自己整合的，可直接下载调试使用，傻瓜式文件一体包。(Integration of their own, can be downloaded directly debugging use, fool file integrated package.)

非均匀天线组阵SUMPLE权值信噪比及信号合成性能分析(Non-uniform antenna arraying SUMPLE weights SNR performance analysis and signal synthesis)

串口通过modbaus协议控制继电器，读取开关输入的PC上位机源程序(Serial control relay through modbaus agreement, read the PC host computer switch input source)

说明：  GPS串口通信程序，新建了一个数据库ACCESS，在显示当前GPS信息的同时可以存储以前记录过的信息，保存在数据库中，便于以后查阅。当前GPS信息包括：时间，经度，纬度，速度，真实航向以及磁偏移(GPS serial port communication program, a database of new ACCESS, show the current GPS information can be stored at the same time the information previously recorded, stored in a database for easy access later. The current GPS information including: time, longitude, latitude, speed, true course and magnetic offset)

VC开发的一款可以通过Access的增删改查进行存取记录的笔记本(VC Deve Note ,Could Sava your technology_note)

DXF轨迹图转G代码，有 直线，圆，圆弧，样条曲线，优化多段线，多段线。与下位机串口通讯！无法编译，是因为要先注册mscomm控件(DXF trajectories turn the G-code, line, circle, arc, spline curves to optimize the polyline, polyline. With lower serial communications! Not compile because the first registered mscomm controls)

modbus rtu 校验vb源码，对VB学习者很有帮助(modbus rtu checksum vb source code, useful for VB learner)
