一个很好的水文监测系统 vb 串口

可以自己修改及优化的串口程序。你可以自己改作其他串口通讯程序。-can adapt and optimize their Serial procedures. You can, for other serial communication procedure.

SPI读写，通过ＲＳ２３２协议传输！弹片机读写！-err

采用verilog编写的串口通信程序，采用了状态机设计！程序简单，消耗资源少-Serial communication written by verilog hdl. It is designed with FSM. The program is simple,and consume resource is few.

从串口读取数据，有两种方法， 1、每接收一个EV_RXCHAR,就用ReadFile读一次，这样我觉得太恐怖了。 2、接收到一个EV_RXCHAR后，等一定数据量的CPU周期(GetTickCount),再一次性读取缓冲区里的数据。这样做，一般情况下不会有问题，但是，如果数据很多，过了“一定数据量的CPU周期”，还没收完数据怎么办？就会少读数据了。 我用三个线程序来完成串口数据的-read data from the serial port, there are two methods, one, each receiving a EV_RXCHAR, on the ReadFile read, I think this vote. 2, received a EV_RXCHAR after a certain volume of data, such as CPU cycles (GetTickCount), and the one-time reader, the data buffer. To do so, under normal circumstances there is no problem, but if many of the data, and after a "certain amount of data the CPU cycles," also confiscated End Data how do? Few will read the data. I used three lines to complete serial data
