一个gps通讯接口程序可及时更新计算机时间

多串口调试，可以在同一个机子上连接，也可以用RS-232连接到两个机子上测试串口通讯，-Multiport Serial debugging, you can connect with a machine, can also use RS-232 connected to the two machine test serial communications,

采用C语言,软件模拟硬件UART端口,基于PIC系列处理器实现.-Using C language software simulation of hardware UART ports, based on the PIC family of processors to achieve.

SPI串行总线的AT45DB081的C语言控制源程序-the c progranm code of AT45DB081 with SPI serial bus

串口通信例程，内含串口类，一个老外写的，我修正了一个bug：在接收数据流未完成前退出程序会导致进程驻留在内存-Serial communication routines, containing serial port class, written by a foreigner, I fixed a bug: the receiving data stream does not quit the program before the completion of the process will lead to reside in memory

本程序是i2c总线读写一个字节的程序。在写过程序中，不一定非要检测i2c的应答位，可以直接延时过去就行，但是在读过程中必须给应答信号，读完发停止位，一定确认所发的信号都发上了。否则在连续地址读的过程中可能不会出错，但是在随机度过程中就会出错，我的程序就是在给停止信号时没有给上，24cxx一直在输出数据，结果读出错。找着问题后我的程序只加入了一条命令便完全正常。-i2c bus read and write a byte procedures. The written procedure, not necessarily require the detection i2c-response, and can directly past trip delay, but the process must be read to the response signal, stopped at reading, we recognize the signals are on the fat. Otherwise, the address read for the course could not go wrong, but the randomness of the process would be a mistake, I was in the process to stop for no signal, 24cxx in output data, read errors. I discovered the problem after the procedure just joined the order of a completely normal.

好用的串口调试工具，可自定义波特率，这可是一般的没有的-useful debugging tool available from the definition baud rate, but not the general

用从c++编写的串口通信程序，内有详细的了解并设置串口参数的源码，并含通信原理-prepared from the use of serial communication program, with detailed understanding of serial port parameters and set up the source code, and communication with Principle
