串口通讯的使用，有关手机来电显示的问题，很有参考价值

这个是串口通信的，基于停止等待协议编写源程序，欢迎指教-this serial communication is based, stop source for the preparation of the agreement, welcomed the exhibitions

两机串口通信 可以传送各种文件，包括二进制文件 可达RS-232最大速度-two serial port communications can be transmitted various documents, including binary files up to RS-232 maximum speed

PIC模拟异步串行通讯UART。用TMR0实现定时查询。任何带中断的PIC上都可以实现。可用此法扩展多个串口。-PIC simulation asynchronous serial communications UART. Timing TMR0 with inquiries. Any interruption with the PIC are to be attained. This method can be extended serial number.

上传个考勤系统,希望别人也能用.该代码只能算初级的东东,软件代码复用性不高,重复代码比较多.唯一感觉有点取鉴的可能就是端口和dll的连接,还有线程的使用,本想改一改,但是手头没有考勤机了,对应考勤机是890C的.-From a performance appraisal system, I hope others can use. The code can only count the primary Dongdong, software, code reusability is not high, repeat the code more. The only feeling a little check Kam is probably dll ports and connections, There are threads to use, simply wanted to, but do not have attendance machine, and the corresponding attendance machine is the 890C.

通过rs232，发送一条消息到另一端，可以打开端口，检查打开后才输入消息。

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.

一个串口通信的软件，需要spcomm组件，请注意-a serial communication software, the need spcomm components, please note
