OV7660 YUV源代码，已经验证不会有问题

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

目录串口通信高级编程提供了一个能够进行串口通信的类，能够方便地进行各种数据通信。-Directory serial communication provides a high-level programming to carry out the type of serial communication, the ability to easily conduct various kinds of data communication.

eVC下操作串口提取GPS有效数据2，把文件名的后缀.rar去掉即可，不要解压缩。-operate under effective Serial GPS data from two, the file name suffix. Rar be removed, not decompress.

串口读取短信猫中的短信内容和利用串口发送短信的小软件。比较初级，但是想利用串口通讯的可以参考。-serial cat read the SMS messaging content and the use of serial send a message to a PC. Comparison of primary, but want to use serial communication reference.

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.

IC卡考勤系统源代码,动态连接库中函数说明,源程序中有相关的使用说明.-IC card attendance system source code, dynamic link library functions show that the source is related to the usage instructions.

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.
