基于MSP430G2553的频率计数计的程序编写，已经过测试，程序无误可以完整运行。(Based on the frequency count MSP430G2553 meter programming, has been tested, the program can complete run correctly.)

通过WM_DEVICECHANGE来检测u盘的传播者源代码(through WM_DEVICECHANGE to detect u site promoters source code)

SIM800C升级工具,二次开发工具，省成本的特别好用用的方案(SIM800C upgrade tool)

时钟的应用源代码，可以让初次设计有关定时操作的人员借鉴。 (Clock application source code, allowing designers about the timing of the initial operation of reference.)

For this project you need a 3.7v power supply that prepared by LM317 regulator. So you need MAX232 for connect uart to pc .my AVR chip project is Mega8 that you can program on any Avr chip have 2kbyte rom. In bascom spi hardware don’t work correct, so I have to software spi ,but the software spi configure have low speed into hardware spi.
