根据太阳电池量子效率曲线计算光短路电流密度(calculate the short current density according to the quantum efficiency curve of solar cell)

STM32单片机，采用数字相关法测量两路波的相位差，内含工程，进行了模拟数据测试通过，稍微修改即可使用，并附上了理论文档。(STM32 microcontroller, using digital Correlation Method for Measuring the phase difference between two waves, including engineering, tested by simulated data, you can use slightly modified, with a theoretical document.)

说明：  基于MSP430F5438A的AD9854驱动，AD9854的DDS核具有48位的频率分辨率（在300M系统时钟下，频率分辨率可达1uHZ）。输出17位相位截断保证了良好的无杂散动态范围指标。AD9854允许输出的信号频率高达150MHZ(Based on the AD9854 driver of MSP430F5438A, the DDS core of AD9854 has a frequency resolution of 48 bits (up to uHZ at 300 M system clock). Output 17-bit phase truncation ensures a good dynamic range index without spurious. AD9854 permits up to 150 MHZ of output signal frequency)

STM32系列单片机USB声卡实验，希望为广大初学者带来帮助。(STM32 series of MCU USB sound card experiment, hope for the majority of beginners to help.)

STM32的一些实例程序，能够很好的移植(STM32 some examples of programs can be a good transplant)

一调试好了，放心使用吧，很好的，保证你会满意的。(A debugging good, feel free to use, very good, guarantee that you will be satisfied.)

该程序为初学者学习单片机时使用的60S倒计时程序，可将开程序用在proteus软件上进行仿真，我试过可行的~(The program for beginners to learn the use of single-chip microcomputer of the 60S countdown procedures, can be used in open procedures proteus simulation software, I tried to possible ~)

ev1527解码方式非常好用,请大家参考一下，给个意见(ev1527 decoding is very easy to use, please refer to different views)

用CC1110来控制的一个贪吃蛇的小游戏，按键来控制(CC1110 to control one Snake game, key to control)

c8051f020的24c02程序，经测试验证可以使用。(c8051f020 of 24c02 procedures, verified by testing can be used.)
