USB的驱动程序源码，主要实现与arm开发板的USB通讯，保证数据正确的传输。-The source code for USB driver,mainly used for communicating with arm developing board to guarantee transmitting data correctly

这个一个与具体设备无关的特殊设备的驱动程序，实际中，还可以涉及到很多内容，如ioctl、I/O端口等，此方面，我进在研究学习中！-This has nothing to do with a special device-specific device driver, in practice, but also involves a lot of content, such as the ioctl, I/O ports and so on, this connection, I entered in the study of learning!

函数发生器是一种在科研和生产中经常用到的基本波形产生器，集成函数 波形发生器一般都采用ICL8038或5G8038，而它们只能产生300kHz以下的中低频正弦波、矩形波和三角波，且频率与占空比不能单独调节，从而给使用带来很大不便。本文介绍由LM324和稳压管组成的低频函数波形发生器，该电路能够产生正弦波、方波和三角波信号，频率能以10Hz的间隔在20Hz～20KHz范围内调整。-Function Generator is a scientific research and production often use the basic waveform generator, integrated function waveform generator usually used ICL8038 or 5G8038, and they only have a 300kHz following the low-frequency sine wave, square wave and triangular wave, and frequency and duty cycle alone is not regulated, so as to enable using bring a lot of inconvenience. This paper introduces the LM324 voltage regulator tubes, and the low-frequency waveform generator function, the circuit can produce sine, square and triangular wave signal frequencies of 10Hz to 20Hz at intervals within ~ 20KHz adjustment.
