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.

这是介绍嵌入式系统Bootloader的一篇文章，从网上下的，写的不错。vivi是嵌入式Linux的启动代码。-This is the introduction of the embedded system Bootloader of an article from the Internet and write well. Anger is embedded Linux boot code.

采用STM32F103C8T6，完成在DFU方式下，程序下载，代码用keil开发，简洁容易移植。主要实现主机通过usb接口对从机usb配件及设备进行在线编程，从而用来实现远程升级应用，也可通过linux系统进行移植，使系统功能更加完善，更加便于用户体验和使用。
