how 44B0 development board ARMSYS on NFS

应用背景通过dma控制来读取ad信号，在很多传感器应用方面都能用到，比如压力传感器读取，温度读取等等而且用起来也十分方便。希望能帮助大家。关键技术读取ad信号，dma读取，嵌入式开发，不是位操作，看起来通俗易懂，而且开发容易，还包括一些其他信号的读取，如超声波，气压计，加速度计等等。

STM32的PWM详细例程，能够使用的，下载完了要给点回复哦！-STM32 detailed the PWM routines, can use to download the end-point to give back Oh!

s3c44b0X,LCD测试程序，分别进行黑白、4级灰度、16级灰度和256色伪彩屏测试-s3c44b0X, LCD testing procedures were black and white, gray 4, 16 and 256 gray pseudo-color screen test
