This model is just testing an idea of MIMO, which IEEE802.11n will have. But I havo not seen the standard, I tried to make it with 11a. Actually this model would not work in real world, because the preambles were not designed to solve the MIMO feature. But this model may be useful to get some idea to start to design a PHY with MIMO. -This model is just an idea of testing MIMO. IEEE802.11n which will have. But I havo not seen the standard.

此程序需要从麦克风输入、 分析信号，然后将其发送的音频输出。可能配置各种参数，例如 FRAMES_PER_BUFFER、 SAMPLE_RATE、 NUM_CHANELS 等。

基于S3C2440 对 K9F1208 Nand Flash 的读写,取自uboot,对其进行了修改-S3C2440 based on K9F1208 Nand Flash reading and writing, from uboot, its modified

一个以AD9851做频率基准音频信号发生器，可以精确到0.01%。-AD9851 to do a baseline audio frequency signal generator can be accurate to 0.01%.

基于keil开发平台，在stm32板子上实现4x2键盘检测。程序完全正确能够完美实现功能。   部分代码摘录： void Task1(void *pdata) {   u8 key;   while(1)   {    key=KEY_Scan();    if(key==1)    {      digitalToggle(GPIOD,GPIO_Pin_7);  //D4亮     OSTimeDlyHMSM(0,0,1,0);    }    if(key==2)    {  digitalToggle(GPIOD,GPIO_Pin_6);  //D5亮    OSTimeDlyHMSM(0,0,1,0);    }    if(key==3)    {      digitalToggle(GPIOD,GPIO_Pin_5);  //D6亮    OSTimeDlyHMSM(0,0,1,0);    }   if(key==4)    {  &n
