YAFFS A NAND-flash filesystem的介绍文件，读后会对YAFFS有较好的了解--You will have a better understanding of YAFFS after reading this article.

Part IV In part II we discussed the conversion of binary numbers into decimal digits. It is sometimes useful to build circuits that use this method of representing decimal numbers, in which each decimal digit is represented using four bits. This scheme is known as the binary coded decimal (BCD) representation. As an example, the decimal value 59 is encoded in BCD form as 0101 1001. You are to design a circuit that adds two BCD digits. The inputs to the circuit are BCD numbers A and B, plus a carry-in, cin. The output should be a two-digit BCD sum S1S0. Note that the largest sum that needs to be handled by this circuit is S

在其他网站上引述了一篇代码，虽然将自己没有完全看懂，但对想学lwip协议的童鞋讲还是不错的借鉴。也是在查阅lwip相关文档时，发现热心人上传的，此处借用啦！！！！！！！！！！！！！！！！！！！！！！！！！

使用STC15W4K系列MCU发出带死区的PWM波，占空比可调，可用于驱动半桥电路，BUCk，BOOST带同步整流的驱动。使用本代码前，请到STC官网下载STC15W4K系列的头文件，这里不给出。使用函数set_pwm()可设置占空比，使用前要先初始化init_pwm().在初始化函数里涉及到PWM引脚，PWM周期，初始电位，是否在二分之一duty处触发ADC，初始占空比设置，使用时可以参照数据手册按需求修改，这里只是一个实际的应用例程，希望有所帮助。
