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。

Lakey这是一个免费的CW练习/收/发软件，供大家共同学习研究，有需要源码的朋友可以给我发邮件或加为MSN索取。在未来，我会不断更新其功能和修正错误。之前计划2006年底前拿出的正式版本，由于个人工作和精力等原因，不得已推迟。今天发布的版本，增加了对Koch练习法的支持。但仍然是一个BETA版。 本软件的目标是设计成一个使用简便，能够尽量利用一般PC本身具有的硬件功能和性能（主要指CPU的运算和声卡的音频捕捉/播放能力），实现不用另接特殊外围接口电路，不用改/加装电键等，即可让PC具有摩尔斯电码（Morse Code）的收发能力软件。未来可逐渐通过对PC硬件性能的挖掘，实现对音频信号进行分析、过滤、处理。 这是第一个非正式发行版本，因此很多功能与设计目标还有很大差距。希望大家多提意见！ -Lakey This is a free CW practice/admission/software for the common study. need the source code to my friends or by mail from MSN Canada. In the future, I will constantly update its function and correct mistakes. Before the end of 2006 before the plan put forward by the official version, due to personal work and energy reasons, a last resort postponed. The version released today, an increase of Koch practicing law for the support. But this is still a BETA version. The software is designed to target an easy to use, to make the best use of the general PC hardware itself is functional and performance (mainly referring to the CPU arith
