用PWM产生锯齿波，应使PWM寄存器中的值线性增加，那么在PWM输出端将得到宽度线性增加的脉冲波，经滤波后，便可得到锯齿波。-have used PWM ramp, it should PWM register with the value of linear increase, then the PWM output will be increased linearly width of the pulse wave, filter, which will be ramp.

我们可以采用两种编程方法,一种是自己编写控制各种寄存器代码进行数据的采集和输出,另外一种就是利用他封装的DLL的方法访问相应的函数进行完成.为了节省时间提高开发效率,当然使用第二种方法了-we can use two programming methods, one is prepared to control their various register code data collection and output and the other is to take advantage of his package DLL visit to the corresponding function completed. In order to save time to improve the efficiency, of course, use the second method
