The purpose of this document is to present how to use the Timer for the generation of a PWM signal tunable in frequency and duty cycle. As an application example, this document is based on a basic “music” synthesizer through an external buzzer. Example code is also available in the it.-The purpose of this document is to present how to use the Timer for the generation of a PWM signal tunable in frequency and duty cycle.

数字图像放大缩小及旋转计算组间方差和组内方差的时候调用了一个函数专门求阈值，可能这里的计算还是有一点问题。而且在我的函数里，要256次调用这个函数，又因为计算机是按字节处理数据的，因此写图像数据的时候要用每8个写到一个数组中，然后通过计算得到字节类型的值，这些都使得我的算法效率比较低，最后一个问题，我觉得如果使用位运算会快一些，但是前面的问题还没有想到比较好的解决方法。-Digital Image zoom and rotation calculation of variances and group between the two groups when the variance of a function call seeking specific threshold, the calculation may be here, or there was a problem. And in my function, it is necessary 256 calls to this function, and also because the computer is processing data in bytes, and therefore the time to write image data to use for every 8 write an array, and then calculated byte type values, which are made to my algorithm" s efficiency is relatively low, the last issue, I think that if you use bit computing will be faster, but the previous issues have not yet thought of a better solution.
