实现公历与农历的转换一般采用查表法按日查表是速度最快的方法但51 单片机寻址能力有限不可能采用 按日查表的方法除按日查外我们可以通过按月查表和按年查表的方法...

由于输出的是方波，比较难听:-) 只能说是非常难听:-)为什么呢？只因为输出的是方波,包含了大量的奇次谐波。 你可以用双龙的"虚拟仪器"分别产生正弦波、三角波和方波听一下，正弦波感 觉就比较纯正，而方波则要多难听有多难听！-As the output is a square wave, more bluntly :-) can only say that it is very nasty :-) Why? Simply because the output is square wave, including a large number of odd harmonics. You can use Shuanglong

美国TI公司的protel 元器件库，在应用中需要更新，本人收集了最新的版本共30M，为提高上传速度分六次上传。文件名依次为TI_1到TI_6。希望大家设计电路板时少走弯路。由于在上传时找不到分类，所以归结为书籍一类-TI" s U.S. Treasury protel components, need to be updated in the application, I collected a total of up-to-date version of 30M, to improve the upload speed upload six hours. File name followed by TI_1 to TI_6. Hope that the design of circuit board less detours. From when can not find in the classification, it comes down to a class of books
