DDS9851的PDF大家有需要就下载 还有中文文档-U.S. DDS9851 the PDF there is a need to download the document there are Chinese

波形发生器啊 可以产生方波，锯齿波 三角波 正弦波-Ah waveform generator can produce square wave, sawtooth wave sine triangle

这是点阵程序 个人认为先学点阵再学lcd比较好 p0 p2分别接16*16点阵的高八位和低八位(纵向取模) p3口低四位接4-16线译码器（74ls154）译码器低电平为列选 消除鬼影的方法：-This is the program individual lattice lattice before you think lcd is better to learn p0 p2, respectively, then 16* 16 lattice of high and low 8 8 (vertical modulus) p3 I received a low four 4-16 Line Decoder browser (74ls154) low-level decoder for the elimination of ghosting out the election approaches:

这是本人学习avr的一点成果吧{ 硬件mega8l，8个led共阳极接到PORTD。3位拨码开关接到PINB2,PINB1,PINB0,选择显示内容，PINC4接方向开关，使得正反向摇动都显示正向字，每次显示4个8X8点阵汉字（自己编制的），内附：原理图。实物图片，给有兴趣的朋友-This is my point to learn the outcome of avr bar (hardware mega8l, 8 Ge led a total of anode received PORTD. 3 DIP switches received PINB2, PINB1, PINB0, choose to display the content, PINC4 then switch the direction of making the pros and cons to the rock show that positive words, each show four 8X8 dot matrix characters (self-compiled), the enclosing : Principle diagram. Physical picture, to interested friends
