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:

利用单片制作信号发生器，该源码是针对51+DAC0832，所产生的一系列波形，有正弦波、方波，并把相应的波形打印到lcd上显示-Making use of single-chip signal generator, the source for 51+ DAC0832, a series of waves generated, there are sine wave, square wave, and the waveform corresponding to the lcd display print

使用国产CH341A芯片实现USB转串口，完全兼容AVR JTAGICE，可以自动升级。 支持芯片: ATmega16(L), ATmega162(L), ATmega169(L or V), ATmega32(L), ATmega323(L), ATmega64(L), ATmega128(L). 原理图还附加了RS232接口，可以方便用户自主选择串口或USB下载程序。 还附加有可自动升级的HEX文件-The use of domestically produced CH341A chip USB to serial port, fully compatible with the AVR JTAGICE, can be automatically upgraded. Support chips: ATmega16 (L), ATmega162 (L), ATmega169 (L or V), ATmega32 (L), ATmega323 (L), ATmega64 (L), ATmega128 (L). Schematics also added a RS232 interface, can easily users to choose the serial or USB download. Additional there is also automatically upgrade the HEX file
