16*16点阵的，觉得这个里面用 指针来查找数组蛮好的 。

单片机最小系统，两位LED数码管由串口输出接两个164驱动，Lout,Rout为左右声道输出，SET， ALT0， ALT1为三个按键，也可自己在开始的I/O定义改成你想用的I/O口；12M晶振，若用89C51则只可装下约14首歌曲，用89C52则可装下近40曲-The smallest single-chip system, the two LED digital tube by the serial output driver 164 then two, Lout, Rout output for the left and right channels, SET, ALT0, ALT1 three buttons can also be their own at the beginning of the I/O definition change you want to use the I/O port 12M crystal, if one uses a 89C51 only loaded about 14 songs can be loaded with 89C52 under near 40

TLC549是一种采用8位逐次逼近式工作的A/D转换器。内部包含系统时钟、采样和保持、8位A/D转换器、数据寄存器以及控制逻辑电路。TLC549每25uS重复一次“输入―转换―输出”。器件有两个控制输入：I/O CLOCK和片选（CS）。 内部系统时钟和I/O CLOCK可独立使用。应用电路的设计只需利用I/O时钟启动转换或读出转换结果。当CS为高电平时，DATA OUT处于高阻态且I/O时钟被禁止。 -TLC549 is a used 8-bit successive approximation type of work the A/D converter. Contains the internal system clock, sample and maintain, an 8-bit A/D converter, data register and control logic circuit. TLC549 each repeat 25uS
