将单片机的IOA0~IOA7分别接按键S1~S8连接到高电平上。此时，如果某个按键被按下，对应的I/O端口就会输入高电平进单片机，即按键S3按下，IOA2会输入高电平进单片机-Will Singlechip IOA0 ~ IOA7 access keys, respectively, S1 ~ S8 is connected to high on. At this point, if a button is pressed, the corresponding I/O port will enter into the high single-chip, that is, S3 button press, IOA2 will enter into single-chip high

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
