使用AT89C52单片机，12MHZ晶振，P0口读入AD值，P2口作AD控制，用共阳LED数码管， P1口输出段码，P3口扫描，最高位指示通道（0-7）。-AT89C52 single-chip microcomputer use, 12MHZ crystal, P0 I read into the AD value, P2 for the AD population control, with a total of Yang LED digital tube, P1 port output above code, P3 port scan, the maximum bit instructions channels (0-7).

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

系统按键显示都具有,不同的I/O口,具有很大的参考价值-System button shows have different I/O port, and it is very useful

这是用PIC单片机做的DTMF信号解码，用的是汇编语言。已经通过实验了。有兴趣的人可以看一下。-This is a single-chip microcomputer PIC to do with the DTMF signal decoding, using assembly language. Has passed the test. Those who are interested can look at.

主要讲了单片机是使0832产生正弦波功能，十分好。-Major topics of the 0832 microcontroller is to generate sine wave function very well.

I2C的程序 数据传送 非常详细的注释 C语言的 其他的就不用多说了吧-I2C data transmission procedures very detailed notes of the C language other on the right to say the least
