这是用VHDL来设计80C51的开发过程和代码！ 处女作，大家一定要顶啊！...

51汇编语言缩进程序,格式化出漂亮的51汇编代码-51 assembly language brings procedures, formatting beautiful out of the 51 assembly code

用C51中I/O口摸拟串口-simulate serial port with I/O port in language of C51

Ti 公司低功耗RF芯片选型资料.其中有13.56-27MHz,300-1000MHz ,2.4GHz等等芯片选型参考-Ti low-power RF chip companies Selection information. Among them, 13.56-27MHz ,300-1000MHz, 2.4GHz chip, etc. Selection of reference

整个控制过程中最关键的部分是与PC和终端的通讯过程。有关两方面通讯的详细的协议参见PC和终端的文档-51

usb host的驱动程序,用于实现usb端口的初始化等-usb host driver for the usb port initialization realize such

c8051f020实现4个　产UART　口-C8051F020 realize four production UART port

由于输出的是方波，比较难听:-) 只能说是非常难听:-)为什么呢？只因为输出的是方波,包含了大量的奇次谐波。 你可以用双龙的"虚拟仪器"分别产生正弦波、三角波和方波听一下，正弦波感 觉就比较纯正，而方波则要多难听有多难听！-As the output is a square wave, more bluntly :-) can only say that it is very nasty :-) Why? Simply because the output is square wave, including a large number of odd harmonics. You can use Shuanglong

ADC0809驱动程序，可以直接使用。 我在实验中已多次使用过。-ADC0809 driver can be used directly. In the experiment I have used.
