C51源程序集锦 This a demo program showing a way to perform simultaneous RS-232 transmit and receive using only one hardware timer. The transmit and receive routines divide each bit time into 4 slices to allow synchronizing to incoming data that may be out of synch with outgoing data.

以CPLD器件EPM7128SLC84-15为核心实现的简易数字频率计,采用在一定时间内对数字脉冲计数的方法,可直接测量TTL电平的数字脉冲信号的频率、周期和脉宽。其他一些信号可经过信号预处理电路变换后测量。 量程:1Hz~999999Hz 输入信号:(1)TTL电平数字脉冲信号;(2)方波/正弦波,幅度0.5~5V 显示:七段数码管显示频率(Hz)和周期/脉宽(us) 控制:两个拨码开关切换三种工作模式:测频率,测周期,测脉宽

应用单片机的时候,经常会遇到需要短时间延时的情况。需要的延时时间很短,一般都是几十到几百微妙(us)。有时候还需要很高的精度,比如用单片机驱动DS18B20的时候,误差容许的范围在十几us以内,不然很容易出错。这种情况下,用计时器往往有点小题大做。而在极端的情况下,计时器甚至已经全部派上了别的用途。这时就需要我们另想别的办法了。

In c++ risks is a reference to a variable which exists i.e. one 2nd name for the same variable. This program is broken up into functions.露the function hand constitutes the entrance point of the program, firstly there is the function message which us affiche hello , and the second function produced 露procedure affich_calcul, one declared the prototype and one it definite after one made the call has this function.

Basic正是微软公司售出的第一套软件。Basic 发展到今天已经有很多版本,如 GW-Basic 、QuickBasic 、QBasic 、Visual Basic ,等等,其中,Visual Basic 是最容易学习与应用的程序语言之一。虽然最容易学习与使用,但它的功能却非常强大,很多应用程序都是用它编写出来的。 不是个个都能成为比尔盖茨,但你想知道天天使用的Windows的诸多功能是如何实现的吗?你想要编写自己的应用程序吗?通过学习VB就能写出很多应用程序。
