應用單片機的時候,經常會遇到需要短時間延時的情況。需要的延時時間很短,一般都是幾十到幾百微妙(us)。有時候還需要很高的精度,比如用單片機驅動DS18B20的時候,誤差容許的范圍在十幾us以內,不然很容易出錯。這種情況下,用計時器往往有點小題大做。而在極端的情況下,計時器甚至已經全部派上了別的用途。這時就需要我們另想別的辦法了。

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正是微軟公司售出的第一套軟件。Basic 發展到今天已經有很多版本,如 GW-Basic 、QuickBasic 、QBasic 、Visual Basic ,等等,其中,Visual Basic 是最容易學習與應用的程序語言之一。雖然最容易學習與使用,但它的功能卻非常強大,很多應用程序都是用它編寫出來的。 不是個個都能成為比爾蓋茨,但你想知道天天使用的Windows的諸多功能是如何實現的嗎?你想要編寫自己的應用程序嗎?通過學習VB就能寫出很多應用程序。
