如果你是想學計算機軟體開發的話，就不要去理會什麼單片機編程了。
但如果你是想學電子產品開發（嵌入式系統開發），那麼單片機編程就是基礎了。
電腦和單片機的區別是：電腦屬於通用計算機，而單片機是嵌入式微機。
通用計算機上的C語言和匯編編寫出來的程序是在本台計算機上運行的，當然你也可以讓它在其他電腦上運行。而單片機編程就不同了，單片機編程有專門的編譯器，不同的單片機編程軟體是不同的，而不像電腦上的c++6.0、TC或其他什麼編程軟體寫出來的程序就在本台電腦上運行，單片機的編程是在電腦上編寫程序並生成可執行文件。讓後把可執行文件下載到單片機裡面，也就是說單片機編程是面向單片機的，而通用計算機編程時面向通用計算機的。這就說明了為什麼不同的單片機需要不同的編程軟體，因為編程生成的可執行代碼都需要硬體的支持，通用機的硬體是「通用的」「兼容的」，而單片機型號不同硬體就會有差別
，所以需要不同的編譯器來支持了。
你會發現單片機編程的C語言和標准C會有差別，很多單片機C語言在標准C里是不被承認的，這個也能說明單片機和電腦的區別吧。
㈡ 51單片機編程編程問題
1.利用MCS51系列單片機指令編寫8位數x和16位數y的乘法程序，x存在片內RAM的30H中，y的低8位、高8位分別存在片內RAM的32H和33H單元，計算結果所存的單元自行安排
X(8位)

㈢ 51單片機用什麼軟體編程
開源軟體mcu8051ide 功能不是一般的強，用c語言編程，界面不輸給商業軟體，而且提供多種模擬器件如：led 數碼管，矩陣數碼管（8×8）按鍵，矩陣按鍵，甚至溫度感測器。開源的沒有任何限制，完全免費，自動生成多種燒錄文件（我們一般就用.HEX的）感覺keil c弱爆了。
安裝方法，下載sdcc（mcu8051ide是基於sdcc的）和mcu 8051 ide都安裝好就可以啦，頭文件在sdcc的安裝文件夾內（include）有些關鍵字要加兩個連在一起的下劃線比如 __interrup, __code.
頭文件與keil的不通用，比如定義P0口
在keil下是： sfr P0=0x80; 在sdcc下是： __sfr __at P0 0x80; 這個P0^1的不行，但sdcc裡面有很多頭文件8051.h 80c51.h 80c52.h等等 基本滿足要求，給stc單片機編程不用改，加一點特殊的就可以。這樣優秀的開源軟體不用真的是白不用啊。
㈣ 51單片機編程
周期2MS的方波，占空比1：2，不就是1MS高電平1MS低電平？

㈦ 單片機編程步驟
一、什麼是 nec 單片機
隨著大范疇集成電路的顯現和發展，將計算機的cpu、ram、rom、定時/數器和多種i/o介面集成在一片晶元上，組成晶元級的計較機，因此單片機早期的含義稱為單片微型計較機，直譯為單片機。單片機是一種集成在電路晶元，是採用超大范疇集成電路技能把具有數據處理本事的中心處理器CPU隨機存儲器RAM、只讀存儲器ROM、多種I/O口和間斷系統、 定時器 / 計時器 等成果(大要還包括表現驅動電路、脈寬調制電路、模擬多路轉換器、A/D轉換器等電路)集成到一塊矽片上構成的一個小而完竣的計算機系
二、nec單片機的操縱教程詳解
1、在智能儀器儀表中的操縱：在各類儀器儀表中引入單片機，使儀器儀表智能化，進步測試的自動化程度和精度，簡化儀器儀表的硬體結構，進步其性能價格比。
2、在機電一體化中的操縱：機電一體化產品是指集呆板、微電子技能、計較機技能於一本，具有智能化特徵的電子產品。
3、在實時過程式控制制中的操縱：用單片機實時進行數據處理和控制，使系統保持最佳事變狀態，進步系統的事變從命和產品的品格。
4、在人類生活中的操縱：目前國外各種家用電器已普通採用單片機代替傳統的控制電路。
5、在此外方面的操縱：單片機除以上各方面的操縱，它還遍布操縱於辦公自動化范圍、商業營銷范圍、汽車及通信、計較機外部裝備、暗昧控制等各范圍中。
以上就是為大家整理的關於單片機含義及其具體操縱教程的全部內容了。此外小編還額外為大家整理了單片機的優點：低電壓、低功耗、集成度高、可靠性高、體積小、控製成果強等。希望通過這篇文章能夠給想要了解單片機相關知識的朋友帶來一些幫助。另外大家如果想了解更多單片機的知識可以通過圖書查閱、網路查閱等方式。
㈧ 單片機編程51系統的
#include <reg51.h>
#include <intrins.h>
sbit K1 = P1^4; sbit K2 = P1^5;
sbit K3 = P1^6; sbit K4 = P1^7;
void main()
{
while(1)
{
P0 = 0xff;
if(K1==0)
P0 = 0xfe;
if(K2 == 0)
P0 = 0xfd;
if(!K3)
P0 = 0xfb;
if(!K4)
P0 = 0xf7;
}
}
㈨ 給51單片機編程序，用basic語言好還是c語言好
兄台你搞錯了，basic是操作系統上用的編程。即Visual Basic是一種可視化的面向對象的編程語言，以其編程簡單、快捷等特點，深受廣大WINDOWS程序員的青睞。而51系列單片機只有用c語言匯編語言。另外單片機的c語言又跟標准c語語言有點差別。主要是IO口、中斷及寄存器，不太一樣。
單片機c語言增加了一些基本的指令 變數的賦值是16進制，當然單片機c語言只牽涉到普通c語言的基礎部分。
但是在單片機上的C語言多了一些特定的指令,如SFR定義寄存器指令,在標准C上是沒有的; 在標准C上的有些庫,在單片機上是不支持的, 可以這么說,單片機C是標准C的子集,在這基礎上,加上了一些單片機特定的指令構成。

假設在P1口：

mov a,p1
anl a,#0fh
mov b,a
xrl a,#03h
jz mot1 ;如果cd閉合
mov a,b
xrl a,#0ch ;如果ab閉合
jz mot2
mov a,b
xrl a,#00h ;如果abcd閉合
jz mot3
jnz err ;如果不屬於上述情況
mot1:
setb p1.7
clr p1.5
ljmp next
mot2:
clr p1.7
setb p1.5
ljmp next
mot3:
setb p1.7
setb p1.5
ljmp next
err:
clr p1.7
clr p1.5
next:
