從業(yè)十年，教你單片機入門 第10講：
目前，幾乎所有的初學者在學習和上機練習C語言的時候，都是在電腦上安裝VC這個調(diào)試軟件，在源代碼里只要調(diào)用打印語句printf就可以觀察到不同的變量結(jié)果，挺方便的。但是現(xiàn)在我要提出另外一種方法，學習單片機的C語言，不一定非要用VC調(diào)試軟件，也可以直接在堅鴻51學習板上學習和上機練習的。我可以做一個調(diào)試模板程序給初學者使用，利用8位數(shù)碼管和16個LED燈來顯示不同的變量結(jié)果，利用3個按鍵來切換顯示不同的變量，這樣就能達到類似在VC平臺下用printf語句來觀察變量的效果。甚至我個人認為這樣比用VC調(diào)試的效果還更加直觀?，F(xiàn)在重點介紹這個模板程序的使用。
在模板程序里，初學者只需要在主程序的初始化區(qū)域填入自己練習的C語言代碼，最后把需要觀察的變量賦值給窗口變量就可以了，其它部分的代碼屬于模板的監(jiān)控調(diào)試代碼，大家暫時不用讀懂它，直接復制過來就可以了。上述所謂的“賦值”，就是“=”這個語句，它表面上像我們平時用的等于號，實際上不是等于號，而是代表“給”的意思，把“=”符號右邊的數(shù)復制一份給左邊的變量，比如“a=36;”就是代表把36這個數(shù)值復制一份給變量a，執(zhí)行這條指令后，a就等于36了。這里的分號“;”代表一條程序指令的結(jié)束。窗口變量有幾個?有哪些?一共有10個，分別是GuiWdData0，GuiWdData1，GuiWdData2，GuiWdData3，GuiWdData4，GuiWdData5，GuiWdData6，GuiWdData7，GuiWdData8，GuiWdData9。這10個窗口變量是給大家調(diào)試專用的，8位數(shù)碼管可以切換顯示10個窗口變量，最左邊2位數(shù)碼管代表窗口變量號，剩下6位數(shù)碼管顯示十進制的窗口變量數(shù)值，另外16個LED實時顯示此數(shù)據(jù)的二進制格式。最左邊2位數(shù)碼管從“0-”到“9-”代表從第0個窗口變量到第9個窗口變量,也就是GuiWdData0依次到GuiWdData9。用S1和S5按鍵可以切換顯示不同的窗口變量，按住S9不放可以觀察到當前窗口變量的十六進制格式數(shù)據(jù)，松開S9按鍵后，又自動返回顯示當前窗口變量的十進制數(shù)據(jù)。
該模板程序是基于堅鴻51學習板，現(xiàn)在跟大家分享這個程序，要讓這10個窗口變量分別顯示10,11,12,13,14,15,16,17,18,19這10個數(shù),用S1按鍵可以切換顯示從小往大的窗口變量號，用S5按鍵可以切換顯示從大往小的窗口變量號。再強調(diào)一次，大家只需要關注主程序main函數(shù)的初始化區(qū)域就可以了，其它的代碼請直接復制過來，不用理解。比如：
void main() //主程序
{
//...初始化區(qū)域
while(1)
{
}
}
