怪事了，同一個C文件，為何編譯出來的HEX文件不同？

首先我看了教學(xué)視頻后，估計打算不看源程序就自己編寫一下先

#include <reg52.h>
void main()
{
P0 = ~0x3f;
while(1);
}

復(fù)制代碼

結(jié)果LED 不亮。

對比一下光盤里的源程序，覺得功能實現(xiàn)上沒多大區(qū)別啊。

然后copy源程序來編譯，就得出下面兩種結(jié)果。

HEX 文件1：把源程序copy到我的工程文件里編譯，LED不亮。

HEX 文件2：打開光盤的工程文件編譯。LED 亮。這是光盤里源程序編譯出來的HEX文件

你確定編譯時芯片有沒有選對？

ID:290381 · 發(fā)表于 2018-3-11 15:45

搞定了，原來是選了不同的芯片，所以出現(xiàn)不同的編譯結(jié)果。

謝謝。

我發(fā)現(xiàn)其實我芯片是選對的。在KEIL 4 設(shè)置的芯片是amtel 的at89c51，編譯出來的程序能把led點亮
后來我再裝了KEIL 5的最新版本，但這個版本沒有amtel 的at89c51可選，只好選了microchip的at89c51，結(jié)果編譯出來的結(jié)果就不能點亮LED了。

另我用的是普中科技的8600 V2.2 開發(fā)板。
