好不容易寫完一點(diǎn)程序，結(jié)果單片機(jī)學(xué)習(xí)板跟我玩傲嬌，代碼燒不進(jìn)去，蒼天�。。。。。。。。�！51單片機(jī)小車制作 <wbr>STEP2.2 <wbr>數(shù)碼管顯示函數(shù)
這些程序運(yùn)行出來的結(jié)果應(yīng)該是從10顯示到99.
#include
#define uchar unsigned char
#define uint unsigned int

unsigned char code WeiMa[]={0xfe,0xfd,0xfb,0xf7,0xef,0xdf,0xbf,0x7f}; //分別對應(yīng)相應(yīng)的數(shù)碼管點(diǎn)亮,即位碼
