50黑幣
下面這個(gè)程序我編譯的時(shí)候沒問題，但仿真時(shí)頻率值（仿真結(jié)果在下面）無法顯示出來，希望有哪位大佬能幫我解答一下。
- #include <AT89X51.H>
- unsigned char code dispbit[]={0xfe,0xfd,0xfb,0xf7,0xef,0xdf,0xbf,0x7f}; //P2的掃描位
- unsigned char code dispcode[]={0x3f,0x06,0x5b,0x4f,0x66,
- 0x6d,0x7d,0x07,0x7f,0x6f,0x00,0x40}; //數(shù)碼管的字形編碼
- unsigned char dispbuf[8]={0,0,0,0,0,0,10,10}; //初始化顯示值
- unsigned char temp[8]; //存放顯示的數(shù)據(jù)
- unsigned char dispcount; //顯示計(jì)數(shù)器值
- unsigned char T0count; //T0的計(jì)數(shù)器值
- unsigned char timecount; //計(jì)時(shí)計(jì)數(shù)器值

- bit flag; //標(biāo)志位

- //頻率計(jì)算函數(shù)
