我的程序现在是这样的
不能定义外部的int和long类型，只能定义char类型的
定义一个long类型时候发现只能把最高字节写入
EMC_CTRL = 0x00000001;
PCONP |= 0x00000800;
PINSEL4 = 0x50000000;
PINSEL5 = 0x05050555;
PINSEL6 = 0x55555555;
PINSEL8 = 0x55555555;
PINSEL9 = 0x50555555;
// delayMs(1, 100);
EMC_STA_CFG0 = 0x00000080;
EMC_STA_WAITWEN0 = 0x2;
EMC_STA_WAITOEN0 = 0x2;
EMC_STA_WAITRD0 = 0x1f;
EMC_STA_WAITPAGE0 = 0x1f;
EMC_STA_WAITWR0 = 0x1f;
EMC_STA_WAITTURN0 = 0xf; |
