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