我用的是44b0,就是当单片机使了，程序调了好长时间，就是不显示，大家帮我看看，谢谢啦，还有，液晶显示的静态和动态有什么差别？<br /><br />这个程序里，我没有让它显示汉字，我想先让它全屏都亮（先试试好不好使），然后再显示汉字，所以，hp()程序我给修改了。<br /><br />#define setA0 rPDATE |= 0x0008;//A0=1 <br />#define clrA0 rPDATE &= 0xfff7;//A0=0<br /><br />#define setE1 rPDATE |= 0x0040;//E1=1 <br />#define clrE1 rPDATE &= 0xffbf;//E1=0<br /><br />#define setE2 rPDATE |= 0x0020;//E2=1 <br />#define clrE2 rPDATE &= 0xffdf;//E2=0<br /><br /><br />#define setReset rPDATE |= 0x0080;//Reset=1<br />#define clrReset rPDATE &= 0xff7f;//Reset=0<br /><br /><br />#define setR rPDATE |= 0x0010;//R/W=1<br />#define clrR rPDATE &= 0xffef;//R/W=0<br /><br />#define Data rPDATC ;<br /><br />#define fuwei (0xe2);<br />#define kxshq 0xaf;<br />#define gxshq 0xae;<br />#define dtqd 0xa4;<br />#define jtqd 0xa5;<br />#define zkb1 0xa9;<br />#define zkb2 0xa8;<br />#define szx1 0xa0;<br />#define szx2 0xa1;<br />#define xmsstop 0xee;<br /><br /><br />extern unsigned char bmp1[];<br />extern unsigned char bmp2[];<br />extern unsigned char bmp3[];<br /><br /><br /><br />unsigned char bmp1[]=<br />{<br />/*-- 文字: 中 --*/<br />/*-- 宋体12;
