MSP430无法驱动OCMJ15X20D
直接移植的公司给的51程序代码，但是无法显示，公司说是可以去掉读的函数，直接写入就好，就现在51上测试成功，可以显示然后直接粘贴到430上，对延时和串口进行修改，但是一直是没有结果。。请教各位啊
51程序，可以正常显示
PS：删除了读，这个算是最简单的显示程序了吧！

下面是430程序。。和51程序一样只是增加了精确的延时和修改了端口，可以和51程序进行对比

这程序我感觉很简单了，基本上和51的是一样的，但是始终无法显示。请教各位啊
lcd_cs1 =0; 能编译通过？
430不能直接位操作吧 dalarang 发表于 2013-3-18 08:33 static/image/common/back.gif

亲，前面的哪个是51的代码哦。430的代码在后面类 标记！mark
！！
