#define LCD_Data P1

HC595不是给数码管用的吗？对吧？所以这个引脚应该没影响吧？
我试了一下，咋不行呢？上面连接屏幕的引脚我弄好了，这个没错。不知道为啥不行。

你都有89c52的了，移植下很快的

你太看得起我了，我就是没弄出来，才跑来问的{:lol:}

sbit P_HC595_SER = P5^0; //pin 14 SER data input
sbit ...

这个HC595是试验箱的，是给数码管用的。

你试过官方这个代码可以用吗？

可以用的，在官方的STC实验箱4 用STC15W4K。

STC15W4K32S4 驱动st7920的例子谁有啊，最好是测试过可以用的。
