为什么我下载了不能打开啊，我用的proteus8.0

ID:106796 · 发表于 2016-12-25 20:12

为什么显示不了数字和字符，谁能解答一下？

ID:109651 · 发表于 2017-4-14 09:22

其实根本就打不开，仿真的结果也不是上面说的那种。

怎么没有绘图子程序，，连图像数据都有？？发我学习吓呗

ID:185367 · 发表于 2017-5-21 16:39

请教楼主，汉字和英文同时显示怎么样？可以显示吗？会出现乱码吗？

图形显示不了，英文显示不了，没有解决

Hi
I want to simulate LCD128x64 ST7920 in proteus v8.9.
Where can I download its library?
Thanks

ID:666011 · 发表于 2020-6-1 20:03

这个是ST7920的封装吗？现在市面上的ST7920不都是分上下两屏嘛，也没有NC1和NC2脚啊
