实物的LCD12864显示屏与仿真不一致?

ID:1107719 · 发表于 2024-4-13 21:04

rt。算是从新手到焊板子一路冲过来了。这回板子也焊好了，也下载成功了。最后...显示屏显示的和仿真的不一致，这肯定是实物和仿真的器件不一致的问题了，估计的改代码之类的。但我现在毫无头绪。求教。

仿真图
实物图

附带上次提问后折磨了很久以后才弄得原理图

用的是hs12864-15c差点忘了带实物得编号了

ID:1107719 · 发表于 2024-4-14 00:05

这个是怎么处理？是我换显示屏还是改代码？还是我焊接得有问题？？？

自顶一下。有没有人有头绪QAQ

实物屏带字库，仿真屏无字库，两者时序指令不能通用，就是这么回事。。
要与仿真一致，就要换成无字屏。
要实物为主，就要改写代码。

实物屏带字库，仿真屏无字库，两者时序指令不能通用，就是这么回事。。
要与仿真一致，就要换成无字屏。
...

嘶...如果要改的话，具体要怎么改？买个无字屏的话要买怎样的？如果要改时许的话又要怎样？？也算是第一次从代码到仿真再到实物了。这个我还真没留意。

12864LCD常用的无字库屏是KS0108驱动，常用的有字库屏是ST7290驱动。
相应代码本坛都能搜到。

仿真屏为左半屏和右半屏驱动，工程屏不是呵。结论：此屏非彼屏。
