實物的LCD12864顯示屏與仿真不一致?

ID:1107719 · 發(fā)表于 2024-4-13 21:04

rt。算是從新手到焊板子一路沖過來了。這回板子也焊好了，也下載成功了。最后...顯示屏顯示的和仿真的不一致，這肯定是實物和仿真的器件不一致的問題了，估計的改代碼之類的。但我現(xiàn)在毫無頭緒。求教。

仿真圖
實物圖

附帶上次提問后折磨了很久以后才弄得原理圖

用的是hs12864-15c差點忘了帶實物得編號了

這個是怎么處理？是我換顯示屏還是改代碼？還是我焊接得有問題？？？

自頂一下。有沒有人有頭緒QAQ

實物屏帶字庫，仿真屏無字庫，兩者時序指令不能通用，就是這么回事。。
要與仿真一致，就要換成無字屏。
要實物為主，就要改寫代碼。

以上是源代碼

實物屏帶字庫，仿真屏無字庫，兩者時序指令不能通用，就是這么回事。。
要與仿真一致，就要換成無字屏。
...

嘶...如果要改的話，具體要怎么改？買個無字屏的話要買怎樣的？如果要改時許的話又要怎樣？？也算是第一次從代碼到仿真再到實物了。這個我還真沒留意。

12864LCD常用的無字庫屏是KS0108驅(qū)動，常用的有字庫屏是ST7290驅(qū)動。
相應(yīng)代碼本壇都能搜到。

仿真屏為左半屏和右半屏驅(qū)動，工程屏不是呵。結(jié)論：此屏非彼屏。
