ILI9163C 模拟8080无法驱动LCD！

口天土立口

调了很久，没调通，用的是厂家提供的51模拟8080代码，但我的主控是stm32f103zet6，修改了相应管脚的驱动代码，但驱动不起来！
麻烦各位大神支招！万分感谢！

驱动终于调出来了，原来是我的数据线互相短路了，另外，我的板子，居然有两根控制线的引脚是坏的！多谢各位的知道！

我的时序也参照了原子哥的OLED 8080时序，速度方面，应该是没问题的！

既然是模拟，建议按显示控制器的时序来，更简单。

我整了好几天，还是没搞出来，直接用楼主的程序还是不行，奇怪了，然道我硬件焊错了？

请问箭头处是1脚吗？

我们的驱动IC是一样的，但分辨率参数是不同的，我用的不是你这款！你需要修改某些参数设置，对照着手册，照着命令参数修改初始化设置！

我不知道你的这个是不是1脚！

这三条设置依据是什么？

写寄存器函数，形参是寄存器的地址，你查一下数据手册就知道这个寄存器是干什么用的，我当时都是一个寄存器一个寄存器地址的对比，了解他们的作用，然后修改成我屏幕的参数！

楼主，你好，我这边的ILI9163C驱动各方面也正常，读取各个寄存器时值也正常。
但是，读取点颜色时，数据不正常。和当前的显示颜色不符。
你有遇到这个问题吗？怎么解决的？
