请坑友门帮忙调一个4.3寸480x272的屏的驱动参数（用的mango-pi系统），或者推荐一款好用的屏
各位坑友好，最近折腾V3S的板子，要上一块4.3寸，分辨率480x272的触摸屏，型号为KD043WQTPA035-01,控制IC：ST7282,RGB接口，文档上的timing参数如下：
请问如何设置以下参数呢？（下面的是我设置的其中一套参数，但是会出现花屏的现象）

拉轰的脚踏车 说：
检查连接线问题， 是不是很长？有多长？
并不长，就是用的屏自带的排线。也不应该是板子的问题，有朋友同样板子接5寸的电容屏是OK的。

感谢各位坑友。可能是板子焊接的问题，我又换了一个上古时代的荔枝派zero，用的https://whycan.com/t_3400.html第20楼的固件，发现屏能跑起来，除了分辨率不对（固件是800x480的），屏背光有点闪，触摸没有以外都还挺好，请问分辨率在哪里改呢？

Re: 请坑友门帮忙调一个4.3寸480x272的屏的驱动参数（用的mango-pi系统），或者推荐一款好用的屏
哇酷小二 说：
如果linux用simplefb驱动，那么在uboot改分辨率，本站有帖子。
非常感谢，已经正常驱动该LCD，接下来需要去掉电阻触摸屏。我看这个屏上的电阻板没有芯片，直接连过来的，应该是要使用荔枝派zero上面自带的电阻触摸控制芯片，那么这个应该如何配置呢，还望赐教，非常感谢！
