D1移植讯为7寸MIPI屏
-
1、修改驱动源码
内核源码驱动路径：tina-d1-open/lichee/linux-5.4/drivers/video/fbdev/sunxi/disp2/disp/lcd
uboot源码驱动路径：tina-d1-open/lichee/brandy-2.0/u-boot-2018/drivers/video/sunxi/disp2/disp/lcd
因为驱动框架是一样的，我们只需要修改屏幕初始化参数就可以了。这里我修改的就是tft08006.c文件修改内核源码

这里只把重要的参数列出来了，内核设备树和uboot设备树要保持一致。

到Tina根目录下make kernel_menuconfig将下面驱动配置上
修改设备树
在twi0下增加触摸屏子节点
4、编译打包、测试
-
@yaoxiaoyao
这个屏可以直连？ -
@jordonwu 不可以，线序不一样
-
请问tft08006.c文件哪里下载？
-
@lumen
修改前的在tina-d1-h/lichee/linux-5.4/driver/video/sunxi/fbdev/disp/disp/lcd -
大佬，求一个你这个mipi屏的购买链接
-
-
@q1215200171 楼主用的应该不是原厂的
-
@lumen 或许是 看着挺像
-
@lumen 讯为的MIPI屏 淘宝有卖的三四百吧
