使用T113S3 tina linux驱动ST7701S RGB长条屏幕，显示lvgl demo分两半问题
-
问题卡了两周，各位路过的大佬帮忙看看呗！感激不尽
使用T113S3 tina linux驱动ST7701S RGB屏幕，打开lvgl demo，显示分了两半的问题：
通过指令保存的图片是正常的：
echo 0 > /sys/class/disp/disp/attr/disp echo /data/1.bmp > /sys/class/disp/disp/attr/capture_dump
厂家给的参数：
HS:10 HBP:30 HFP: 50
VS:2 VBP:15 VFP:17
400*960DTS部分配置如下：
