Crow panel 7.0" DIS08070H TOUCH ISSUE

SoumyaSoumya
in Elecrow HMI Display

So i got a new crowpanel 7 inch V3.0 display with touchscreen and tried to learn the basics through their youtube tutorial but one the 4th lesson i was stuck because the code did upload successfully but i wan unable to draw anything so if someone else has encountered similar issue kindly help me out. (I also checked the panel by uploading the default LVGL interface and the touch did work there so i think the error is in the code or the code provided in lesson 7 .)

    Dear Soumya,

    Please try to change these two parameters from the original code and see the result.

    If still not working, please use this attached example code,it's mostly the same, just modified the libraries.
    If you have any further questions, please don't hesitate to let me know.
