New 7" Display
Hi
Squareline demo still not working.
It is working with my old 5" display but not with my new 7" (the new version with I2C port.
Sometimes I can see a faint image on screen 1, screen 2 fading and switching. Touch doesn't work, or you can see the coordinates coming in but nothing else.
Any suggestions?

Hello @SM0PYH ,
Please change the screen driver from Arduino_GFX to LovyanGFX
and modify
into

Thanks for your answer.
I could not download the library LovyanGFX.zip
Broken link i think Best regards
https://forum.elecrow.com/uploads/122/JY9XJ2Z4TL5W.zip
Hey All,
I have the same issue as SM0PYH (7 inch screen as well), I downloaded the LovyanGFX included in the set of libraries that is on the tutorial page and none of the codes work. Now I get the following error:
base operand of '->' has non-pointer type 'LGFX'
lcd->draw16bitRGBBitmap(area->x1, area->y1, (uint16_t *)&color_p->full, w, h);
First I used the original code that said Arduino_GFX while the included library only contained an Adafruit_GFX. I sourced Arduino_GFX got the same error as SM0PYH.
I also tried the last method and failed in the above mentioned way.
Could someone please please help us out here?

Thanks for the help in advanced!
Hello,
Sorry for the broken link. You can install the library by opening the Library Manager in Arduino IDE, and searching for "LovyanGFX". Then click "install".
Hi
Thanks for your effort.
Using LovyanGFX version 1.1.12
I got the same error as Hugh_Mungus
Could you please make a copy of the demofile and make the changes you suggest, compile and publish the code for us.

Hello,
The "->" needs to be changed to ".", and the color need to add TFT_
For example, " lcd->fillScreen(BLACK);" change to "lcd.fillScreen(TFT_BLACK);"
Is there an updated 7.0" espif demo? This did not fix my issue. The code compiles and builds but faults and the display reboots.
