Strange behaviour Crow Panel HMI Advanced 7inch Lesson4 - displaced sccreen
Hello.
I'll say right away - I'm a complete beginner..
I have a Crow Panel Advanced HMI 7 inch panel in my tests.
During lesson 4 - photos from SD CARD - the photos are loaded but the image is shifted a few dozen pixels to the left. I hope you can see it well in the photos I'm attaching.
The panel resolution is set correctly - I'm attaching the code
Second thing - with the standard parameter
cfg.freq_write = 21000000; the image flickers when loading - it's like it's waving.
After setting cfg.freq_write = 14000000; - everything is ok
Setting below 14 only causes a white screen

Sry for missing <code> i cant add it, dont know how.
