Is it hard to create similar ebook.so-s for 505 version? (You can quickly get the original 505 ebook.so from here
I also edited ebook.so to play around with the orientation, but I'm not sure if those are the functions called (EinkSetOrientation and ebookEinkDoRotate) by Fsk.
JS code calls ebook.rotate, which, I guess, is eBook_Rotate from ebook.so. But you probably already know that.
but when control comes back to tinyhttp it resets back to the normal orientation.
I wonder, why would anyone program it like this...
