Review of the timings

[erenard]

Hi, After trying to use it with these kind of cheap devices, I had to review the timings. Other devices, like a USB composite AV worked and allowed me to debug.

I understand its a relatively big change, but if you try it you will see it work.

Anyway thanks for the original code, my whole project needs these kind of screens.

Question do you think these fixes could possibly fix some timing issues that occur with using chips that have PSRAM? (Timing issue is that as soon as you start using the PSRAM for stuff if you have the Cache fix enabled it losses sync and the image begins to scroll on the screen.)

@erenard thanks. I just had this very issue and your changes fixed it 😃
