Bug fixed. Now it is stable 🙂
Test frame rate again, it is around 20~20.5fps, emm, it does not reach my target 24fps, still have space to optimize.

I send two pictures to the screen in a loop and use my phone record 5 seconds(slow motion), count frame by frame, it is 102 frames.

Next step, write Linux driver and use frame buffer driver.

PS: looks like it is so smoothly from blog 1 to 6, step by step… actually the develop process is so painful and hopeless… I spend over two months full time on this. I had the thought of giving up over thousands times…
I can not go this far without my family’s encouragement.
Finally, the result is so beautiful, can not believe I made this! crying like a baby. T-T
