The entire screen is being redrawn with 24bpp. With 16bpp, only the pressed button is re-drawn.
See settings below.
I have been looking at the PE-HMI1 board and the Hello World demo. It uses 16bits RGB565.
The GUIX User Guide for the Renesas Synergy Platform does not explain how to optimize memory settings for a desired graphics screen size and bpp.
I am guessing more memory is needed for the higher resolution graphics.
Where do I find the instructions for setting up GUIX and the Display Driver for screen size and resolution?
Thanks,
Bruce
