Re: RA8875 display problems with T4.x - a visual study

Ken: If you're like me, you order "pairs" of mpu's "just in case"...it's saved my bacon more than once. Anyway, I'm not sure it's worth $10. If I use just the 4.1, I tie up about $65 for backups. If I use both the 4.0 and 4.1, I'd tie up $111 ($65 + $46). It would be interesting to see if there's a performance improvement, however.
The other alternative that sounds interesting is to use an RP with its HDMI video capability for the display. It's plenty fast enough, but I know nothing about programming them, the IDE, or the library support.

Maybe one of the mcu's could be a T4.0 to save some bucks?
