 		 #174386 - Seperate display processor
Responding to: ???'s previous message
Michael Karas said:
Just how is the current product configuration synthesizing these "pictures"?

Wouldn't it just make sense to slice out the display driver part of the current implementation, including the picture generation, and move that to another MCU and then put an interface from the main controller to the new display controller. If I were doing this I think that my preference would be to couple the two CPUs via a hardware peripheral fast SPI connection.

Michael Karas

Currently it is all in the firmware, fonts in two sizes, and some glyphs.
The SPI connection seems the most feasable. The F310 has 16kB of flash, enough to do the display even with more pre-compiled glyphs.
Thank you.
