Can I use custom displays with the Picaso processor?
No, unfortunately, there are so many variants of the display driver ICs that it is difficult to have a generic PmmC file with external display settings. Picaso modules need a specific PmmC file with the display initialization settings fully built-in.
If you’re interested in using a 4D graphics processor with a custom display, please submit a ticket to contact the technical support team.
