I’ve had a blast with the Phillips versions using Lynch’s code, and just recently tried out these “new” Epson displays.
For what it’s worth, I found I couldn’t write the pixels in the “Type A” style of 3 bytes for 2 pixels, and ultimately had to hack the code to accommodate “Type B” style of 2 bytes for 1 pixel, with 4 bits wasted per pixel. This works, quite well in fact.
Regarding display rotation, I’m afraid I’ve only been able to do that at compile-time with #defines for RASET and CASET, in addition to offsets and sign-changes for the coordinates, as appropriate to produce the desired behavior.
No public wish lists :(
