MAJOR UPDATE for K3 owners!
The "partial area" updates used in Sparkle-1.0 (for which the source code had been lost and was recently found), are MUCH faster on a K3 than using eips, and much faster than using the /proc update interface.
After replacing the eink update method for 4-bit screens (DX, DXG, K3), hoser-2.0 is many times faster on a K3, EVEN THOUGH it is not recommended for FULL SCREEN updates like this. That means that it will be EVEN FASTER if we use it to only update known changed (dirty) areas of the screen.
It does not make the DX or DXG run any faster though -- they use older 2.x firmware. Perhaps it would be faster on a DXG that was updated to 3.x firmware.
If you have a K3, go get hoser-2.0 now! Soon, I will update all the old demos to run MUCH faster on the K3. Things will only get BETTER with this new change in update method.
Enjoy!
