Can you shed some light on which other controllers are going to be supported by the library?
In addition to the KS0108 and compatibles, the SED 15220 controller is supported in the current version.
Some work has been started on a number of other LCD controller chips.
The KS-0713 is coded but we don't have a controller to test this with.
Some work has been done for the SED1330 but this is a complex beast and it may be a while before its ready.
There is a prototype of the Nokia 6610 display working with the library although the code is not ready to release (it was done primarily as an experiment to explore color support in the library).
It would be interesting to hear what displays would be most appealing. If you want to use a display that is not yet supported then please post a reply saying why you chose that display along with links to product sources.
Priority for development depends on lots factors, including the potential popularity of the display, the development effort needed to integrate, and the availability of samples to test. The latter does have significant weight and if a couple of samples of a panel were sent to Bill and me, that will help to peak our interest (You can PM me or Bill for details)
