Seems that the hard work from Mifmasterz was a bit premature. It works and the displays all appear albeit wrong colours but there is some speed issues and lack of invalidation of the elements.
I can build my code and run it and see the screens but the response to buttons is not fluid. Sometimes they don’t appear to draw back to the upstate. There is also a huge delay in touch response. The touch is fast via the driver and I can see this in the debug but the graphics are slow.
I think if we can use the same XML layouts but use the new UI elements to create the buttons, etc, that might be a better way forward.
If anyone wants to grab the source code and have a play, you can find it here. The driver is setup for my 1024x768 LCD but easy enough to make changes to the driver and the XML files.
