I am looking for info on the interface to the EPD controller in the Nook Touch and Sony PRS-T1.
Both use the i.MX508, but seen from the Java interface, use different drivers. The Nook uses separate calls into a N2EpdController function, the Sony adds an updatemode parameter to its display functions. At some point a JNI interface passes the control to the kernel.
Does anyone know if there is a standard way/code available to steer the EPD controller in the i.MX508?
If the makers of eReaders also modify the kernel, I think the case is lost, otherwise there would be a possibility to write a common Java interface for eReaders using this chip family.
With your information, you could bring e-ink a step further by assisting app developers with suitable WebKit/WebView classes.
