1Summary
ThisdocumentdescribesthehardwareandsoftwareproducedbyDialogSemiconductortoallowuserstoevaluateEInk
segmenteddisplaysalongwiththeDA852Xfamilyof driverICsfromDialogSemiconductor.Thesystemisdesignedwith
thefollowingobjectives:
•Toassessthe suitabilityof the EInktechnologyforagiven productconcept,
•Toquicklyevaluatethe performanceof the display(forexample,intermsofitscontrast ratio,look
and feel,and transition speed),
•Todesign the display(particularlyitssize, segmentation, and otherparameters),
•Toevaluatedifferentdriving waveforms,and
•Tostartthe design ofthesoftwareforthe microcontrollerbeing used inthe system.
ThesoftwareusesaPCoperatingWindows2000/XPwithaUSB1.1orUSB2interface.Thesoftwarehasnotbeen
extensivelytestedon WindowsVista,but hasbeenshowntofunction.See Section 3.1.2
