Summary
This document describes the hardware and software produced by Dialog Semiconductor to allow users to evaluate E Ink
segmented displays along with the DA852X family of driver ICs from Dialog Semiconductor. The system is designed with
the following objectives:
•
To assess the suitability of the E Ink technology for a given product concept,
•
To quickly evaluate the performance of the display (for example, in terms of its contrast ratio, look
and feel, and transition speed),
•
To design the display (particularly its size, segmentation, and other parameters),
•
To evaluate different driving waveforms, and
•
To start the design of the software for the microcontroller being used in the system.
The software uses a PC operating Windows 2000/XP with a USB1.1 or USB2 interface. The software has not been
extensively tested on Windows Vista, but has been shown to function. See Section 3.1.2
1.1
Product Lineup
The DA852X E Ink Evaluation Kit series has been produced to allow evaluation of the DA852X series drivers
These currently comprise:
Product Lineup
Device P/N
DA8521-00-BC-1
DA8522-00-BD-1
DA8523-00-BE-1
DA8524-00-BF-1
All kits include a CD ROM containing documentation and driver files. The driver software uses a simple graphical
interface, allowing the DA852X series board to be controlled via a USB port of a PC. The software is the same for all the
different kits.

It is probably easiest to see this in action by considering the following waveform, taken from one of the predefined waveforms. The parameters have been adjusted to give a larger number of transitions, and do not necessarily produce a good image transition. © Dialog Semiconductor 2008. All rights reserved.
