1.0 INTRODUCTION
The DLP-ECON-F1 E Ink Display Controller is designed to make easy work of driving E Ink's 1.73-inch
Mobius display. This module consists of the electronic components necessary to correctly update the
image on the e-paper display via a simple TTL serial interface typically found in low-cost
microcontrollers. The DLP-ECON-BP BoosterPack can be controlled by two types of host: PC GUI via
USB (Virtual COM Port), or the Texas Instruments LaunchPad.
In a typical usage scenario when the host is a PC, the GUI is utilized to create and send over full-screen
displays including barcodes and icons via the USB interface. The GUI can also import *.bmp bitmaps
which can be used in full-screen displays. When the host is a TI LaunchPad (or small microcontroller),
non-full-screen control features are used to update the contents of the display: Clear Display, Display
Text, Icon On/Off and Global Update via non-volatile memory.

This module consists of the electronic components necessary to correctly update the image on the e-paper display via a simple TTL serial interface typically found in low-cost microcontrollers. The DLP-ECON-BP BoosterPack can be controlled by two types of host: PC GUI via USB (Virtual COM Port), or the Texas Instruments LaunchPad.
- Page 2 2.0 QUICK-START GUIDE The DLP-ECON-BP BoosterPack can be controlled via two types of hosts: USB connection to a PC or by a TI LaunchPad. Using either method, power to operate this BoosterPack is sourced via the USB interface on the TI LaunchPad; therefore, a TI LaunchPad is required for normal operation.

- Page 16 5.1 PING Use this feature to verify that you have successfully connected the GUI to the DLP-ECON-BP BoosterPack. This command also returns the current firmware version. 5.2 CREATE FULL-SCREEN IMAGES The GUI has several features that make it easy to create images that will fill the E Ink display. These images can then be saved to a PC hard drive and loaded to the BoosterPack for presentation on the E Ink display.
- Page 17 Use this feature to request a CRC check of the frame buffer. Note that this feature returns valid CRC’s just after transferring images to or from the target device. Once a Global Update or Local Update has been performed, the CRC value internal to the target device becomes invalid. ©2014 DLP Design, Inc. September 2014: Vers1.0 Page 17...
