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.  Full-screen images are about 20K bytes in size and take about 1 second to upload to the 
BoosterPack. 
 
 

5.3  CLEAR DISPLAY 

 

This function will cycle the entire display from black to white then black to white again.  This serves to 
both clear the display and rejuvenate any locations in the display that may have been overdriven by 
other hardware. 
 
 

5.4  GLOBAL UPDATE 

 

This function is used to take a full-screen image (20K bytes) in the frame buffer and load it to the display 
all at once.  Issuing a Global Update command to the DLP-ECON-F1 will invalidate the CRC for the 
image that was held in the frame buffer before performing the update to the E Ink display. 
 
 

5.5  LOCAL UPDATE 

 

This function is called after first having sent one or more small updates to the frame buffer.  Examples of 
this type of data update would be an icon update (on/off) or text placement.  The only pixels that change 
on the display are those required to change by the new data.  Issuing a Local Update command will 
invalidate the CRC for the image that was held in the frame buffer before performing the update to the  
E Ink display. 
 
 

5.6  LOAD IMAGE 

 

Used to load icons or images from the PC's hard drive to the working window in the GUI. 
 
 

5.7  SAVE IMAGE 

 

Used to save icons or full-screen images to the PC's hard drive from the working window in the GUI.
