W 1 Width
H 1 Height
D (width*height)/8Data
Description Drawing a bitmap to the , without first uploading the image to the
memory can be a very useful feature for drawing images that are not
used very often. In order to accomplish this, you must supply the
display module with the X,Y coordinates, representing the top left
corner of where you would like to draw the bitmap on the screen, as
well as the width and the height of the bitmap. After you have supplied
this data you may then upload the bitmap data to the . The length of this
file is the bitmap width multiplied by height, divided by eight. The
bitmap data is encoded into bytes horizontally and is transfered the
same as if you were uploading a file, see Section 11 on page 41 for
more information about transferring data to the display module.
NOTE Drawing a bitmap directly to the display is supported by flow control.
This command is available but not support in I 2 C mode.

8 Bar Graphs and Drawing
8.1 Introduction
Supplementary to the ability of the to display bitmaps and fonts, the also allows for a robust 2D drawing
environment. With the ability to draw by pixel, line or rectangle, as well as the ability to continue a line to
form a polygon, we are certain that you will spend less time, developing and creating better looking projects.
With the addition of custom bar and strip graphs, you are sure to find the right tools to make any graphical
layout a success.
