8 Bar Graphs and Drawing
8.1 Introduction
SM 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.

Parameters
Drawing a bitmap to the GLK12232-25-SM, 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
GLK12232-25-SM. 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 12 on page 43 for more information about transferring
data to the display module.
NOTE Drawing a bitmap directly to the display is supported by flow control.
