Syntax
The is capable of storing 128 font and bitmap files up to 16 Kbytes total.
In order to upload a bitmap to the you must first initiate the upload font
file command (0xFE 0x5E), you must then pass it a reference
identification number, which must be unique for every font on the
display module. You may then pass the display module the two byte file
system size, which needs to be transfered LSB, then MSB. This is
almost always the entire 16kB, meaning the values 0x00 0x40 0x00
0x00 must be issued. The last part of uploading a bitmap is transmitting
the bitmap file data.
For detailed instructions on uploading a file to the see Section 11 on
page 36.
NOTE This command is available but not not supported in I
Always
This command will draw a bitmap that is located in the on board
memory. The bitmap is referenced by the bitmaps reference
identification number, which is established when the bitmap is uploaded
to the display module. The bitmap will be drawn beginning at the top
left, from the specified X,Y coordinates. A directory listing of the
contents of the entire filesystem may be obtained by using the “Get
Filesystem Directory” command, see Section 11.5 on page 41 for more
detailed information.
