The DSP-7 controller has many pictures, mainly for the Selection Menu, some buttons and others. These pictures are stored in flash memory. The user can update it with own pictures by writing compressed pictures on an SD card. This SD card is inserted in the Display's SD slot. During power-up the pictures from the SD card are written into flash.
The original pictures are available HERE. You may change all of them or just a few pictures.
! Always make a backup copy of the flash memory using the booatloader before modifying the pictures !
Generating pictures is a five-step process:
Step-1:
Draw pictures with these names and these resolution (x/y):

| a2 | 310 x 120 | Antenna/Band menu, antenna-2 |
| a3 | 310 x 120 | Antenna/Band menu, antenna-3 |

Step-2:
Save the picture as a bitmap in 5-6-5 format. Many graphic programs (i.e. GIMP) can export 5-6-5 bitmaps. The file extension of the bitmap must be .bmp
Step-3:
Compress the bitmap files. This works only in a Linux console.
Copy all bmp files into a separate folder. Copy also THIS program into this folder and give it executable rights (chmod 755 bmp2cmp)
Then execute the program (./bmp2cmp), it will convert all bmp files into cmp files.
Step-4:
copy the cmp files to a SD-card (normale size SD card, FAT32 formatted)
Step-5:
insert the SD card to the SD slot in the display.
Switch ON the DSP-7,
the screen shows you the copying process of the graphic files into the flash.
When finished remove the SD-card !
