The blue boxes in the screenshot are layer declarations. They should start with tag “LAYER”
and followed by a number from 0 to 7. Layer 0 is default layer, which means after power on, or
reset layer, DD Micro will switch to this layer.
The lines marked into orange box are key definition lines. Each line refers to a physical row of
keys on DD Micro. Attention that in this file, all possible key positions should be explicitly
defined. It might be not mounted to a dedicated key on you layout setup, but you have still have
to define it in dd_configuration.txt file. This is because the firmware does not know which layout
you have chosen, so you have to always provide a complete setup. If you don’t want to allocate
a key definition to a key position, or you don’t connect the switch to this key, you could just write
three dots (…) to indicate this is an empty position ( No effect when it is triggered or pressed ).
In each line of key definitions, the layer information is not explicitly declared. This means the
closest layer definition before will be inherited. And the row number will be incremented by one
on each new line.
For how to set the definition for each key position, please refer the “Configuration file reserved
tag list” chapter and “What’s more you should know” chapter.
After you prepare a good dd_configuration.exe file, you could follow the steps below to
download it to your DD Micro keyboard:
1.Turn off power switch, and make sure that USB cable is not plugged.
2.Hold the most left key on top row, then connect USB cable to computer. This will switch
DD Micro to configuration mode. In this mode, you cannot use it to input.
3.Double click ddconf.exe to run the download tool, or type in the application name in
Command Line to execute it.
4.Following the instructions shown on your screen, to start the download progress. You
may need another keyboard to help you press any key to continue.
5.The download progress may take about 2-5 seconds, this is based on how many layers
you have. Please wait for a while.
6.After download progress finishes, DD Micro will switch to normal keyboard mode
automatically. Press any key to exit download tool and time to try with your new key
definitions!
