HID Character Mapping
Sometimes it is helpful to replace characters in the HID output
with something else (e.g. replace the non-printable FNC1 character,
that can't be sent via HID, with a semicolon).
To do this, mappings can be defined in the hid_character_mapping.txt file.
These mappings apply to all HID outputs.
The file hid_character_mapping.txt must be placed in the root directory of
the device, when connected via USB to your computer.
In the file one mapping can be defined per line.
The mapping must be in the form "from=to".
from and to are ASCII codes in decimal format.
Any lines starting with # are treated as comments and are ignored.
Example:
# Mapping of characters in HID outputs
# Map FNC1 (ASCII 29) to semicolon (ASCII 59)
29=59
