Dear Vojtech,
I think that a 1:1 mapping between linux keycodes and what keyboard sends
is right, because the scan code to key code conversion is already
programmed and done inside the FPGA code.
And the FPGA code changes with different keyboards attached?
The original OpenCores keyboard controller is a 6 rows x 12 cols
keyboard controller that can be customized for other row/col sizes
modifiying Constants.vhd VHDL file, in which also the translation table
is defined, and for different key disposition schemes both the number of
rows and cols can be changed. We are currently using this controller
with a 4x4 key matrix, and with a different key mapping values, so I
thought that it would be preferable to have the driver mapping fixed to
1:1 and do the mapping in the VHDL, since in most cases the keyboard
using this controller would be different to the default keyboard defined
in the original Contants.vhd VHDL file.
Regards,
Javier
Best regards,

This looks utterly wrong: It assumes 1:1 mapping between Linux keycodes
and what the keyboard sends, which I can't believe is the case.
