Introduction
This driver is intented to control FPGA IPs connected to numerous hardware keyboards like:
- PS/2
- Home made matrix keyboards
The driver is currently named apf9328ps2 but this will be changed soon (or later ;-) ) to reflect its generic capability. Indeed all specific logic is done in the FPGA IP and the exported interface can be standardized.
Installation
Now installed by default for APF9328 rootfs (since armadeus-3.0). Not supported on APF27 yet.
Usage
# modprobe apf9328ps2 input: AT Raw Set 2 keyboard as /class/input/input0 Armadeus PS/2: APF9328KBD AT adapter OK!
- If you have a graphical LCD connected to your board (= virtual terminal), then you should see what you type.
- If you don't have any virtual terminal, but only the serial console, you can do a quick test with:
# cat /dev/input/event0
Then you should see weirds characters when pressing the keyboard keys:
�,~~_�,}�}�3T,QToT6,TT�,�;��, � �
Keymap
- To change keyboard keymap (by default qwerty one):
# loadkmap < /etc/i18n/fr.kmap
