View source for Linux driver for FPGA controlled keyboards

== PAGE UNDER CONSTRUCTION !!! ==

==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 to reflect its generic capability. Indeed all specific logic is done in FPGA IP.

==Installation==
If not already done in standard Armadeus rootfs:
 $ make linux-menuconfig
 Device Drivers  ---> Input device support  ---> [*]   Keyboards  ---> <*>   AT keyboard
then
 Device Drivers  ---> Armadeus specific drivers  ---> <M>   Armadeus PS/2 driver

Reflash rootfs then:
 # modprobe apf9328ps2
 input: AT Raw Set 2 keyboard as /class/input/input0
 Armadeus PS/2: APF9328KBD AT adapter OK!

==Test==
* 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:
 # cat /sys/class/input/input0/event0/dev
 13:64
If corresponding device node in /dev/input/ is not existing, then:
 # mkdir -p /dev/input
 # mknod /dev/input/event0 c 13 64

 # cat /dev/input/event0
Then you should see weirds characters when pressing keyboard keys:
 �,~~_�,}�}�3T,QToT6,TT�,�;��, � �

==Usage==
