Subject: how test keypad driver in 2.6.10
Date: Tue, 14 Feb 2006 10:51:11 +0530	[thread overview]
Message-ID: <417f1b740602132121q3d9c19a8r6d5c3d8b042991ac@mail.gmail.com> (raw)

Hi,
I need to test a keypad driver in 2.6.10. For that, to write a simple
application to read the device file and write it to display, dont I
need node to be in "/dev " ?.  But I agree, in 2.6, concept has been
changed. When I do

# cat /proc/bus/input/devices

I get

I: Bus=0019 Vendor=0001 Product=0001 Version=0100
N: Name="KBD"
P: Phys=
H: Handlers=kbd
B: EV=3
B: KEY=800 1681 0 38a14001 50004ffc

Ive gone through "Using the Input Subsystem", By Brad Hards, published
in Linux Journal. link: http://www.linuxjournal.com/article/6429
How to use Handlers ??

dev fs entry is not created. But sys fs entry
/sys/devices/platform/keypad/driver/keypad/driver/keypad/..... goes
indefinitely. same is with
/sys/bus/platform/devices/keypad/driver/keypad/driver/..........

but couldnt find how to get a way to access kbd from user space.
Can any one have example ??

Please anyone, help me.
regards,
--pramod
