Hi all,
I have successfully ported a uclinux system in my XtremeDSP video
starter kit board. Mi next goal is to have a touchscreen in my system.
I have successfully used a driver to control the framebuffer so
the 'graphical' part is solved, I can see printk messages in my LCD
monitor.
My doubts are in the touch interface part. I have a Penmount touch
device which is connected to a RS232 port of my board which is 'ttyS1'
device(I have 2 RS232 ports). In 'Menuconfig', I activated the options
'Touchscreen Interface' and 'Penmount serial touchscreen'. What I have
now in my system is:
# ls sys/bus/serio/drivers/
atkbd penmountlpc psmouse serio_raw
# cat proc/bus/input/handlers
N: Number=0 Name=kbd
N: Number=1 Name=evdev Minor=64
N: Number=2 Name=tsdev Minor=128
However, nothing appears if I do 'ls sys/bus/serio/devices'.
There is no dev/input or dev/tsdev device either.
I don't know how to assing a device for my touchscreen. I think that
the goal is that the driver receives the data from 'ttyS1' device but
I don't know how to do this because I don't know too much about drivers.
Please, any help will be very appreciated.
Thank you very much in advance.
Kind regards,
Pablo Colodron
