Hi,
We are using microwindows-0.89pre8 on our SA1110 based design. The LCD we use is an Alps greyscale LCD and touchscreen is UCB-1200.
The official touchscreen device the kernel ucb driver uses is /dev/touchscreen/ucb1x00. I am using Ads Graphics client mouse driver from Nano-X which uses /dev/ts but if I create a device /dev/ts c 190 34, it doesn't have a driver in the kernel, so if I echo anything to /dev/ts is says no such device. So what I did was to change the code in mou_ads.c. Instead of opening /dev/ts it opens /dev/touchscreen/ucb1x00.
So my query is, is this method correct? The problem I am facing is, that if I run nano-X demos and try to use my touchscreen, it shows some x, y, pressure values from the kernel driver end, but the events are not being generated.
Can somebody please help me on this.
Thanks in advance,
Regds.....Aradhana
