Hi all, Thanks for ur support in the fb driver issue on the EDB9312 type board. I have worked on the fb driver and figured it out. I am working on the touch driver right now. Touch driver does work, but calibration problem persists. My relevant device specifications:- EDB9312 running Frame Buffer driver Touch driver There is NO X11 on the Device running. I am testing the touch driver through Qt/Embedded Applications. I am getting the interrupt, but the problem is I am unable to get the correlation between the display driver, mouse click and the touch driver. I don't know the reason. I think we need to run calibration program. How do I produce the appropriate X, Y, values? I think the values of Z1, Z2 are appropriate as I am seeing the valid values. Is the Calibration program a must to handle this? Can't we handle this in the driver level? Can some one briefly explain me how the touch driver communicates with the display driver? I have registered my touch driver through misc_register() call. Regards, Mukund jampala -- Kernelnewbies: Help each other learn about the Linux kernel.
