How to access I2C in XPe ?

Posted: 01-09-2009, 10:21 AM
How to access the I2C devices on XPe ? In the hardware I have, the touch
screen controller connected in this fashion....


Windows OS --->LPC--->SMBus--->I2C---Touchscreen controller

Should I have to write a PCI driver ? Which I tried but the driver did
not report any PCI configuration. I got a NULL pointer for
stack->Parameters.StartDevice.AllocatedResources in the StartDevice().

What should I do ? Am i in the right direction of accessing the I2C device ?

Is this custom hardware, or hardware from a manufacturer? If the later, you
should ask them for their device driver.

This is a custom hardware on Intel's Atom processor. The touch screen is
from Texas Instruments, they have drivers only on WinCE and not on XPe.

Which one is this 'normal' XP driver ? I dont think XP has any
touchscreen driver (as specially over I2C).
