Input Driver for USB-based ELO Touchscreens
Howdy Folks: I have recently written an input driver for XFree86 4.3.x for the USB-based touchscreens made by ELO Graphics (2500U-series controllers). At present, I have successfully tested the driver on several systems using Linux with XFree86 4.3.0. The sources can be found here: ftp://ftp.salemradiolabs.com/pub/srlabs/eloinput/ I have a couple of questions on how to proceed that perhaps some of the more knowledgeable folks who hang out here could help me with: 1) LINUX DEPENDENCIES The driver depends upon the Linux USB HID layer for proper operation. What is the proper way to include system specific headers (just 'linux/input.h', really) without breaking other platforms? 2) BUILD SYSTEM At present, I am getting the driver to build by putting it into a 'programs/Xserver/hw/xfree86/input/eloinput/' directory and then simply adding an 'eloinput' to the 'SUBDIRS =' line in 'programs/Xserver/hw/xfree86/input/ Imakefile'. This is clearly incorrect, but I am not enough of an Imake expert (a complete beginner, in fact) to be able to find the 'correct' location. Where should this go? Any help would be appreciated. For those interested, I have also written a small touchscreen calibration utility (requires Qt 3.x). This utility has been successfully tested with both serial (2500S controller) and USB (2500U controller) ELO models.
