Input: create a book with Linux Input documentation
Now that all files under Documentation/input follows the ReST markup
language, rename them to *.rst and create a book for the Linux Input
subsystem.

Note that it is *not* suitable for other devices based on the -focaltec ft5x06 devices, since they contain vendor-specific firmware. In -particular this driver is not suitable for the Nook tablet. - -It has been tested with the following devices: - * EP0350M06 - * EP0430M06 - * EP0570M06 - * EP0700M06 - -The driver allows configuration of the touch screen via a set of sysfs files: - -/sys/class/input/eventX/device/device/threshold: - allows setting the "click"-threshold in the range from 20 to 80. - -/sys/class/input/eventX/device/device/gain: - allows setting the sensitivity in the range from 0 to 31. Note that - lower values indicate higher sensitivity. - -/sys/class/input/eventX/device/device/offset: - allows setting the edge compensation in the range from 0 to 31. - -/sys/class/input/eventX/device/device/report_rate: - allows setting the report rate in the range from 3 to 14. - - -For debugging purposes the driver provides a few files in the debug -filesystem (if available in the kernel). In /sys/kernel/debug/edt_ft5x06 -you'll find the following files: - -num_x, num_y: - (readonly) contains the number of sensor fields in X- and - Y-direction. - -mode: - allows switching the sensor between "factory mode" and "operation - mode" by writing "1" or "0" to it. In factory mode (1) it is - possible to get the raw data from the sensor. Note that in factory - mode regular events don't get delivered and the options described - above are unavailable. - -raw_data: - contains num_x * num_y big endian 16 bit values describing the raw - values for each sensor field. Note that each read() call on this - files triggers a new readout. It is recommended to provide a buffer - big enough to contain num_x * num_y * 2 bytes. - -Note that reading raw_data gives a I/O error when the device is not in factory -mode. The same happens when reading/writing to the parameter files when the -device is not in regular operation mode. |
