Description


EDT FocalTech FT5x06 I2C Touchscreen Driver unit

The EDT FocalTech FT5x06 I2C controllers are a range of capacitive touchscreen controllers that include multipoint touch support and are used by a variety of small LCD displays. The exact features and capability of each device can be found by checking the datasheets which can be obtained online.

This driver is compatible with the following devices:

 edt,edt-ft5206       (5 touch points)
 edt,edt-ft5306       (5 touch points)
 edt,edt-ft5406       (5 touch points)
 edt,edt-ft5506       (10 touch points)
 evervision,ev-ft5726 (10 touch points)
 focaltech,ft6236     (2 touch points)
