Welcome to the Proximity Switch wiki.

Contents

[edit] Introduction

This webpage describes the Priximity switch software development effort for OMAP4 platforms. The purpose is to provide information on the current status and features planned in the road map.

SHF7741 Proximity switch can detect a near and far events.

[edit] Features Supported

Proximity data: The device registers as an input device.

It reports the events that can be read from can be read from /dev/eventX.

The sensor reports the proximity events in the range of 30mm.


Enable : Allows enabling or disabling of the switch from sysfs.

   * Input Subsystem
         o This is a generic Linux framework for all input devices like keyboard, mouse, touchscreen and defines a standard set of events. It interfaces to user space through /sys/class/input interface. 
   * Evdev
         o Evdev provides a generic way for input device events to be accessible under /dev/input/eventX . 
   * Proximity Driver
         o This interfaces with SFH7741 accelerometer chip via GPIO. One GPIO line is used for generating interrupts while the other is used for switching on and off.
