[edit] Introduction

This webpage describes the Digital Compass software development effort, mainly its current status and features planned in the road map.

At present, Digital Compass is supported only on OMAP4 platforms which uses the HMC5843 sensor. It is designed for low field magnetic sensing with a digital interface .

[edit] List of Features Supported

[edit] Design

The sensor interacts with the OMAP using the I2C bus. It reports the sensor values through the input subsystem.

The driver registers itself using the standard input device.

[edit] Upstreaming Sensors - Points for discussion

There is resistance from the input subsystem maintainers also alternate subsystem is thought of. However Linus has some objections for having a new subsystem. There is a possibility that it be merged in the input tree.
