This section describes how to develop sensor applications and drivers using the Qualcomm® sensing hub (QSH) framework. Follow the client APIs track if you are building an application on the application processor. Follow the sensor APIs track if you are writing a sensor driver or algorithm on the low-power processor.

Software for application and low-power processors

Directory layout for the application processor source tree (sensing-hub/) and the low-power processor application digital signal processor (aDSP) framework.

Develop with client APIs

For application developers on the application processor. Covers the QSH client API session workflow and the SessionClient sample application.

Develop with sensor APIs

For driver and algorithm authors on the low-power processor. Covers the sensor and sensor instance lifecycle, QSH services, and stress testing with see_workhorse.
