2.1.2.3 Communication With the System CPU Application

The Sensor Controller tasks and System CPU application exchange data through shared memory in the AUX RAM. Sensor Controller Studio generates type definitions and other needed definitions for easy access to these variables.

A pair of event signals is used by the Sensor Controller Interface driver to control the Sensor Controller tasks:

  • To Sensor Controller: CTRL initiates a control operation that starts or stops Sensor Controller tasks.
  • From Sensor Controller: READY indicates that the control interface is idle and ready for another control operation.

Another pair of event signals is used by the Sensor Controller to notify the System CPU and exchange data:

  • From Sensor Controller: ALERT wakes up the System CPU if currently in standby mode, and generates a callback (interrupt).
  • To Sensor Controller: ACK indicates that the System CPU has handled the last alert and is ready for another.

The event signaling is handled internally by the Sensor Controller Interface driver and the Sensor Controller firmware framework, but it is exposed to the application through function calls and callbacks.
