Azure Sphere - RTapp Use Case

sagacr2018

Hello Experts,

 

I am trying to understand practical use cases of RTApp vs High-Level App.

 

Use Case 1: A Device wants to communicate with Azure Cloud but wants to keep running a Display based on SPI. The application also Scans Button Matrix. So Could communication part should be on High-Level app and other on RTApp? or everything should be done at the High Level App?

 

Use Case 2: Device has an array of sensors (e.g. Temperature, Barometric).  Whenever sensor reading crosses some limit, an alert will be sent. The device will also initiate a buzzer (require Square Wave). what should be on RTApp or what on High-Level App ?

 

Just trying to understand where we should consider using RTApp in the real world?

  • Hi Rohit,

     

    The RTApps should be used anytime you need strict timing requirements.  The high level application will block one some calls, so trying to do real time work on the A7 will eventually have timing issues. 

     

    For your use case 1, you could scan the button matrix in the RTApp for faster, non-interrupted scans.

     

    For your use case 2, I would recommend driving the buzzer from the RTApp and do everything else form the high level application unless some of the other sensors require real time processing.

     

    I hope this helps,
