Update GUI Model without RTOS inter-task messaging

[SPano.1]

Hi,

I need to update the GUI Model of touchGFX from another task that read data from some peripherals. I've seen that's recommended to use inter-task messaging system, like messaging queue, but unfortunately my RTOS doesn't implement anything like that yet.

What can I use to connect the Model class and other RTOS tasks?

Which OS are you using?

[SPano.1]

ERIKA3. I've contacted the developers and they said me that it doesn't implement it yet, so I write a singleton class that could resolve my issue and act as a data queue for the Model GUI. Is there any "best practice" to use in situation like that?
