Hi averyone, I've been stuck on this for a while and It's time to call for help. I'm on a STM32H747IIT6 and I'm trying to have the M7 to handle Slint and the screen, while my M4 will be reading data from CAN and various buttons. My problem is that I don't know how to put those data on the screen. I know How to get them on the M7, but once I start the drawing loop (from the template app_window->run() ), how do I constantly update them? |

You got the Slint hello world running on the screen driven from the M7, right? And you're wondering how to read the data from the M4 while the event loop is running? That's a good question and we would need to add some example about that. And the thing is that I even don't know the answer. I was about to say to use So your best option right now is to add a timer with slint::Timer and poll from data from the memory in the timer handler. |

slint::invoke_from_event_loopfrom an interrupt, but i realize that this feature is not implemented for our STM32 platform backend.So your best option right now is to add a timer with slint::Timer and poll from data from the memory in the timer handler.
