EEZ Studio loop works in simulation but not on ESP32 hardware

[ibrahimkhalil2000hamid-debug]

Hello community,

I'm facing an issue with an EEZ Studio project. I've implemented a loop that should:

Increase a needle value to 80 when a start button is pressed

Then decrease it back down

The simulation in EEZ Studio works perfectly. I can see the needle moving as expected on my PC. However, after exporting the code and uploading it to my ESP32 elecrow display, the start button press doesn't trigger any action. The needle remains static.

Has anyone encountered similar issues with EEZ Studio code generation for ESP32? Any suggestions on what might be causing this hardware/software mismatch?

Hardware: crowpanel elecrow 7 inch display
EEZ Studio version: 0.24.0

Most probably you forgot to call ui_tick(), see https://github.com/eez-open/studio/wiki/FAQ#how-to-integrate-with-my-existing-cc-project

Hey, thank you for your quick anwer... I actually have this in my loop.
void loop()
{
lv_timer_handler();
eez_flow_tick();
delay(5);
}
in ArduinoIDE after I upload the code to my esp32, I click the start button, but there ist no reaktion of it. Even though everything works perfectly in the Eez studio during the simulation, I just don't understand what I am supposed to do.

You should call ui_tick(), not eez_flow_tick().
