EVE3 BT815 with STM32f446 some widgets not working in the Screen designer
Posted: Fri Jan 13, 2023 2:29 am
Hi
I am currently working on a Project with a custom PCB and the EVE3 Screen connected to it.
uC: STM32F4466RET6
Display: EVE3 BT815/816 4.3"
I'm using the EVE Screen Designer to generate the UI Code
Version: 4.8 RC2
as IDE I'm using the STM32 Cube IDE with CubeMX.
Version: 1.10.1
I got the C code working, and also managed to display some widgets etc, but the Problem I have, is that not every widget is displayable.
By not displayable I mean that its shwoing up in the Screen designer, but when I activate it in the C Code and run it on the HW, the screen doesn't display it, there is just nothing there (except the few widgets that are working)
How I add a widget in the Screen designer and activate it in the code so you can spot possible mistakes:
Screen designer:
- drag a Widget from "ESD Widgets" (f.e "ESD Fixed Point Label") into the .page file opened in ESD Screen designer
- rename it to Round_Speed_Test
- in the Project Folder add the Widget to one of the "Fixed Position"'s
- drag and set the Depth Sort of the Widget in a way that it's visible by the rendered preview (f.e now it shows 0.00000 in the middle at the bottom)
- Connect the "Float value" pin to a Variable (float) which was dragged into the Screen designer previously
- Save the file and let it generate the code
Cube IDE
- in the file "App_Generated.c" remove the "static" in "static App application;" because it throws an error if I leave the "static" there
- Activate the new widget by adding right below the existing one's (that already get displayed on the screen the right way), which is in a switch case structure to chose the right widgets
- compile and download the code to the STM32
Now my Question is, can anyone spot any mistake that could cause the widget not to be displayed?
I'm 100% sure that the code above and the Refreshing of the screen Code gets executed, I checked it via Debugging
Or does anyone have a explanation on how I should add widgets the right way?
Like some tutorial or something like that, maybe I'm activating the widget the wrong way, idk...
Thank you in advance for your answers
