I trying to replace a control screen for my model railway with an Elecrow 7" display in an Arduino environment.
I have all screens laid out with image buttons and screen images.
I have exported the c and header files.
I would like to know if I add 5 800x480 images to a screen, how I can switch between them at runtime without affecting the buttons and how that can be done.
If I were able to find how the coordinates are pass from SquareLine to the Arduino project without having other files deleted I might be able to work it myself.
Hi, Richard’s solution is a good one. However, you can achieve the same result directly in SquareLine Studio by adding “Modify Flag” events to your buttons, which will toggle the “Hidden” flag on the images.
It seems however that I have beaten the gun. At his point of time, I can’t even get the basic images to load off the SD card.
Turning the logging on in LVGL I get hundreds of line of warning, that image can’t be loaded at a line in the lvgl code that is the brace at the end of a for statement.
There is no hint as to why.
The file system (FD) is mounted because it does report some stats.
What is wrong after that, I have not been able to work out.
I have reduced the UI to a single screen with a single image for now and hope that I might find an example somewhere that is similar so I can compare it with my sketch and find out what I have missed in setting up the file system and display image decoder, (PNG) and get it working.
The images were converted using the LVGL online converter.
After that, I need to work out how to change screens by finger swipe rather than button press. That will remove 26 widget image buttons.
