I’m trying to replace the Adafruit 2.8" piTFT with the Adafruit piTFT 3.5" (because at age of 42 I have some problems with little displays… )
In my opinion, there are two basic tasks to do it:
The kernel/module driver given by Adafruit is different for the two displays (in other words, it is not sufficient to change the line regrading the module and the resolution/refresh-rate in /boot/config.txt). So, in order to use it, I think it could be necessary to follow the installation instructions reported in https://learn.adafruit.com/adafruit-pitft-3-dot-5-touch-screen-for-raspberry-pi/detailed-install.
I think I will try today.
The resizing of the GUI. I read in another post that the GUI is fixed size at 2.8" screen resolution.
So I would like to study the possibility to have an auto-resizing GUI, depending on the screen resolution. It is a very interesting for me. Some years ago I realized at work a GUI for a Windows console which was auto-resizing (many years ago… …now as project manager I abandoned the implementation phases)… so it could be a good rentrée!
I will advise you all about the progress (which can be also not so good… )
Bye bye Zynthianers!
