Langmuir Titan T25 GUI Modifications (Reverse engineered bendcontrol.jar).
I’ve started addressing several urgent issues within the Langmuir Titan T25 GUI, beginning with implementing dynamic scaling based on screen resolution and increasing the size of key buttons and text elements for better usability.
In the video you can see the early GUI scaling test, running on Windows 11 environment.
To understand the inner workings of the main application, I reverse-engineered and decompiled the .jar file with assistance from ChatGPT. This provided valuable insights into how the GUI handles layout rendering and event management.
The next step involves upgrading the onboard computer from Orange Pi 3 to Orange Pi 5 Pro. I’ve already completed the file migration, package installation, and successfully executed bendcontrol.jar. Since the Orange Pi 5 Pro uses a different kernel and boot structure, the original SD card image for the Pi 3 isn’t directly compatible.
This hardware upgrade enables the touchscreen to run at Full HD resolution, overcoming the Pi 3’s GPU bottleneck that previously limited the display to roughly 720p and caused sluggish performance. With the Orange Pi 5 Pro, these responsiveness and rendering issues are eliminated.
To clarify, I do not plan to release any source code, as it remains the proprietary property of Langmuir Systems. However, once the GUI modifications reach a stable state, I may consider releasing a recompiled version of the modified .jar file. There’s no defined timeline for completing these updates, as I intend to proceed carefully and ensure that every change is implemented correctly.
