DWIN 7″ Display Arduino Demo

I have a 7-inch DWIN HMI panel connected to an Arduino Mega and I need a compact sketch that proves the screen, the touch interface and basic UI widgets all work together.

Here is what I expect from the demo:

• On power-up the display shows two on-screen buttons and one editable text field. • A single tap (no swipe or pinch gestures required) should toggle each button’s colour and send a matching command back to the Arduino over serial. • When I tap inside the text field the on-screen keypad pops up, I can enter characters, and the final value is echoed to the serial monitor so I can verify what the display sent. • All resources

• the.hmi project for DGUS Studio / TA, the Arduino IDE sketch, and any custom fonts or images
• are included and clearly commented so I can extend them later.

If you are familiar with DGUS / Smart Screen toolchains and have already driven a DWIN screen from an Arduino Mega this should be a quick turnaround job. Once I can compile, upload, and see the buttons and text field responding exactly as described I will mark the project complete.
