== Notes and version constraints ==<br />
* LCD display not showing after programming – use the latest 2.8-inch resistive touch LCD sample program<br />
* If the '30.Touch' demo fails: use the GT911 demo routines for the 7-inch capacitive touch LCD (GT911 version) or the 4.3-inch capacitive touch LCD (GT911 version)<br />
* Technical support available only during working hours (Mon–Fri, 9 AM–6 PM GMT+8); replies within 1–2 working days<br />
* No prices, stock levels, warranty or certifications are provided in the source – these details are missing<br />
* Version-sensitive steps: using the most recent demo code is recommended because older examples may not work<br />
