+# Rack System Status Display
|
|
|
+
|
|
|
+## Overview
|
|
|
+
|
|
|
+This project displays the active system status on a 1.28" round TFT LCD mounted on the front panel of a 19" rack enclosure.
|
|
|
+
|
|
|
+On startup, a custom logo is displayed for approximately 10 seconds. The display then changes to indicate whether **System A** or **System B** is currently selected.
|
|
|
+
|
|
|
+System selection is determined by the voltage level present on a dedicated ESP32-S2 GPIO input.

|
|
|
+
|
|
|
+### Display
|
|
|
+
|
|
|
+* 1.28" Round TFT LCD
|
|
|
+* 240 x 240 resolution
