**Home-Centered Navigation**
The Home screen is the center of a four-way navigation layout. **Clock**, **SD Card Files**, **Apps Menu**, and **Settings** are positioned above, below, left, and right of Home. Swipe up, down, left, or right on the touchscreen, or use the five-way joystick to quickly navigate between screens.
The `ui_sd_null` and `ui_sd_on` icons switch automatically to indicate the current SD card status. The battery indicator in the top-right corner shows the current charge level using an `XX/100` value and a five-bar gauge, with each bar representing **20%**. The navigation indicator in the bottom-left corner shows your current position within the four-way navigation layout.

# Clock
The main Clock & Calendar screen is powered by a dedicated **PCF8563 real-time clock (RTC)**, which keeps time even when the device is powered off. The **day of the week** is shown in the top-left corner using the **SUN–SAT** abbreviations, while the date is displayed in **MM/DD/YYYY** format. The current time is centered below in a large **60 pt** display using the **HH:MM:SS** format.
**Double-tap the screen** to enter manual time and date settings. Changes take effect immediately after adjustment.

# **SD Card files**
The SD card file system supports hierarchical navigation through multiple levels of directories. The header dynamically displays the current path: **SD Card Files** is shown at the root, while entering a subdirectory updates the title to **SD / Current Path**.
The file list uses distinct icons to identify folders and files, with the scroll indicator appearing automatically when additional content is available. Tap a folder to open its contents, or press **B** to return to the previous directory. From the root directory, press **B** or swipe down to return to **Home**. When no SD card is detected or the current directory is empty, a placeholder message is displayed automatically.

# **Apps Menu**
> \*\*Vertically Scrollable Icon Grid Launcher\*\*
The Apps Menu uses a three-column icon grid layout with vertical scrolling. Swipe up or down on the touchscreen to browse the available apps, then tap an icon to navigate and select an app.
The Apps Menu uses a fixed three-column icon grid with vertical scrolling. The column positions are **X = 35 / 125 / 215**, with the first row starting at **Y = 30** and a **105 px** row spacing, allowing six app icons to be visible across two rows.
Each app entry consists of a **70 × 70 px circular button** with a **35 px radius**, with a centered name label positioned directly below it. The button uses `#BEE700` as its default background and displays a glowing outer outline in `#9DDE00` when pressed.
All icons and labels are contained within a **full-screen transparent vertical scrolling container** sized **320 × 240 px**, with no background or border. The underlying background and navigation icon along the left edge remain visible through the container.
**Swipe left** on the touchscreen to return to **Home**.

# Settings
**Settings** brings volume, brightness, Wi-Fi, and system shortcuts together in one place.
Use the two vertical sliders on the left to adjust the volume and screen brightness. Changes take effect immediately and are saved to NVS.
The Wi-Fi status panel in the top-right refreshes every 2 seconds. When connected, it scrolls through **“connect: SSID”**. Tap the panel to open Wi-Fi setup.
The **2×2 shortcut grid** provides quick access to **Advanced Settings, USB MSC, Bluetooth,** and **System Info**.
**Swipe right to return to Home.**
