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.

Clock

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

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.

The underlying background and navigation icon along the left edge remain visible through the container. Swipe left on the touchscreen to return to Home.
