SUZITI File System

The SUZITI File System is an implementation of the FAT32 file system for the Rasberry Pi (r/pi). We connect it with a small graphical display and 5 buttons to let a user navigate through the filesystem on the SD card of the r/pi, create files/directories and view/edit text and images; all with our own implementation of I2C and gorgeous UI!

Features:

• Custom FAT32 implementation for the r/pi
  • Read/write/delete/create/rename/truncate/duplicate files on the pi's SD card
  • Create and navigate directories
  • See fat32.o and main.c; any files starting with fat32
• Custom I2C communication protocol
  • Communicate between r/pi and graphical display
  • See bitbang-i2c.c
• Graphical display
  • Created driver for SSD1306 OLED display based on datasheet
  • Supports graphics primitives (pixels, shapes, text) and PBM image display
  • Added support to draw on PBM (image) files and save them to filesystem
  • See display.c, display.h
• UI design
  • Made interactive cursor system for drawing
  • Created animated welcome screen with bouncing folder icon
  • See main.c
• Button matrix
  • Designed and soldered buttons to communicate with r/pi via GPIO
• "Laptop" 3D print
  • Created custom CAD to hold display and buttons here

Use:

• Connect device to your laptop and run "make" in terminal inside the suziti-filesystem folder.

Team Contributions:

• Suze: Led fat32 implementation, file navigation, pbm/txt open & edit, UI + design
• Aditi: Led hardware design, i2c implementation, file and dir create/write/duplicate
• Together: Wrote display, built/soldered "laptop"
