The C3 board is a great asset for the University of Alberta’s ECE department, as it gives students and faculty an all-in-one credit card computer to use as a tool for learning. However, the C3 board lacks a file system, and a native file text editor. To give the C3 board capabilities more reminiscent of a general-purpose computer such as file-handling operations and file editing ability, the SD File System project and Screen File Editor project are proposed, designed, developed, and tested as prototypes.
