Toph What is it? Final project for ECE-UY 4144 Intro to Embedded Systems Design. A modular solution to wall sensing How? Miniflex contains the physical modules used in the Toph system. Toph is written in C using minimal Arduino-specific syntax and macros. Toph is extendable. New modules can be added with a single line of code. Why? An exercise in embedded design, from hardware to software.
