Abstract

A digital network between active components or "buttons" atop an e-textile fabric must handle the inexact placement of wires in the fabric both for signal distribution and for power distribution. We approach the problem of signal distribution by making the pin logic of the buttons reconfigurable and by providing enough local state to allow an external agent to discover and to reconfigure the buttons into a working network. We describe a prototype system of a 2x2 array of FPGA-and-microcontroller buttons atop a fabric with 0.100"-pitch wiring including architecture decisions, circuits and software algorithms.
