Abstract
An electrical signal pathway compatibility is negotiated between a first reconfigurable circuit module and a second, connected, reconfigurable circuit module. The first reconfigurable circuit module includes a circuit board, a programmable device possessing a plurality of programmable input/output pins, a connector, a plurality of electrical signal pathways, a first embedded controller, whereby the plurality of electrical signal pathways and the connector constitute a first pinout, and a second reconfigurable circuit module. The second reconfigurable circuit module includes a second embedded controller and a second pinout. A request for configuration signal is transmitted from the first embedded controller to the second embedded controller. A compatibility analysis is performed between the first pinout and the second pinout using said second embedded controller. An approval signal is transmitted from the second embedded controller to the first embedded controller. The programmable device is programmed to configure the first pinout.
