Abstract: A food processing device includes a base housing having an attachment receiver arranged to receive a food processing attachment that is configured to perform a food processing operation. The attachment receiver includes an electrical connector having a plurality of electrical contacts. The device includes a first processor having a plurality of ports where each port of the plurality of ports is in electrical communication with each of the plurality of electrical contacts. The first processor is configured to: i) receive an identification signal at a first port of the plurality of ports via the electrical connector from a second processor in the received food processing attachment to identify the received food processing attachment, and ii) when an identification signal is not received, monitor a voltage at each of the plurality of ports to identify the received food processing attachment.
