Programmable universal io interface

摘要

A system is provided that includes a controller that is configured to enable communication between one or more sensors 12 and a processor 18. The controller includes a plurality of input-output (IO) ports 16 each configured to couple to the one or more sensors 12. Moreover, each of the IO ports 16 is configured to couple to a plurality of sensor types such that each IO port is configured to couple more than one sensor type. The controller also includes an interface configured to receive a selection of a selected mode from a plurality of modes each corresponding to a sensor type. Furthermore, the controller includes a switch block having a plurality of switches each configured to toggle a connection in the switch block according to the selected mode.
