Abstract: A system and approach for a programmable display. The system may incorporate a display designed to operate a combustion control mechanism, dedicated purpose devices having a status represented by a set of defined data items referred to as registers, programmable behavior logic designed by a customer, other registers created by the customer to provide data generated by the programmable behavior logic, and a standard interface for serving the other registers to the display. The standard interface may be a protocol used by a web server. The web server may receive requests for data from a client and provide responses to the requests from the client. The customer, by data from the programmable logic, may control content, appearance or behavior of one or more objects on the display. The objects may send altered values to registers for operating the combustion control mechanism.
