A smart ignitor control system has communications output electronic circuitry and communications input electronic circuitry. The communications output electronic circuitry generates output serial clock, data, and handshaking signals for communication with a master ASIC that is adapted to communicate with a smart ignitor. The communications input electronic circuitry inputs data and handshaking signals from a master ASIC. Smart ignitors are in circuit communication with the master ASIC via an ignitor bus. Optionally, additional circuitry digitizes analog voltages and waveforms from the ignitor bus and transmits the digitized data to an electronic information processor.

DETAILED DESCRIPTION There is provided in accordance with one aspect of the smart ignitor control system comprising: (a) a communications output electronic circuitry that generates output serial clock, data, and handshaking signals for communication with a master ASIC that is adapted to communicate with a smart ignitor and (b) a communications input electronic circuitry that inputs data and handshaking signals from a master ASIC.
The communications output electronic circuitry may comprise: (i) data interface circuitry connecting an electronic information processor to a memory device; (ii) data interface circuitry for connecting a master ASIC to a memory device; and (iii) control circuitry controlling the functions of the interface circuitry and memory device.
The communications input electronic circuitry may comprise: (i) data interface circuitry connecting the electronic information processor to a memory device, (ii) data interface circuitry for connecting a master ASIC to the memory and (iii) control circuitry controlling the functions of the interface circuitry and memory device.
Optionally, an additional circuit is included that digitizes ignitor bus analog voltages and waveforms, stored the data in a memory device then uploaded to the electronic information processor.
The electronic information processor software then performs functions such as but not limited to decoding, analyzing, displaying, archiving, and linking the data in the second memory device to other components such as but not limited to a electronic information processor screen, hardware indicators, one or more database engines, internet gateways, neural network an d expert systems.
DISCUSSION OF THE PRIOR ART U.

Pat.
No.
5,957,988 teaches a control circuit for controlling power supplied to an ignitor element but the control circuit is hardware in a permanent configuration rather than being software that can be easily adapted to particular applications as in the present invention.
