Serial sequencers connected in parallel

A system for controlling:

• a first device having a first input for controlling the operation of the first device and having a first output indicating status of the first device, and
• a second device operating in conjunction with the first device and having a second input for controlling operation of the second device and having a second output indicating status of the second device;
• said system comprising:
• a signal conditioning circuit for generating digital signals corresponding to signals provided by the first and second outputs;
• and
• a digital signal processor for analyzing the digital signals and providing signals to the first and second inputs, said processor executing a software program implementing:
• a first serial sequencer for controlling the first device by evaluating the digital signals corresponding to the output signals of the first device, and by instructing the processor to generate an output supplied to the first input of the first device for controlling operation of the first device;
• and
• a second serial sequencer for controlling the second device by evaluating the digital signals corresponding to the output signals of the first and second devices, and by instructing the processor to generate an output supplied to the second input of the second device for controlling operation of the second device;
• and
• wherein said first and second serial sequencers operate simultaneously in parallel and independently of each other so that the first device is controlled by the first serial sequencer in response to the signals provided by the first output and the second device is controlled by the second serial sequencer in response to signals provided by the first and second outputs.
