Claims20
A versatile programmable electronic controller, comprising:
- a programmable microprocessor including a non-volatile programmable read only memory, a random access memory and a non-volatile electrically erasable programmable read only memory;
- a plurality of voltage-limited inputs connected with said microprocessor;
- a plurality of control switches connected with said microprocessor having predetermined functions that are programmed by said non-volatile programmable read only memory;
- a display device connected with said microprocessor;
- a plurality of microprocessor outputs;
- a power supply for said microprocessor and said display device;
