Optimization of the addressing code of DS18X20 at measuring multiple temperatures

It is critical technology to encode the digital sensor DS18X20 that measure multiple temperatures with the 1-wire bus. By the source of DS18X20, decimal code are coded which instead the 6 bytes of serial number. It makes very simple to distinguish a multiplicity of sensors. Encoder is indispensable to realize the technology. The principle and circuit and programming of the technology attested by practice are collecting and hold true.
