The ADuC812 MicroConverter is an Analog Devices IEEE 1451.2 compatible smart transducer interface
This document outlines how to implement a true minimal IEEE 1451.2 standard interface on the Analog Devices ADuC812 MicroConverter. It details the creation of modular, scalable code for developing a Smart Transducer Interface Module (STIM) that can be modified to meet end-user requirements.
The guide explains the software architecture required to map the IEEE 1451.2 standard blocks onto the hardware features of the ADuC812, including its 8051 compatible MCU, flash memory, ADCs, and SPI port. It provides an overview of the necessary software modules for handling transducer data, status registers, and communication protocols.

It is used as an IEEE 1451.2 compatible Smart Transducer Interface Module (STIM).
A Smart Transducer Interface Module that ranges in complexity from a single-channel sensor to many channels and communicates via a digital interface.
The Transducer Independent Interface, which is simply a 10-wire serial I/O bus.
The implementation consists of four modules: STIM block, TII block, TEDS block, and Address and Function block.
