This project is I've attached the product datasheet for reference. The task is ill-defined enough that you typically need to either build a custom translator as an MCU firmware, or else have one of your existing ends be willing to talk the foreign protocol as encapsulated by an intermediary translator, which can at times be extremely awkward, especially if latency vs stall limits means you end up having to proactively cache responses to likely I2C read requests over serial. That looks like it can be used as I2C interface provided that the software implements the I2C signal generation and knows how to talk to specific I2C devices. using the generic commands above for each few bytes. 1. 3 Separate I2C Buses; I2C, SPI & Dallas 1-Wire interfaces; Simple ASCII protocol is easy to use with any OS, and any programming language.
