1. Introduction: The TMP1075N

In this tutorial, we will walk through the creation of a complete ChipLib specification for the Texas Instruments TMP1075N Digital Temperature Sensor.

The TMP1075N is a simple device with a good mix of enums, access types, reset values, and bit masks to give a short, but rich, tutorial.

By the end of this guide, you will understand how to translate a PDF datasheet into a clean, machine-readable YAML file that generates your driver code.

Device Overview​

The TMP1075N is a digital temperature sensor with an I2C interface. It is often used as a low-power, high-accuracy replacement for the industry-standard LM75.

Datasheet Reference

Throughout this tutorial, we will reference the official datasheet:

  • Part Number: TMP1075N
  • Document: SBOS854F

Key Specs to Model​

Before writing YAML, we identify the key characteristics we need to capture:

  • Interface: I2C and SMBus compatible.
  • Resolution: 12-bit data resolution.
  • Register Width: 16-bit (all registers are 2 bytes).
  • Endianness: Big Endian (MSB first).

In the next step, we will start our YAML file by defining these global properties.
