Description

Add a RIOT driver for the Texas Instruments ADS1115, a 16-bit I2C ADC with 4 input channels, programmable gain, and single-shot/continuous conversion modes.

This driver enables configuring the device and reading conversion results (raw and millivolt values) over I2C.

Features

• I2C communication and device check
• Configuration (MUX, PGA, mode, data rate, comparator)
• Single-shot conversion
• Raw value reading
• Conversion to millivolts
• (Optional) Support for other ADCs in the family (ADS1113 / ADS1114)

Motivation

The ADS1115 is a popular, low-power ADC used in many embedded applications. Native RIOT support will ease integration for sensor nodes and analog signal acquisition projects.
