SparkFun ADS1219 Arduino Library

Arduino Library for the SparkFun ADS1219 Qwiic 24-Bit ADC adds four channels of high-precision, 24-bit analog input to your project over I2C, featuring programmable gain and up to 16 unique addresses

This is an Arduino Library for the ADS1219 24-bit 4-channel ADC from TI. It allows you to fully configure the ADC. Examples are provided to show how to use: single-shot vs. continuous mode; the input multiplexer; gain; different sample rates; and alternate I2C addresses. You can read the ADC voltage in millivolts (compensated for gain) or as the raw signed value.

Note: this library needs the SparkFun Toolkit.
