An [esp-idf](https://github.com/espressif/esp-idf) component for interfacing with the [NAU7802](https://www.nuvoton.com/resource-files/NAU7802%20Data%20Sheet%20V1.7.pdf) 24-bit ADC, especially as packaged on e.g. the [Adafruit NAU7802](https://www.adafruit.com/product/4538) and [SparkFun Qwiic Scale](https://www.sparkfun.com/products/15242).
