An Arduino library to interface the Texas Instruments ADS1231 24-Bit ADC, an analog-to-digital converter for weight scales. The ADS1231 is a 24-Bit, 80SPS, 1-channel delta-sigma ADC for resistive bridge sensors & weight scales.

- Atmel SAM
- Espressif ESP8266
You probably do not want to use this library. Have a look at the ThomasRyanDavies/ADS1231 Arduino library by Thomas Ryan Davies and other libraries for the ADS1231 instead.
This library has been sourced from the Arduino Forum.

Thank you!
For compatibility with ESP8266, those compile-time errors have been fixed.
- error: 'SREG' was not declared in this scope
- error: cannot convert 'volatile uint32_t*' to 'volatile uint8_t*'
You should consider getting into the details of strain-gauge load cell sensors when expecting reasonable results from your measurements. The range of topics is broad, starting with a sufficient and stable power supply, over using the proper excitation voltage, to the Seebeck effect, and temperature compensation woes.
