An Arduino library to interface the Texas Instruments ADS1231 24-Bit ADCan analog-to-digital converter for weight scales. The ADS1231 is a 24-Bit80SPS, 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 ESP8266those 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 supplyover using the proper excitation voltageto the Seebeck effectand temperature compensation woes.
