I have explained some issues in the comments, a summary is below:

1. RESETPIN needs to be TRUE so the board will work
2. buffenable if set to TRUE/FALSE, the output will be changed slightly !!! why
3. increasing the gain, reduces the output value slightly (i.e the error increase with higher gain)
4. single channels are not working (such as AIN0 & AIN_COM), diff channels are working fine

Hi, I can't use the library with Arduino Uno, I can compile the code only for Arduino Mega. Can pins for Arduino Uno be remapped? Thank you.

I have try to use digitalwrite to made this library work on my arm's arduino,but I failed.And I am nowbie in coding,plz add arm's edition.

If there is possibility it would be awesome to see a port of this library for ESP32.

See it in:

Hi, I am writing for a problem encountered in using this library for my ADS1256 with Arduino Uno. The setting for the SPS does not work correctly, I don't know if it is my mistake or a bug, but I have already redone the connections 3 times, and confirmed the operation with other libraries.
Even writing the value in the register does not respond correctly to the settings (adc.writeRegister (DRATE, ADS1256_DRATE_10SPS);). The values ​​obtained either remain fixed at 50SPS, or oscillate between 2000 and 3000, or are lower than the set value over 50%.
Below is the code I use to measure SPS over a period of time, working with other ADCs. Furthermore, the gain only seems to divide the result by it's value.

int count = 0; double sum = 0; unsigned long t0 = millis();

while (millis() - t0 < 1000) {
    adc.setChannel(0, -1);
    float y = adc.readCurrentChannel();
    sum += y;
    count++;
}

Serial.print(sum / count, 4);
Serial.print(" , SPS = ");
Serial.println(count);`

Thanks.
I apologize for the translator, I don't have much experience with English.
