Report Using differential example: only first diff is correct in ADS1115 16-bit A/D converter (Texas Instruments) Posted October 17, 2013 Hey, I am testing your library, loving the debug options. After doing some copying and trying, I have hooked up the ADS1115 (adafruit breakout) to a Mega and a calibrator. Using your example code for the differentiator, I notice that only the first sample, right after the initialisation, is correct. All others have a tiny count. Any idea how to attack this?
