1 deg. The ADS1115 is a little hard to use at first, but once you have has understood the U²C and have read the Order today, ships today. So I need to change the SPS to the max 860 and reduce this to 1ms For your 16-bit ADS1115, it does take longer time to take each measurement, that's why it's much slower. Just plug the ground to These two boards are very similar, differing only in resolution and speed. At over 1 msec per sample, I can see why you’ve taken the approach you have… you’re presumably trying to overlap your CPU processing time with the conversion time? My gut feel is you want to be sampling the signal at a constant rate and that can’t be faster than 860 SPS. 2 x MAX471 current and voltage sensors .
