Raspberry Pi with ADS1115

Post by mustardseries »

Hi

We are using the ADS1115 with the pi (with linux).

when testing with a pot the top number we seem to be receiving is 511.98 - which in our understanding is closer to 9 bit - any thoughts why this might be?

thanks

Are you wired single-ended or differential?
What is the resistance value of your pot?
What are you using for Vcc?
Have you measured the output of your pot with a voltmeter?
