My customer is getting a different address in their setup, please see details below.
I believe that I have found a mistake in your documentation for the ADS1219. It involves setting the slave address, when setting the address SCL to A0 and SDA to A1 I get the reverse setup. With the setup that I described, I was expecting an address of Hex 4b. However I got an address of hex 4e which is a physical setup of SCL to A1 and SDA to A0 according to your document (document ADS1219 SBAS924A –JULY 2018–REVISED NOVEMBER 2018)
