It is about two ADS1219 connected to the same I2C Bus, when in single acquisition mode, the ADC is disturbing the I2C Communication, so it is impossible to poll the status.
The Addresses as wired are ADC1: A0=1, A1=0 and ADC2: A0=0, A1=0
The failure occurs after starting a single conversion and trying to read register 0x24 to get the
DRDY state.
What happens:
While converting the ADS1219 sporadically pulls the SDA low.
The Pull-Up resistors for SDA and SCL are 1k each, we tried 500Ohm and still had the same issue.
