2.2 Digital Interface

As noted in Section 1, the BOOSTXL-ADS7142-Q1 interfaces with the PAMB, which in turn communicates with the computer over USB. The two devices on the booster pack that the PAMB communicates over I2C are the ADS7142-Q1 ADC and the EEPROM. The EEPROM comes preprogrammed with the information required to configure and initialize the BOOSTXL-ADS7142-Q1 platform. Once the hardware is initialized, the EEPROM is no longer used.
