ADC unit is an integrated ADS1100 device which is a fully differential, 16-bit, self-calibrating, delta-sigma A/D converter.
It communicates through the I2C interface, which means you can collect AD data through PortA on the M5Core device in order to enhance your A/D capabilities and performance.
The default I2C address is 0x48 unless changed manually.
