Units – ADC Unit Analog-to-Digital Converter



Description


ADC integrated with ADS1100 which is a fully differential, 16-bit, self-calibrating,delta-sigma A/D converter. It communicates through an I2C interface,which means you can collect AD data thru PortA on M5 core from this unit to enhence your A/D performance.

An ADC’s work is basically collecting continuous signals from nature like the sound, electromagnetic wave , then convert it into discrete digital signals to become processable data for the MCUs.

The I2C address is 0x48.
