The ADC to I2C subsystem example demonstrates how to use the internal ADC to convert an analog signal into a digital representation and transfer the result through I2C. The example configures the MCU to act as an external ADC, receive I2C commands from an I2C controller, and execute the received command accordingly. With simple example commands provided, users can utilize the framework to implement their own commands. Optionally, the MCU can also process the ADC data before transmitting the data via I2C, which is especially useful in applications that need to process the raw data into meaningful values. Download the code for the ADC to I2C Subsystem here.
The following figure shows a block diagram of the system.
The application requires the internal ADC and 1 instance of the I2C.
