I2Cderived
I2Cderived is a descriptive term used in embedded systems to refer to a design approach in which a wide range of system signals and functionalities are derived from or controlled via devices on the I2C bus. It emphasizes using I2C as a backbone to expand I/O, aggregate data, or generate higher-level signals without expanding the microcontroller’s native pin count.
The concept relies on I2C-enabled peripherals such as GPIO expanders, analog-to-digital converters, digital-to-analog converters, sensor hubs,
Typical patterns include using I/O expanders to provide additional digital outputs or inputs, employing sensor hubs
Benefits include reduced pin requirements, scalable I/O, and streamlined wiring. Limitations involve added bus traffic, potential
