AN-1150 Auto-ranging I2C Capacitance Meter
This application note has demonstrated how to configure a GreenPAK5 mixed signal IC to build an auto-ranging capacitance meter. This frees several of the microcontroller’s resources, including several GPIO pins, a counter, a timer, compute cycles, and possibly some interrupt routines. It makes capacitance measurement as simple as reading values over an I2C bus.
