Description
Description
This application note shows how to use the ADC featured in the tinyAVR® 2-devices to measure current and monitor battery charge. The underlying theory is discussed, and a demo application is presented. The demo shows an implementation of a simple circuit where various nodes are connected to the ADC to make measurements. Furthermore, when using MPLAB® Data Visualizer, the relevant data can be presented live.
