This blog is to mention how to add the battery service and read the VDD through SAADC module. Also, the most important is to optimize the current consumption. SAADC (Successive approximation analog-to-digital converter) The SAADC is a differential successive approximation register (SAR) analog-to-digital converter. It supports up to eight external analog input channels, depending on … Continue reading How to Measure the Battery through SAADC module for Current Optimization
