SW35xx_lib

A platform‑agnostic I²C library for controlling SW35xx‑series charger ICs (SW3518, SW3520, etc.) from any microcontroller or host.

Features

• Read charging voltage and current
• Detect and negotiate fast‑charge protocols (QC, PD)
• Issue USB‑PD hard resets
• Set custom current limits
• Pluggable I²C bus interface for maximum portability

Requirements

• C++11 (or later) compiler
• SW35xx‑series hardware wired to your platform’s I²C pins
