The Problem

A $200 USB Adapter Held Hostage by Proprietary DLLs

Texas Instruments makes the EV2300—a USB-to-I2C adapter for talking to their battery management ICs. It’s the standard tool for the BQ76920/BQ76940 evaluation boards. Plug it in, fire up bqStudio (TI’s official GUI), read some registers, write some registers. Simple.
