基于TI的USB IC的PC 及解决方案
EV2300是一个基于USB的解决方案，可用于评估应用TI的芯片设计的用于测量PC机电池电量的电路。 EV2300通过USB电缆的连接，也从一个电池电量计电路的通信端口（SMBus或HDQ）接受输入。通过运行相应的PC软件，EV2300接口板允许用户评估电池电量测试电路。
技术描述:
EV2300 Controller
The EV2300 controller is a bq8012 running at 4 MHz. The controller firmware is stored in flash memory and is executed by the core at power-up after the boot ROM code verifies the integrity words.
The controller communicates with target device(s) through either:a 2-wire SMBus communication port,a 1-wire HDQ port, or a 2-wire E2PROM I2C port. The 2-wire SMBus communication port supports both SMBus and I2C protocols.
2.3 USB Interface (USB)
The interface board connects to a USB port(version 1.1)on a host computer and is powered from the port.All communication over the USB is proprietary and does not fit any USB-defined device classes.Therefore communication with the device requires a loader and driver from Texas Instruments.
