[参考译文] BQ27220：通过 cc2640通过 i2c 通信配置 bq27220电量监测计

请注意，本文内容源自机器翻译，可能存在语法或其它翻译错误，仅供参考。如需获取准确内容，请参阅链接中的英语原文或自行翻译。

我正在尝试通过 i2c 接口通过 TI 的 CC2640 BLE 模块更新其参数。 我尝试使用 http://www.ti.com/general/docs/lit/getliterature.tsp?baseLiteratureNumber=sluubd4&fileType=pdf 中提供的示例代码进行编码 、但仍然无法更新电池的设计容量。 您能不能指导我如何配置电池电量监测计的参数。

我要添加尝试更改电池参数(设计容量)的代码。
