bq77910能否通过IIC与单片机通信,我只要读他的状态位,不写东西。不知道可不可以。如果可以,能否提供相关资料

WSX,
可以的,使用USB-TO-GPIO口的仿真器及相应的GUI软件,可以用PC来读取相应的参数及控制。

Trevor给你详细的描述了如何在PC机上基于TI提供的开发软件来进行通讯和配置。我补充一点BQ77910与单片机通讯时的资料,如果前期的设置工作按照trevor提供的工具和资料完成了,BQ77910也可以通过I2C与通用的单片机进行通讯,单片机可以对它进行读和写的操作(但开发过程中还是建议采用TI的GUI界面,这样更加直观和高效),请您参考datasheet page 38的操作时序

注意BQ77910的I2C与标准I2C的区别
The bq77910A communications protocol varies from the full I2C standard as follows:
• The bq77910A is always regarded as a slave.
• The bq77910A does not support the general code of the I2C specification.
• The bq77910A does not support address auto-increment, which allows continuous reading and writing.
• The bq77910A allows data to be written or read from the same location without re-sending the location
address.
