BQ76952: IIC通信不成功

您好，推荐您使用100khz的通讯频率。

What are their communication settings? For frequencies higher than 100-kHz they should use the I2C Fast. For frequencies below or at 100-kHz, they should use normal I2C.This is changed in DataMemory>Settings>Comm Type. There is a description of these in Table 9-1. Comm Type Data Memory Settings of the Technical Reference Manual.

Additionally, the timing requirements are listed in Section 7.27 Timing Requirements - I2C Interface, 100kHz Mode and Section 7.28 Timing Requirements - I2C Interface, 400kHz Mode of the datasheet. They must make sure that they meet these requirements.
