单片机与bq34z100评估板 I2C通信,读取无应答

Other Parts Discussed in Thread: BQ34Z100, INA226

bq34z100评估板与EV2300通信正常,

与单片机模拟I2C通信时,发送数据,无读取应答。

*****************************************************************

读取一个字节的SoC,指令是0x02,程序流程如下:

开始I2C;发送(0xaa);读取应答;

发送(0x02);读取应答;

开始I2C;发送(0xab);读取应答;

读取数据;发送应答;

停止I2C;

以下是示波器截图,4张图是连续的,对应上面的程序流程
