Hello, I am trying to read and write over I2C to a INA 226 Current sensor and I cannot get it to work. Every time, the function will return the
这是某个传感器规格书上的I2C协议,地址为0x44 若是我原来的想法,写寄存器,读寄存器如下 1 2 Sensor_Read_Byte(0x44,addr,&data_buf);传感器地址,寄存器地址,变量 Sensor_Write_Byte(0x44,addr,&data);传感器地址,寄存器地址,寄存器数值 可逻辑分析仪上是这样的 虽说我函数里填进去的数值为 01000100(0x44) 但...
