How kI2C_TransferDefaultFlag works for I2C?

[cavinlong]

Hi,

This is the sample code of the i2c_polling_b2b_master.

I do not understand why to use the TransferDefaultFlag here,as it seems like it will send the start signal again and will have multiple starts here since the line 108 already sent a start signal.

What is the purpose of having the flags here as the parameter?

Hello, I reviewed the information about that example, in this case, this function is using one flag to determine if the communication continues or if this needs to be stopped.
