I2C Slave

Which structure member contains the number of bytes transferred at the end of a transaction?
->XferCount does not function in this manner.

Hello @bitwisesys,

If I understand you correctly, you mean:
uint16_t XferSize; /*!< I2C transfer size */, in the __I2C_HandleTypeDef struct.

Otherwise, could you be a little more specific?

With regards,

Hi, If I call a TX function and for some reason the receiver sends a NAK before everything is read, then TxComplete happens. How do I know how many characters are actually read?
