Field Documentation

uint16_t I2C_TransferSeq_TypeDef::len

Number of bytes in data to send or receive. Notice that when receiving data to this buffer, at least 1 byte must be received. Setting len to 0 in the receive case is considered a usage fault. Transmitting 0 bytes is legal, in which case only the address is transmitted after the start condition.
