    JUNO_I2C_IO_TRANSFER(WriteMsg(0xFF, ptMyWriteBuff, sizeof(ptMyWriteBuff))), 1);
 
// OR, create an array of messages
JUNO_I2C_IO_MSG_T ptArrTransfer[] = JUNO_I2C_IO_TRANSFER(
    WriteMsg(0xFF, ptMyWriteBuff, sizeof(ptMyWriteBuff)),
    ReadMsg(0xFF, ptMyReadBuff, sizeof(ptMyReadBuff))
);
ptApi->Transfer(ptI2c, ptArrTransfer, sizeof(ptArrTransfer) / sizeof(ptArrTransfer[0]));

Parameters

ptI2c	I2C module instance.
ptArrMsgs	Pointer to message array created with JUNO_I2C_IO_TRANSFER(...).
