Initialize the MBX master object for RTU and pass various configuration parameters to initialize this _MBX_MASTER type master object.

Parameters

• MBxMaster: Pointer to the master object to be initialized.
• MBxSend: A function pointer for the data sending port.
• MBxGetc: A function pointer for the data receiving port.
• BaudRate: The baud rate of the actual serial link, used to automatically calculate the time for 1.5 characters and 3.5 characters.
• RxBuffer: Pointer to a memory space for storing received data.
• RxBufferSize: Total length of the memory space for storing received data. This memory space determines the maximum length of a single slave response that can be parsed.
• TxBuffer: Pointer to a memory space for storing data to be sent.
• TxBufferSize: Total length of the memory space for storing data to be sent. This memory space determines the maximum length of a single master request that can be sent.

Return Value

• MBX_API_RETURN_DEFAULT(0x00): Normal return.
• MBX_API_RETURN_ERR_PARAM(0x02): Parameter error, check the parameters passed during the call.
