@par Example Description

This example provides a basic communication between UART2TX and UART2RX using DMA capability.
First, the DMA transfers data from SrcBuf1 buffer to UART2 Transmit data register,
then this data is sent to UART2RX.
Data received by UART2 is transferred by DMA and stored in DstBuf1 then compared with
the send ones and the result of this comparison is stored in the "TransferStatus1" variable.

UART2 configured as follow:
    - BaudRate = 1200 baud
    - Word Length = 8 Bits
    - One Stop Bit
    - No parity
    - FIFO enable
    - Hardware flow control disabled (RTS and CTS signals)
    - Receive and transmit enabled


@par Directory contains:

    - main.c           Main program


@par Hardware and Software environment:

    - This example is intended to run on MDR1986VE3 eval board with MDR1986VE3 microcontroller.
    - Connect UART2 TX (PD13) pin (XP29.2) to UART2 TXD (PD14) pin (XP23.3).
    - HSE oscillator is used so it should be present.


@par How to use.

To launch the example, you must do the following:
    - Create a project and setup all project configurations.
    - Add main.c file.
    - Add the required files from "Libraries" folder:
        MDR32F9Qx_config.h
        MDR32F9Qx_port.c
        MDR32F9Qx_rst_clk.c
        MDR32F9Qx_uart.c
        MDR32F9Qx_dma.c
    - Edit the MDR32F9Qx_config.h to set appropriate run-time parameter checking level.
    - Compile and link together all .c files and load your image into the target board.
    - Run the example.
