1. Function description

    This test example demonstrates the basic communication between UARTy and UARTz by querying and detecting identifications in half-duplex mode.
    First, UARTy sends TxBuffer1 data to UARTz, and UARTz receives data and stores it in RxBuffer2.
    Subsequently, UARTz sends TxBuffer2 data to UARTy, and UARTy receives data to RxBuffer1.
    Finally, compare the two groups of received data and sent data respectively, and store the comparison results in the TransferStatus1 variable and the TransferStatus2 variable.
    UARTy and UARTz can be UART1 and UART2.


2. Use environment

	Software development environment: KEIL MDK-ARM V5.34.0.0
    Hardware development environment:
         N32G05x series:
            Developed based on the evaluation board N32G05xRBQ7_STB V1.0
         N32G05x series:
            Developed based on the evaluation board N32G05xRBL7_STB V1.0


3. Instructions for use

    The system clock configuration is as follows:
    -System clock = 64MHz
    
    The UART configuration is as follows:
    -Baud rate = 115200 baud
    -Word length = 8 data bits
    -1 stop bit
    -Verification control disabled
    -Receiver and transmitter enable
    -Half-duplex mode enabled
    
    The UART pin connections are as follows:
    -UART1_Tx.PB10 <-------> UART2_Tx.PB4

    
    Test steps and phenomena:
    -After the Demo is compiled in the KEIL environment, download it to the MCU
    -After resetting the operation, check the variables TransferStatus1 and TransferStatus2 in turn, among them,
      PASSED means the test passed, FAILED means the test is abnormal
