1、功能说明

    该测例演示了UARTy与UARTz间实现串行IrDA低功耗模式红外解码功能的基础通信。
    首先，UARTy发送TxBuffer1数据至UARTz，UARTz通过中断接收数据存至RxBuffer1。
    随后，比较接收数据与发送数据，比较结果存入TransferStatus变量。

4、注意事项



1. Function description

    This test example demonstrates the basic communication between UARTy and UARTz to realize the infrared 
    decoding function of serial IrDA low power consumption mode.
    First, UARTy sends TxBuffer1 data to UARTz, and UARTz receives data through interrupt and stores it in RxBuffer1.
    Subsequently, compare the received data with the sent data, and the result of the comparison is stored in the 
    TransferStatus variable.

2. Development environment

    Software development environment: KEIL MDK-ARM V5.34.0.0
                                      IAR EWARM 8.50.1
    Hardware development environment:
            Developed based on the evaluation board N32G033K8Q7-1_STB V1.0

3. How to use

    The system clock configuration is as follows:
    -System clock = 64MHz
    
    The UART configuration is as follows:
    -Baud rate = 600 baud
    -Word length = 8 data bits
    -1 stop bit
    -Verification control disabled
    -Receiver and transmitter enable
    -16 times oversampling
    -IrDA mode enable
    
    The UART pin connections are as follows:
    - UART1_Tx.PA2    <------->   IrDA Transmitter
    - UART2_Rx.PA0    <------->   IrDA Receiver
    
    - GPIO.PB4         <------->   38kHz carrier

    
    Test steps and phenomena:
    -Reset and run the MCU, check the variable TransferStatus, where PASSED means the test passed and FAILED means the test is abnormal
