1. Function description
    1. SPI full duplex software NSS mode to send and receive data
2. Use environment
    Software development environment: KEIL MDK-ARM 5.30.0.0
    Hardware Environment: Developed based on N32G031CL-STB V1.0
3. Instructions for use
    System Configuration;
        1. SystemClock48MHz
        2. GPIOSPI1: SCK--PA5,   MISO--PA6,  MOSI--PA7
                       SPI2: SCK--PB13, MISO--PB14, MOSI--PB15
    Instructions:
        1. After compiling, download the program to reset and run;
        2. SPI1 is initialized as a master, sending data, SPI2 is initialized as a slave, receiving data, after the transmission is completed, 
           check the data, and check that the status of TransferStatus1 and TransferStatus2 is PASSED
           SPI2 is initialized as a master, sending data, SPI1 is initialized as a slave, receiving data, after the transmission is completed, 
           check the data, and check that the status of TransferStatus3 and TransferStatus4 is PASSED;
