1. Function description
    This routine shows how to create an I2C device to read and write operation EEPROM on RT_Thread system

2. Use environment
    Hardware environment: development hardware platform corresponding to the project 
    Development board:      N32G457QEL_EVB V1.1

3. Instructions for use
    Describe the configuration method of related modules; for example: clock, I/O, etc. 
        1. SystemClock: 144MHz
        2. GPIO: LED:D17--PB15
                     I2C1: I2C_SCL--PB8I2C_SDA--PB9
                     Log: TX--PA9 RX--PA10 Baud rate: 115200

    Describe the test steps and phenomena of Demo 
        1. After compiling, download the program to reset and run;
        2. This routine creates two threads in main(), test0 thread and test1 thread, test0 thread is used to control D17 250ms flashing, 
            test1 thread is used to test I2C device read and write operation EEPROM, test results are printed out through the serial port
