1. Function description

     This example demonstrates the use of I2C interrupts as a master to send and receive data.

2. Use environment

    Software development environment:
    IDE tool: KEIL MDK-ARM 5.34.0.0
    
     Hardware 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

     1. Main clock: 64MHz
     2. I2C1 configuration:
             SCL --> PB10
             SDA --> PB11
             CLOCK: 100KHz
            
    3. USART1 configuration:
             TX --> PA9
             RX --> PA10
             Baud rate: 115200
        

     4. Test steps and phenomena
         a, jumper wire to connect slave I2C1
         b, compile and download the code, reset and run
         c, view the print information from the serial port and verify the result

4. Matters needing attention
     SCL and SDA must be pulled up
