                                样例使用说明
                             Sample Description
================================================================================
功能描述：
此样例演示了I2C通过中断方式进行通讯，主机先向从机发送15byte数据，然后再接收从机
发送的15byte数据,主机、从机接收数据成功后，主机和从机板上的小灯处于“常亮”状态。

Function descriptions:
This sample demonstrates communication between I2C devices using interrupts. 
The master device sends 15 bytes of data to the slave device and then receives 
15 bytes of data from the slave. After successful data transmission and 
reception between the master and slave, the LEDs on both boards remain 
constantly lit.
================================================================================
测试环境：
测试用板：PY32F403_STK
MDK版本： 5.28
IAR版本： 9.20
GCC版本：GNU Arm Embedded Toolchain 10.3-2021.10

Test environment:
Test board: PY32F403_STK
MDK Version: 5.28
IAR Version: 9.20
GCC Version: GNU Arm Embedded Toolchain 10.3-2021.10
================================================================================
使用步骤：
1. 编译下载程序到MCU，并运行；
2. 先复位从机，然后再复位主机
3. 复位完成后，按下主机user按键，主从开始通讯
4. 观察主从机的LED灯，当主机和从机LED灯由常暗转为常亮状态，则表明主机、从机收发数
据成功；当主机或从机LED灯处于闪烁状态，则表明主机、从机收发数据失败。

Example execution steps:
1.Compile and download the program to the MCU and run it.
2.Reset the slave device first, then reset the master device.
3.After the reset is complete, press the user button on the master device to 
initiate communication between the master and slave.
4.Observe the LEDs on the master and slave boards. When the LEDs on both the 
master and slave boards transition from being constantly dim to constantly lit, 
it indicates successful data transmission and reception between the master and 
slave. If the LEDs on the master or slave board are blinking, it indicates data 
transmission or reception failure.

注意事项：
PB6  -------> I2C1_SCL
PB7  -------> I2C1_SDA
主机程序为I2C_TwoBoard_CommunicationMaster_DualAddr_IT
从机程序为I2C_TwoBoard_CommunicationSlave_DualAddr_IT
如需修改速率，直接修改I2C_SPEEDCLOCK即可

Notes:
PB6  -------> I2C1_SCL
PB7  -------> I2C1_SDA
Master program: I2C_TwoBoard_CommunicationMaster_DualAddr_IT
Slave program: I2C_TwoBoard_CommunicationSlave_DualAddr_IT
To modify the speed, simply modify the I2C_SPEEDCLOCK.
