Sample Description

|
|
================================================================================
|
|
|
功能描述：
|
|
|
此样例演示了I2C通过轮询方式进行通讯，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 polling. 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

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_Polling
|
|
|
从机程序为I2C_TwoBoard_CommunicationSlave_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_Polling
|
|
|
Slave program: I2C_TwoBoard_CommunicationSlave_IT
|
|
|
To modify the speed, simply modify the I2C_SPEEDCLOCK.
