Let's do 过程贴
本文将通过“系统框图、电路原理图、如何开启运行、主要参数情况、实现步骤”等方面记录开发过程中的硬件设计、软件调试、项目代码等。
流程图part
主程序流程图（方框图）
根据流程图我们首先要将所需模块进行初始化。以下是初始化部分代码：
从流程图中不难看出来，我们使用了继电器这一模块，其原因是正常的板载所能提供的输出电压最多为5V，而这并不能驱动12V的电机，于是我们采用了继电器去驱动电机。我们所使用的继电器为5VDC（5V直流电）驱动，通过继电器进而驱动电机的动作。
其模式更改采用窗口发送的方式：通过串口发送不同的字符串，当STM32F411接收到对应的字符串后，修改程序当前模式并执行对应的模式。下面是通过串口修改修改电流阈值的图片（PS：因为我这个插入视频和GIF我没做过）：
下面是所用到的窗口字符串：
定时器中断流程图（方框图）
将选择后的模式功能部分放入定时器中，可以积极响应模式的要求并快速运行的运行，以下是定时器的内部代码：

void Store_Clear(void)
{
for (uint16_t i = 1; i < STORE_COUNT; i ++) //循环STORE_COUNT次，除了第一个标志位
{
Store_Data[i] = 0x0000; //SRAM数组有效数据清0
}
Store_Save(); //保存数据到闪存
}总结
通过近一个月的学习和使用，完成了基础任务和进阶任务，同时我还收获颇丰：
定时器应用：掌握了STM32定时器的精确配置与中断处理
I2C通信：熟练使用I2C总线驱动多个外设（OLED+INA219）
保护机制设计：理解了工业级保护电路的设计思路
人机交互：实现了串口命令行接口，提升系统可操作性
