FreeRTOS实验17-1 FreeRTOS内存管理实验
硬件资源:
1,DS0(连接在PA8)，DS1(连接在PD2上)
2,串口1(波特率:115200,PA9/PA10连接在板载USB转串口芯片CH340上面)
3,ALIENTEK 2.8/3.5/4.3寸LCD模块(仅支持MCU屏)
4,按键KEY0(PC5)/KEY1(PA15)/KEY_UP(PA0,也称之为WK_UP)
实验现象:
按下KEY_UP键申请内存，内存申请成功以后就可以使用了，按下KEY0键
就是使用申请到的内存。当内存使用完成以后就可以按KEY1键将内存
释放掉。(Hardware resources:
1, DS0 (connected to PA8), DS1 (connected to PD2)
2. Serial port 1 (baud rate: 115200, PA9/PA10 connected on board USB to serial chip CH340)
3, ALIENTEK 2.8/3.5/4.3 inch LCD module (only supporting MCU screen)
4. Keyboard KEY0 (PC5)/KEY1 (PA15)/KEY_UP (PA0, also known as WK_UP)
Experimental phenomena:
Press KEY_UP key to apply for memory, memory application can be used after success, press KEY0 key
That is to use the applied memory. When the use of memory is complete, you can press KEY1 to store the memory.
Release.)

某公司安装了电子门，要设计门禁系统：
公司的雇员可以凭借密码、胸卡或指纹进入公司
计算机根据雇员的验证方式对其身份进行验证
管理员在监控室可以通过按钮直接开启电子门
访客可以按门铃请求进入，由管理员为其放行
管理员可以为新职员设置密码
(A company to install an electronic gate, to design access control systems: the company' s employees can rely on passwords, badges or finger into the company computer, authentication of the employee to verify their identity can be an administrator in the control room directly through the button to open electronic gates that visitors can rang the doorbell of the request to enter an administrator can be released by the administrator of its staff to set a password for the new)
