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.)

蜂鸣器奏乐刘德华《练习》，根据不同的单片机可以调整延时。8952单片机不能执行程序，但将数组的xdata改为code可以演奏一小段。需要高级一点的单片机。在不同的开发板上运行的效果有差异。(Buzzer music to Andy, " practicing" , depending on the chip can be adjusted delay. 8952 microcontroller can execute the program, but will be replaced by code xdata array can play short. Require senior point microcontrollers. The development board running at different effects are different.)
