取系统默认语言ID源码，例程程序调用API函数取系统默认语言ID。(Take the system default language ID source , routine program calls API function takes the system default language ID.)

串口发送数据，字符，12864接受并显示字符(Serial port to send data, the character, to accept and display the character 12864)

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: 通过按键KEY_UP可以控制定时器AutoReloadTimer_Handle的开启，这个是 周期定时器，一旦开启就会不断的运行，直到按下KEY1将其关闭。按下KEY0 可以打开定时器OneShotTimer_Handle，这是个单次定时器，只会运行一次， 运行周期到了以后就会停止运行，除非按下按键KEY0将其再次开启。(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: The timer AutoReloadTimer_Handle can be turned on by keying KEY_UP. This is The periodic timer will run continuously once it is turned on until KEY1 is pressed to turn it off. Press KEY0 You can turn on the timer OneShotTimer_Handle, which is a single timer and only runs once. The run cycle will stop after that unless KEY0 is pressed to turn it on again.)

温度仪表通用程序，可检测热电偶和CU50。程序带有PID控制算法和PID参数自整定算法。(General procedure can detect the temperature meter, thermocouple and CU50. The program with a PID control algorithm and the PID parameters self-tuning algorithm. )

读取ms5803传感器的各项数据，用串口将数据打印(Read the data of the ms5803 sensor and use the serial port to print the data)

开锁程序,可以通过DA1990a打开门的锁，并不需要注册钥匙。(Unlock procedure, you can open the door lock DA1990a is no need to register the key.)

说明：  STM32+RC522+充值+扣款+改密码+开锁(STM32 + rc522 + recharge + deduction + change password + unlock)

说明：  基于STM32平台下的FSMC外接SRAM的程序(Program of FSMC external SRAM based on STM32 platform)
