基于stm32f407的手写识别程序，亲测可用(Handwriting recognition program based on stm32f407)

说明：  cpu卡 读卡示例程序 单片机stm32 编译环境keil(CPU card reading sample program STM32 compiler environment KEIL)

说明：  针对两种flash所写的读写程序,公布我原来写的针对两种flash所写的读写程序，用的单片机是51系列！(against two flash reader written procedures, I was originally announced against two flash reader written procedures, the MCU is 51!)

温度显示仿真图，利用proutes软件仿真(Temperature display simulation map, use proutes software simulation)

89c51 单片机通过 PFC8591进行AD-DA转换。最后通过1602显示屏进行显示 (89C51 singlechip AD-DA conversion by PFC8591. To display the 1602 display)

温度控制器程序，包括PID算法，控制精度可达到0.01度，单片机采用宏晶公司的STC89C54(Temperature controller procedures, including the PID algorithm, the control precision can reach 0.01 degrees, the SCM' s STC89C54 Wang Jing)

名称：门禁模拟 模拟现实中门禁系统，可以输入密码进入也可以呼叫住户，再由住户按下开门按键 实现改密码功能，密码保存在24c02中能保证掉电不丢失密码。八个LED灯分别代表 8家住户，其中开门按键为共用，还带有忘记密码恢复按钮，模拟恢复出厂设置， 显示部分为LCD1602。程序共分为3种模式，分别为 等待输入 密码修改 呼叫住户 3种模式，其中等待输入是主要状态，所以在进入密码修改 呼叫住户模式后如果 长时间没有操作能自己切换到等待输入模式。(Name: Access Analog Simulating real access control system, you can also enter a password to enter the call households, again by pressing the open button households Implement change password function, the password stored in the 24c02 can guarantee non-volatile password. Eight LED lights represent 8 households, which opened the door keys are shared, but also with forgotten password recovery button, analog restore factory settings, Display part LCD1602. Program is divided into three modes, namely, waiting for a password to modify call households 3 modes, which is the main input wait state, so call households entering the password change mode if Their long time operation can be switched to the standby input mode.)
