基于stm32的PID温度控制，采用18B20反馈，恒温40度。用于医疗自动分析。稳定温度在正负0.5度内(Stm32 based PID temperature control, the use of 18B20 feedback, constant temperature of 40 degrees. Automatic analysis for medical treatment. Stable temperature within plus or minus 0.5 degrees)

RA8875 官方Touch驱动源码 已经参照(The official RA8875 Touch driver source code, have reference )

红绿灯控制程序，基于stc51系列单片机(Traffic light control program, based stc51 series microcontroller)

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.)
