51单片机串口·通信检测151单片机连接bmp085气压传感器，测得大气压(51 single chip microcomputer serial communication and communication detection 1)

51单片机新型按键扫描，不用10ms延时消抖，实时性大大提高。每个按键有长按短按功能，采用结构体对象化编程，增加按键极度方便。(The new key scan does not use 10ms delay to eliminate jitter, and the real-time performance is greatly improved. Each button has a long press, a short press function, the use of structured object programming, increasing the key, extremely convenient.)

在stm32单片机上，用IO口的上升沿和下降沿中断设计的I2C从机代码。测试通过。所有过程用状态机来控制，没有cpu空延时。 核心代码和单片机相关代码分开，方便移植。 主要用在项目验证和学习交流！(On stm32 microcontroller, with rising and falling IO port interrupt design of I2C slave code. The test. All the process is controlled by a state machine, no cpu empty delay. Microcontroller core code and related code separate, easy to transplant. Mainly used in the project validation and exchange of learning!)
