ISA 10M网卡电路设计,对电路开发很有帮助(ISA card circuit design, circuit development helpful)

用STM32模拟IIC主机，读取24c0x的内容。(Using STM32 simulation IIC host, read the contents of the 24 c0x.)

SSD1306的OLED上显示字符、汉字、画点、画线、画圆的驱动函数，以及一个基于MSP430单片机的各个功能的测试文件。 整个文件采用模块化的划分方式，程序清晰容易阅读，适用于对OLED不熟悉的初学者直接移植使用，非常方便。(SSD1306 OLED display characters, Chinese characters, painting, line drawing, Circle Drive function, and one each function based on MSP430 single chip microcomputer test file. The entire file by dividing the modular, procedures clear and easy to read, suitable for beginners unfamiliar with OLED transplanted directly use, very convenient.)

基于STM32单片机，通过W5500以太网芯片下载APP的IAP程序，实测正常使用。(Based on the STM32 microcontroller, download the APP IAP program through the W5500 Ethernet chip, and measure the normal usage.)

该防盗系统使用热释电红外传感器作为人体探测模块，并将防盗系统设计为两个用户可选择的模式：在家模式和离家模式，当处于在家模式时，如果传感器检测到有人进入监控范围，则自动响起门铃提醒用户有访客，就不会发生误把访客当作盗贼的报警事件了；当处于离家模式时，如果传感器检测到有人进入检测范围，则开启声光报警模块进行报警。同时，该系统为密码控制系统，用户通过输入正确密码才可改变模式和解除警报，这也增强了该系统使用的可靠性。(The anti-theft system using pyroelectric infrared sensor as the detection module, and alarm system design for the two user selectable mode: home mode and home mode, when in the home mode, if the sensor detects a person into the monitoring range, will automatically alert the user to a visitor rang the doorbell, will not happen take the visitor as an alarm event of thieves; when in the home mode, if the sensor detects a person into the detection range, open alarm alarm module. At the same time, the system is a password control system that allows users to change their mode and lift their alarms by typing in the correct password, which increases the reliability of the system.)

STM32L151的例程，包括ADC,DAC,DMA,PWM,EXTI等等，很全(STM32L151 routines, including ADC, DAC, DMA, PWM, EXTI, and so forth, very full)

基于51开发平台，采用指纹十本模块，实现指纹识别，存储，对比等程序。代码注释详尽，采用外部EEPROM存储。(51 based on the development platform, using the ten fingerprint module, fingerprint identification, storage, comparison program. The code detailed notes, using external EEPROM storage.)

STM32 RTX实验 内存管理,移植和学习RTX操作系统非常有用(STM32 RTX)

仿真电话键盘拨号的电路图 C 以及HEX文件 是我的单片机考试作业(this is my master piece)

关于驱动led灯的驱动程序，希望大家共同进步，也希望快点让我通过。(About driving the led driver, I hope you make progress together, also hope to hurry up and let me pass.)
