c8051f320 usb 接口驱动程序 和上位机机通信软件及API函数。(C8051f320 usb driver and superior communication software and blast API.)

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

基于51单片机设计的万年历，采用LCD1602实现时间的显示（年月日时分秒）时间以及闹钟的设置(Based on the calendar designed by 51 single chip computer, LCD1602 is used to realize the display of time (year, month, day, hour, second) and the setting of alarm clock.)

说明：  基于STM32 hal库的CAN驱动，仅有驱动部分，收发均测试通过。(The CAN driver based on STM32 Hal library only has the driver part, and both transceivers and receivers have passed the test.)

说明：  两脉冲频率平均值计算 两脉冲频率平均值计算 两脉冲频率平均值计算(Two pulse frequency average of the two pulse frequency average of two average pulse frequency)

很好的单片机学习资料，c语言开发，值得去参考学习(it is nice to have it to learn mcu)

松翰单片机编译工具。松翰单片机编译工具，里面有一些用法。可以仿真2711，2708，2501等。(Loose hands MCU compilation tools. Loose hands MCU compilation tool, there are some usage. Can the simulation, 2711270, 8250 1, etc)

HT1621是128点内存映象和多功能的LCD驱动器HT1621的软件配置特性使它适 用于多种LCD应用场合包括LCD模块和显示子系统用于连接主控制器和HT1621的管 脚只有4或5条HT1621还有一个节电命令用于降低系统功耗(HT1621 is 128 memory mapping and multi-function LCD drive HT1621 software configuration properties make it suitable Used for a variety of applications including LCD LCD module and display subsystem is used to connect the main controller and HT1621 tube Only 4 or 5 foot HT1621 there is a power saving command is used to reduce the power consumption of the system)

运用单片机实现烟雾、煤气报警和短路自检，主要用到ADC0809，AT89S51等。本项目最终做成实物，并能良好实现功能。有protel原理图，PCB布线图，完整的论文中有详细程序介绍。(Application of single chip microcomputer gas alarm and smoke, short circuit self-checking, mainly used in ADC0809, AT89S51 etc..This project eventually made real, and can well realize the function.Protel PCB schematic diagram, wiring diagram, the complete paper.)
