开发环境为RVDS4.0，基于开发板Tiny6410，该程序为裸机控制程序，实现串口打印，实现方式：程序下载后打印串口信息； 显示为：a hello Uart(Development environment for RVDS4.0, based development board Tiny6410, the program for the bare metal control procedures to achieve serial printing, implementation: After the download serial print information shown as: a hello Uart)

STM32CubeMX _pwm示例,可以用于参考,希望对大家有帮助(STM32CubeMX _pwm Examples, which can be used for reference, I hope to help you all.)

c8051f340的电机驱动应用程序，包括底层初始化，端口输出控制，ad采样、pwm控制等源程序(c8051f340 motor drive applications, including low-level initialization, the port output control, ad samples, pwm control source)

单片机上电以后LCD屏上显示欢迎回家， 先验证指纹再验证密码 ，同时验证成功开锁 指纹和密码分别可以验证3次 3次都错蜂鸣器响 ，按下manage键进入管理员模式 可以修改密码 删减指纹，指纹用开关量表示(After the microcontroller is powered on, the LCD screen shows welcome home. First verify the fingerprint and then verify the password. At the same time, verify the successful unlocking fingerprint and password can verify that the buzzer rings three times and three times respectively. Press the management key to enter the administrator mode to modify the password and delete the fingerprint. The fingerprint is expressed by the switch.)

单片机系统中经常使用键，该程序实现了ps/2键盘在的单片机系统中的应用(SCM systems often use keys, the program achieved a ps/2 keyboard in the SCM System)

说明：  基于stm32f103的mqtt完整通信的例子，支持TLS加密通信(An example of mqtt complete communication based on STM32F103 supports TLS encrypted communication)
