OK3-SG-RC522液晶12864十进制串口显示参考程序卡号余额(OK3- SG- RC522 LCD 12864 decimal serial display reference program card balan)

说明：  定时器的使用，让你了解使用定时器所必须的几个步骤！从而能够使用(the use of timers let you know by the use of timers to be a few steps! In order to use)

基于单片机的霍尔传感器测速源码，带有蜂鸣器报警功能。(Hall speed sensor based on single-chip computer source, with a buzzer alarm function.)

实现数码管0-7的静态显示，采用c语言编写。(play led)

用stm32cubemx生成的usb键盘已经配置好带led反回功能(stm32cubemx usb key led ok ok)

stm32f030单片机源程序，还有ds18b20的可用代码(Stm32f030 monolithic integrated circuit source program, and ds18b20 code available)

斯凯科技zigbee无线定位实验说明书，可依据以上说明书进行协议栈定位实验(Skye zigbee wireless location technology experiment instructions, experiments can be carried out according to the protocol stack positioned above instructions)

说明：  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.)

使用STM32+SIM800C，拨打电话、发送短信、透传和手机蓝牙控制等(Using STM32 + SIM800C, dialing, sending short messages, transmission and Bluetooth control of mobile phones, etc)

说明：  通过不同的手势控制小车运动，实现小车的前进、后退、转弯等功能。(Through different gestures to control the movement of the car, the car can move forward, backward and turn.)
