F5 refresh programing tool

测脉宽，基于STC15W单片机的测试要在1.3管脚加一个脉冲然后通过OLED 屏幕显示(Pulse width measurement)

MPU6050＋舵机，可实现平台的稳定。适用于STM32RCT6(MPU6050 + rudder can realize the stability of the platform. Applicable to STM32RCT6)

STC单片机的EEPROM的驱动程序，包括读写eeprom的程序(AVR and C language entry, including the introduction of AVR microcontroller and the c language entry and application.)

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.)

基于MSP430F149单片机设计一个8路模拟信号，8路开关信号的数据采集系统。用数码管显示采集通道和结果，循环显示各通道数据(MSP430F149 MCU-based design of a 8-way analog signals, eight-way switch signal data acquisition system. Acquisition channels with digital display and results, cycle through each channel data)

说明：  NEC协议的红外遥控器解码程序，程序占用资源少，在51等单片机上验证OK。(ir decode for NEC protocal.)

汽车信号灯控制系统的设计 汽车上的信号灯有:转向灯(左前灯、右前灯、左后灯、右后灯，仪表盘上的二 个指 示灯 )及夜间示 宽灯等 。 当汽车转 弯 、刺 车 停 靠时 ，转 向灯 发出不同 的信号 ；夜问 ．则 点 亮示宽 灯。汽 车转弯或停 靠时 ，相应的 信号灯要 发出 闪烁 的灯光 信号 ， 目前 国内广泛 缱 用 电热 式闪光 器产生 闪光信 号 。(Auto Light Control System lights on the car include: turn signal (front left light, right front lamp, left rear lamp, right rear lights, two lights on the instrument panel) and night lights, wide display. When the car turn, stop puncture car, the turn signal send mixed signals nighttime. The width light is lit. Car turns or stops, the corresponding signal to a flashing light signal, the current domestic-type electric flash wide loving generated by the flash signal.)

基于NRF2401与单片机的的通信-NRF2401与8051单片机配合完成数据的收发并附带电路图（protues格式）以及电子报告（doc格式）(Microcontroller Based NRF2401 and communication-NRF2401 and 8051 with the completion of the data transceiver and comes with schematics (protues format) and electronic report (doc format))

基于STM32的Lora无线通信sx1278的测试代码(Test code for Lora wireless communication sx1278 based on STM32)
