stm32f103vet6实现printf重载(printf function about stm32f103vet6)

波形发生器，无线接收，机械手，马达速度控制，计时器等例程，初学者的好帮手(Waveform generator, wireless receiver, robot, motor speed control, timer routines, good helper for beginners)

说明：  在SMT32F7平台上的基于FreeRtos系统的Lwip1.4的移植(Transplantation of Lwip1.4 Based on FreeRtos System on SMT 32F7 Platform)

基于stm32的485编程范例，RS-485采用平衡发送和差分接收，因此具有抑制共模干扰的能力。(Based on the 485 programming paradigm of stm32, RS-485 uses balanced transmission and differential reception, so it has the ability to suppress common mode interference.)

说明：  MCP5634平台下的串口收发，底层寄存器配置、中断设置等(Serial port receiving and sending on mcp5634 platform)

基于stm32的飞行器代码，用遥控器可以实现对飞行器控制飞行，可以通过GPS进行定位.(Stm32 code based aircraft, with a remote control can be achieved on aircraft flight control, can be located by GPS.)

这是一个用keil-51编写的C51程序，里面含有温度控制的PID核心算法，这为温度的精密控制提供了保证，同时有液晶12864的驱动，而且有PCB电路图，供大家学习和参考。(This is a written with keil-51 C51 program, which contains the core PID temperature control algorithm, which is the precise temperature control can be ensured, while an LCD 12864 driver, but also PCB circuit, for your study and reference.)

此程序可实现长度为8位，周期为255的m序列，此序列可当做伪随机信号发生器，模拟信道噪声。(This procedure can achieve the length of 8 bits, the m sequence of 255 cycles, the sequence can be used as a pseudorandom signal generator, analog channel noise.)

采用8位MCU的燃气点火器的源程序，采用汇编程序编写(8-bit MCU gas ignition source, using assembler programming)

T2 定时器应用简例，利用T2定时器控制小车的调速与测速功能的新定时办法(T2 timer application simple example, the use of the T2 timer to control the car' s speed and the speed function of the new timed approach)
