USB CDC settings for STM32F407 - DESCOVERY with examples

HDG12864F-3的液晶驱动，有Protues硬件仿真图，方便初学者参考(HDG12864F-3 LCD driver, a Protues hardware simulation map, easy reference for beginners)

功能非常强大的计算器，单片机飞思卡尔LCD屏幕显示，可以完成加减乘除还有括号运算(Very powerful calculator microcontroller Freescale LCD screen display, the completion of the addition, subtraction there brackets operator)

个人收集的各种串口电路图,程序,讲解比较详细,对初学者应该帮助比较大(Personal collection of various serial circuit, procedures, explained in more detail, for beginners should help more)

说明：  stm32f103vet6实现printf重载(printf function about stm32f103vet6)

本人做的四旋翼飞行器源码，这个是纯遥控版，可以实现稳定飞行，内含mpu6050,5883l，等传感器驱动，以及四元数姿态解算，和PID，以及遥控的解锁上锁等(I do four rotorcraft source, this is a pure version of the remote control, you can achieve a stable flight, containing mpu6050,5883l, and other sensor-driven, and quaternion attitude solution, and PID, and a remote unlock locked, etc.)

I2C总线协议应用,利用单片机中断实现可以记忆的时钟,程序自己已经调试过，绝对能用(I2C bus protocol applications, the use of the microcontroller interrupt memory clock, program debugging, and absolutely can)

说明：  DS2781测试程序，网上下载的，有一定参考价值(DS2781 test procedure)

基于ST7920A控制器的128*64液晶驱动程序，包括汉字，字符，字符串，以及图形显示。可显示任意长的中文及字符串。(ST7920A controller based on the 128* 64 LCD driver, including Chinese characters, characters string, and graphics. Show arbitrarily long string and Chinese.)

说明：  STM32F103控制继电器输出，可扩展应用至其他程序(STM32F103 Control Relay Output)
