Frequency-Meter

基于卡尔曼滤波的MPU6050例程，效果很好。(Based on the Calman filter MPU6050 routine, the effect is very good.)

12864液晶显示驱动，即Proteus中HDG12864f-3的驱动程序(12864LCD driver, the Proteus in HDG12864f-3driver )

基于stm32数字示波器 嵌入ucos操作系统 以及GUI显示界面(Based stm32 digital oscilloscope ucos embedded operating system and GUI display interface)

MSP430F147 FLASH功能例程

js to use serial and configuration for quadcopter

说明：  使用msp430f5529产生pwm波的基本例程(Using msp430f5529 to generate PWM wave basic routine)

这个是官网没有提供的RTC实验代码，时间通过串口输出。可以方便你快速使用MSP430F5529的实时时钟。(This is the official website did not provide the RTC experimental code, the time via the serial output. Allowing you to quickly use the real-time clock of MSP430F5529.)

51单片机与NFR24L01连接原理图，基于完整的ASM程序代码。双方都要采用项目的电路。(51 and NFR24L01 connection diagram, based on the complete ASM code. The two sides should adopt circuit project.)

利用c51单片机实现计算器的功能 例如：普通的加减乘除，还有2进制等功能(C51 MCU using calculator functions such as: ordinary addition and subtraction, multiplication and division, there are two binary functions)

1000以内所有的完数，比较简单，用于学习和交流(1000 all finished within few, relatively simple, for learning and communication)
