说明：  1602的显示程序，很简单的那种，可以当入门之用(1602 1602 1602 1602 1602 1602)

说明：  基于正点原子stm32精英开发板和openmv通讯，含openmv端配置，通过openmv（usart3）输出端连接到开发板（usart1）接收端，再由开发板（usart1）输出端输出到电脑，可以用xcom看到(Based on the communication between STM32 elite development board and openmv, including the configuration of openmv terminal, it is connected to the receiving end of development board (usart1) through the output end of openmv (usart3), and then output to the computer by the output end of usart1, which can be seen by XCOM)

用于空中鼠标的加速度计对整个系统的优化，主要用于优化陀螺仪的性能(Accelerometer for air mouse to optimize the whole system is mainly used to optimize the performance of the gyroscope)

好书共享-《实例解读51单片机完全学习与应用》，全实例教学，难得的好教材。(Book Share- Instance interpretation of the 51 single-chip fully learning and teaching of all examples, a rare good material.)

labview编写的机器人手臂运动源码，可模拟手臂的动作及控制过程(robot arm motion labview write source code, can simulate the arm motion and control process)

全自动 hdi板边程式 可以自动跑hdi板边 genesis2000脚本(Automatic hdi board edge program You can automatically run hdi board edge genesis2000 script)

说明：  此应用笔记收集了用软件实现的主模式SPI程序。提供了8 个不同的SPI 主模式传输例。示例中包含SPI时钟相位和极性两个子例程：一个是用C 语言编写的例程，一个是为了提高速度用汇编语言编写的可被C 语言调用的例程。一个例子是在“C”程序中如何调用汇编同时提供了EEPROM接口例子。SPI是摩托罗拉商标。 此文档中描述的SPI功能使SPI处理的软件 最小化。在系统中使用C8051F30X 器件作为 总线上的SPI 主器件。(This application note collection implemented in software SPI master mode procedures. Provides 8 different SPI master mode transfer cases. Examples include SPI clock phase and polarity of the two sub-routines: one is written in C language routines, one is to increase the speed of assembly language written in C language can be called routine. One example is in the &quot C&quot programs how to call assembly also provides examples of EEPROM Interface. SPI is a Motorola trademark. SPI described in this document processing software capabilities to minimize the SPI. In the system C8051F30X SPI device as the primary device on the bus.)

说明：  基于STM32F103设计的简易示波器，功能有：画时域波形及FFT波形，显示峰值及频率。(Simple oscilloscope based on STM32F103,Functions: draw time domain waveform and FFT waveform, display peak value and frequency.)
