用51单片机模拟dds产生正弦波，方波，三角波，幅度频率可控。(Dds generated using 51 MCU simulation sine, square, triangle wave, amplitude frequency control.)

用于单片机C语言开发,是你使用单片机进行研究的好帮手(for C language development, the use of SCM is that you study a good helper)

本例程是基于1602液晶显示实时时钟，使用DS1302，使用51系列单片机，通过本例程可以熟悉1602和1302的操作，适合单片机课程设计或者毕业设计的一项功能，程序编译通过可直接移植使用(This routine is based on the 1602 LCD real-time clock, use the DS1302, use 51 series, through this routine may be familiar with the operation of 1602 and 1302, for SCM curriculum design or a functional design Graduation, a program compiled through direct transplantation use)

说明：  四轴的简单原理图，包括Wifi模块，电源模块，通信模块等(simplified scheme layout of a four-wing drone)

西南交通大学图形学实验的第二个，响应键盘的系统键和非系统键(Second, the system in response to keyboard keys and key non-system experiments Southwest Jiaotong University Graphics)

C语言程序，ieee标准格式转浮点型数字(c language, ieee to float)

能够实现通过红外遥控器控制电机的正反，停止转动。(Can be achieved through an infrared remote control motor forward and reverse, stop turning.)

stm32f103zet6 KEIL MDK 包括功能 3.5寸TFT彩屏 fsmc接口通讯； 电阻触摸 xpt2046 采用SPI通讯 AD数据采集 DMA传输 2000点，以及平滑滤波；DA输出； (Stm32f103zet6 including 3.5-inch TFT color screen fsmc interface communication Resistive touch xpt2046 using SPI communication AD data acquisition DMA transfer 2000 points, and smoothing filter DA output )

说明：  通过单片机AT89C2051采用DS1820上的温度,并通过串口发出(The temperature on DS1820 is adopted by AT89C2051 single chip computer and sent out through serial port.)

这是C8051F040单片机开发的一个串口通信程序，通过串口调试测试程序正确，可以直接拿来用，对使用C8051F040单片机开发者具有一定的参考价值。(This is a C8051F040 microcontroller serial communication program developed by serial debug test procedure correctly, you can directly make use of them, on the C8051F040 microcontroller developers to use a certain reference value.)
