根据gps坐标计算距离

圆形按钮，还是界面上的小零件，需要的朋友可以拿去参考参考(Radio button, or the interface on the small parts needed can be taken to refer to refer to a friend)

说明：  VISUAL C++与MATLAB 混合编程及接口调用，麻烦给我早点开通，(VISUAL C and Matlab interface and called for the trouble I opened earlier, thank you)

DHT11的驱动程序代码，可以用于89C51等单片机对DHT11温湿度处理器的驱动(Mover for DHT11)

主控芯片为STM32F103VET6，通过DMA + SPI的方式驱动WS2812B型全彩RGB5050 LED，共16颗LED，程序已在开发板上成功验证。(The main control chip is STM32F103VET6, and it drives WS2812B type full color RGB5050 LED through DMA + SPI, a total of 16 LED, and the program has been successfully verified on the development board.)

说明：  驱动，一份adv7842的驱动，可以借鉴使用(driver,adv7842 driver,luoji)
