In this project, we will build a remote-controlled Arduino Air-Boat that can be controlled wirelessly using the 433 MHz RF… Be a part of our ever growing community. Semicon Media is a unique ...
Add a description, image, and links to the ch340-usb-driver topic page so that developers can more easily learn about it.
A Line Follower Robot (LFR) is one of the most popular Arduino robotics projects that teaches core concepts of automation and sensor integration. This step-by-step guide will show you how to build a ...
如图15所示,将ESP8266模块与单片机连接好后,要用串口调试助手调试它。使用TTL转USB模块(CH340)连接电脑和模块,用电脑给它烧录AT固件后,调试完后,才可以使用。它的程序流程为:首先初始化模块的引脚,然后开始搜索附近的热点,连接上热点后,就可以上传 ...
本文是基于STM32G431的LL库做的,针对裸机的串口接收和发送库。其中UART接收采用DMA+idle中断+多级缓冲模式。
写本文之前,先写点相关的扩展内容。 STM32属于ARM中Cortex-M系列处理器,比如:STM32F1数据Cortex-M3,STM32F7数据Cortex-M7。 可以参看我之前分享文章:从Cortex-M到Cortex-A认识ARM处理器,了解一下关于ARM处理器的种类。 本文主要结合Cortex-M3下面STM32F1系列处理器为例来 ...
