说明USB设备无法识别。解决方法，到网络上下载对应的驱动程序，下载后安装上即可识别。
如果您的电路板未出现在可用端口中,则可能意味着您缺少软件驱动程序,或者您的 USB 线是充电专用线。请确保您使用的USB 线是支持数据传输的线缆,仔细检查产品文档以确定是否需要驱动程序,然后尝试使用计算机上的其他 USB 端口。 像往常处理技术问题时,有时只需重新启动 Arduino 软件或整个计算机,然后重试即可。 这里也...
but the USB to serial TTL converter I ordered from Ebay still hadn’t arrived. So I got all these cool bluetooth 4.0 and Wi-Fi modules I couldn’t use, or so I thought at first. In this tutorial I’ll show you how to use an Arduino as a bridge between...
另一件重要的事情是,Arduino 和 BW21-CBV-Kit 的 GND 引脚应相互连接。 接下来将在串行监视器中观察 BW21-CBV-Kit 接收到的数据。(注:如果不知道 BW21-CBV-Kit 开发板连接到哪个端口,请先在 Windows 的 "设备管理器 "中查找。BW21-CBV-Kit 被连接为 "mbed 串行端口"。例如,找到 mbed Serial Port (C...
Re: Arduino showing "unknown Device" Post by adafruit_support_bill » Wed May 30, 2012 10:00 am The UNOs have an Atmega 8U2 (or 16U2 on later models) processor for the USB/Serial function. These processors have their own ICSP programming connectors, and some have been able to resu...
The Arduino serial library will be useful throughout these tutorials as it provides an easy way to display the result of your Arduino’s activities on your computer screen. In this Arduino Serial example, we will write text to the Arduino serial port, which will send it over the USB cable...
Serial communications provide an easy and flexible way for your Arduino board to interact with your computer and other devices. This chapter explains how to send and receive information using this capability. Chapter 1 described how to connect the Arduino USB serial port to your computer to upload...
The USB Host shield has a separate chip (usually Max3421E), which provides USB Host support. Once you have this shield, your Arduino board can act as USB Host and you can connect other USB devices like keyboard, mouse or even an Android phone and communicate with the device from Arduino...
