应该是烧录软件不能读熔丝位或者写入,提示连线错误 Pin27_UCAP断路(拆掉C8电容):插上USB口,电脑端口显示unknown device。烧录软件可正常读取熔丝位 Pin28_UGND断路:没测。 Pin29_D-断路(断开D-线):插上USB口,电脑端口显示unknown device。未烧录引导程序时在设备管理器的其他里显示16u2,烧录后则在设备管理器的...
如果您展开节点,您会看到项目引用了一个android.jar,它包含您选择的 Android 版本的系统类文件;一个usb.jar,它包含您与 ADK 设备进行 USB 通信所需的 USB 特定类;以及一个maps.jar,它用于 Google Maps 集成。 下一个文件夹叫做assets,它通常包含你必须自己管理的额外资源。您必须通过它们在应用中的相对路径来引...
给arduino通电,然后短路arduino最靠近usb连接口的两个针脚几秒钟。 打开设备管理器,会出现Other device> unknown device。 右键>Update Driver Software, Browse my computer for driver software Let me pick a list... Next Have disk Browse... 选择unojoy中的drivers/Arduino Uno.inf OK Next Install 步骤4 ...
Look under Ports (COM & LPT). You should find an open port named "Seeeduino v4.2". If there is no COM & LPT section, look under "Other Devices" for "Unknown Device". Right click on the "Seeeduino v4.2" port and choose the "Update Driver Software" option. Next, choose the "Browse...
### 1. 上传失败-**现象**:提示`avrdude: ser_open(): can't open device "COMx"`-**解决方案**:-检查端口是否被其他程序占用-重新拔插 USB 线-重启 Arduino IDE ### 2. 驱动未正确安装-**现象**:设备管理器显示 "Unknown Device"-**解决方案**:-下载 [Zadig 工具](https://zadig.akeo.ie/...

Find Unknown Device and then right click and select Update Driver Software . Choose "Browse my com uter for driver software" to search for drivers manually. Click "Browse" and find the director location of the Arduino IDE where the installation files are located . Inside this director will be...
One potential way to improve upon this is to add a variable to the Encoder library, tracking themicros()timestamp of the most recent position update. I can then query that timestamp from my code later, instead of callingmicros()myself which pads an unknown delay. I found the encoder libr...
Check to see if your Arduino shows up under Windows Device Manager. Search Device Manager on your computer and run the executable. Expand the USB section and see if your Arduino is listed. If it is not, you may need to install the drivers for your Arduino. See the External Link: Install...
