    • 运行程序时报错咋处理

      从SD卡里导入文件进行特征点检测，提示运行内存不足，除了降低图片分辨率外，还有其他技巧可以解决这个问题吗？

    • 找不到DfuseDemo.exe在哪里下载

      下载IDE的时候，只有IDE.exe，并没有OpenMV IDE的一个大文件夹，因此无法如教程里那样找到烧录软件和最新固件，请给一个下载链接。0_1589425519596_777.PNG 0_1589425534504_888.PNG

    • 接上一个摄像头失效的问题

      为什么open mv连着电脑时，如果电脑没电关机了，充电后再次连接open mv 时就连接不了了？是电脑关机时有电信号传给摄像头，然后把它烧坏了吗？我测摄像头stm32的电压时，依旧还有3.3V。

    • Openmv Cam用着用着突然就坏了

      连着openmv cam的时候，电脑没电关机了，我记得是点了重置之后电脑才关机的，但是没拔数据线。然后电脑充电后再次连接Cam的时候，就识别不了openmv cam了。我按照你在论坛里发的那个检查驱动、检查数据线、升级固件、dfu啥的操作了，感觉试了没用，而且重点是，由于由于无法识别openmv cam，感觉它的重修编码并没有被执行进去，连接跳线也感觉并没有进行编码，只是摄像头发热的厉害。
      还有什么方法吗？如果寄回维修，咋收费？去年九月份买的。0_1589380932462_IMG20200513200804.jpg
