• 免费好用的星瞳AI云服务上线!简单标注,云端训练,支持OpenMV H7和OpenMV H7 Plus。可以替代edge impulse。 https://forum.singtown.com/topic/9519
  • 我们只解决官方正版的OpenMV的问题(STM32),其他的分支有很多兼容问题,我们无法解决。
  • 如果有产品硬件故障问题,比如无法开机,论坛很难解决。可以直接找售后维修
  • 发帖子之前,请确认看过所有的视频教程,https://singtown.com/learn/ 和所有的上手教程http://book.openmv.cc/
  • 每一个新的提问,单独发一个新帖子
  • 帖子需要目的,你要做什么?
  • 如果涉及代码,需要报错提示全部代码文本,请注意不要贴代码图片
  • 必看:玩转星瞳论坛了解一下图片上传,代码格式等问题。
  • 代码也不报错,连接openmv运行就会自动终止运行,串行终端提示这个是怎么回事啊?

    • 这个代码是哪里有问题吗?怎么运行不了也拍不了照片,传不了值?自动就停止运行了?跟arduino连接也没反应

    • 刚刚又改了一下代码,发现不报错了,但是串行终端没有输出数据,这个代码是哪里出问题了呀?



    • 错误太多,实在没法改。
