  • 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。
  • 代码出什么问题了吗?为什么在ide里运行是就卡住了呢?但是没有报错



    • # This example shows off single color RGB565 tracking using the OpenMV Cam.

    • 没有卡住,因为你的死循环里又套了一个死循环,你看不到现象而已。



    • @kidswong999 如何破解呢?您应该可以看出来我想做一个识别颜色后输出模拟信号的程序
