• 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。
  • wifi模块,传输图片。希望大佬回复



    • 想实现的功能:先拍一张照片,保存到sd卡里面,然后手机链接wifi模块的热点之后,输入ip地址,可以一直看到那一张照片。希望有技术人员能提供代码参考。



    • 参考传mjpeg视频流的例程

      http://book.openmv.cc/example/14-WiFi-Shield/mjpeg-streamer.html

      去掉while循环,就是仅传一次图片



    • 去掉while,改if吗?



    • 节后上班我回去试一下,header应该也需要改⁄(⁄ ⁄ ⁄ω⁄ ⁄ ⁄)⁄



    • 请问一下,节后是什么时候?我有点赶时间,现在能不能指点一下?



    • @yuan 大佬,我把while改了if,但是连接wifi并不能看到哪一张照片,直接被刷过去了。给你看这个图!![0_1523006546556_F1C58~C~F310RA}WTN9(3N.png



    • 加入了传输图片的程序

              s.settimeout(3)

          except OSError as e:

    • 谢谢大佬,但是刚刚我用其它方法已经搞定了。
