画面与程序卡在第一帧，有时运行几秒后卡住

Chinese 中文

程序是新建文件自带的，点击左下角开始后画面出现第一帧（有时甚至不会出现）就停止，有时运行几秒后停止，程序运行结果也随之停止。我再次点击左下角希望结束程序却显示忙碌中。我使用的是h7p lu s

Hi, can you update your firmware to the latest? Do Tools→Install Latest Development Firmware. Also, please use the latest version of OpenMV IDE v4.8.7.

Thank you for your reply, but it’s still not working. The current situation is that when I click the bottom left corner, the device disconnects.

Can you post a video showing what is happening? The H7 plus is extremely solid. This type of failure likely has some weird cause.

sorry, i’m a new user,i can’t post video

i will show you my code

sensor.set_framesize(sensor.QQVGA)  # Set frame size to QVGA (320x240)
sensor.skip_frames(time=2000)  # Wait for settings take effect.ssekuaig
clock = time.clock()  # Create a clock object to track the FPS.

I’m not sure if you can use Chinese names for functions and variables reliably. can you post the code with everything using ascii only? I will have an easier time debugging.

I’m borrowing the original poster’s thread to raise some of my questions. I also encountered lag issues. The lag occurs after I extract the facial feature points during face recognition. The whole screen freezes, and then the program stops running. I thought it was a firmware issue, but after updating the firmware, new problems appeared. …

Hi, we are resolving some issues with the newest protocol. Please use the latest stable firmware until we have these resolved.
