I understand it's a random issue, but I can't begin to debug and fix it unless I can see it happen. Unless you can provide a small example that shows this issue (even if it happens randomly) I can't do anything about it.

I can't reproduce this issue, this is what I tested: import sys import os import math import json current_work_directory = os.getcwd() def uprint(*text): with open(current_work_directory + "Soccer/log/output.txt", 'a+') as f: print(*text, file = f) print(*text ) for i in range(0, 10): uprint("test")...

I'll test it, but you need to add a "/" I think getcwd returns the basename without a trailing slash (which also means the replace(\, /) is not needed).

What is current_work_directory ?

If it's a global variable it should be declared with global, I need to see the full code and how this is called.

That 400KBs some of it is also used for the framebuffer, you should try to lower the resolution or make the model smaller. We'll fix the docs to explain this better.

Hi,

poll/select is not implemented for the WINC1500, you can use sockets in non-blocking mode instead, see:

viewtopic.php?f=6&t=1269&p=7832&hilit=poll#p7839

Please attach the pics to your email.

Sure, please send us an email [email protected]

Can't run models from SD they have to be loaded in RAM, and yes you can use STM32Cube.AI but you have to build the firmware from source, see the docs here:

https://github.com/openmv/openmv/blob/m ... /README.md

Use an SD card and you have to use a smaller model, not all the memory is available for loading networks.

If you use the same pins and use ov2640 (or any other sensor that we have a driver for) then it should work with the default firmware.

Please post the script.

Hi, I've seen a few attempts on the forums to play WAV files, but no recording, and yes we have two I2C interfaces on the pin header.

Yes, I think it was this dataset: http://portal.uc3m.es/portal/page/portal/dpto_ing_sistemas_automatica/investigacion/IntelligentSystemsLab/research/InfraredDataset https://e-archivo.uc3m.es/handle/10016/17370 Note, you need to downsample the 14 bit images to 8 bit before training and testing, and u...

If you think there's a bug please report it on github, also if you want to add your script to the examples please send a pull request. I have made a few observations conscerning the residual standby current - in principle it should be possible for this to be about 60uA, with the chips used, but it i...

Do you connect it to an external 5V output ? The camera doesn't have a 5V output, also if the sensor's I/O is 5V it won't work.

see the low power examples in the menu.

Never mind, I already fixed it, you should be able to load jpg images in the next release. So this should work:

Hi,

Thanks, as I say I only need to be able to load the compressed image again, not actually decompress it. So even a way of loading a file onto the frame buffer would suffice.

I see, that's a lot easier to implement. Okay please open an issue on github and I'll get right on it.

The IDE is open-source, it doesn't mean it's free. You can still use it without a license key, if don't mind the windows that show up, buying a key however supports the project.

It's already on the todo list, it's just a lot of work to get JPEG decoding working, but I'll see what I can do.

Nope, the RTSP server example didn't help. Running it in station mode works, VLC can connect to it. Running it in AP mode, I get the error: VLC could not connect to "0.0.0.0:554". Your input can't be opened: VLC is unable to open the MRL 'rtsp://0.0.0.0:554/'. Check the log for details. mjpeg_strea...

Fixed.

Hi, it's seems to be a bug when using an open network (no security). I'll look into it, in the meantime if you switch to WEP it works: import time, network, usocket SSID ='OPENMV_AP' # Network SSID KEY ='1234567890' # Network key (must be 10 chars) # Init wlan module in AP mode. wlan = network.WINC(...

Try https://docs.openmv.io/library/omv.imag ... age.binary

There shouldn't be any problems, the power supply will use the input VIN.

After research, I found that drawing before computing messes with the source image. Well noted, this gave me a way better accurate reading! Now what is the correlation between the min temperature and the min threshold and the max temperature to the max threshold? The min and max temperatures are sc...

One comment on your code, you should move the drawing after get_statistics.

This does not work well on a virtual machine because the IDE resets the camera to run the bootloader, at which point it gets disconnected from the VM.. I think with virtual box there was a way to assign the device to the VM, you should try that if it's possible.

The source code is all on github: https://github.com/openmv/openmv you can learn by looking at how things are done.

Hi, try the latest 3.6.7

Yes, you can download any older release from here:

https://github.com/openmv/openmv/releases

BTW we fixed the issue and there should be an udpate.

I already fixed it, we just need to test this and then I'll make another patch release today.

DNS is not able to resolve the host.

Not much processing happens, the text get copied to a buffer if USB is connected, so you can leave the print statements. If you want check if USB is connected try:

Wait, what do you mean? We support TCP and we sockets are just data over TCP.

The MicroPython module/code that does that depends on lwip, that's why it's not enabled.

Hi, there's no builtin support for websockets because it requires LWIP which we can't use with WINC.

No, it needs to be added to builtin modules in mpconfigport.h.

We have an RPC library that lets you connect to and control the cam, have a look here: https://github.com/openmv/openmv/blob/m ... /README.md

Why do you have to post this 3 times in all topics ?

Your code is fine and you have the latest fw.. Try removing the sensor and attaching it again with the screws so it's making full contact.. Please note you should Not remove/attach the sensor with the cam plugged in, otherwise it could short something.

The firmware file should be on SD card, please undo the changes to the path read the comments in the script.

Hello,

You can sponsor us now on github:

If main.py is not found the code waits for input from the user/IDE. If the FS is created on flash it creates the default main.py (blinking LED). The main.py is not created if SD is used. That's the default code if you want to change something you have to rebuild from source.

These are the possible values for the WINC1500. Note these constants are not exported to Python code so you have to use numeric values if you really have to use them: // Socket option. // Used with the @ref setsockopt function #define SOL_SOCKET 1 // SSL Socket option level. // Used with the @ref se...

Please report a bug on guithub and I'll fix it.

For example, the docs are crystal clear that nothing above 32GB The docs are wrong/outdated, higher capacity SD cards have been supported for years. but the response is...fuzzy I use Samsung EVO/U3 32GB and 64GB and they both work fine. My reply can't be more specific. EDIT: I see you want me to te...

I appreciate you theorizing as the problem, but are you saying I have discovered this issue a year after the H7's release and there is next to no discussion about it on the boards? I can't be the first person to run up against this. How do you deal with this exact same issue on your own H7s, of whi...

Do you know that class 10 cards work or do you recommend a different class perhaps? What class 32GB cards do you have at your disposal for testing?

Class 10 is not the fastest, UHS/U3 is the fastest. I use Samsung EVO/U3 32GB and 64GB and they both work fine. Try formatting the card with exFAT.
