Troubles grabbing settings file

[schelcc]

I have the newest available image for frcvision

When I attempt to upload your code I get the following error:

Traceback (most recent call last):

  File "./uploaded.py", line 684, in <module>

    if not readConfig():

  File "./uploaded.py", line 631, in readConfig

    j = json.load(f)

  File "/usr/lib/python3.5/json/__init__.py", line 265, in load

    return loads(fp.read(),

  File "/usr/lib/python3.5/encodings/ascii.py", line 26, in decode

    return codecs.ascii_decode(input, self.errors)[0]

UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in position 174: ordinal not in range(128)

Waiting 5 seconds...

I attempted to comment that section out, to no avail.

This error occurs anytime I try to execute anything via the web dashboard. The pi was re-imaged today, so I doubt it's that.

Can you grab the /boot/frc.json file from the Pi and upload it as an attachment here? That file is a text file and shouldn't have any binary data in it.

Github won't let me upload a .json, so here is it pasted:

{
    "cameras": [
        {
            "name": "",
            "path": "/dev/v4l/by-id/usb-Microsoft_Microsoft®_LifeCam_HD-3000-video-index0",
            "pixel format": null,
            "stream": {
                "properties": []
            }
        }
    ],
    "ntmode": "client",
    "team": 3656
}

I just updated this with the proper boot/frc.json, I think the problem is the '®' but thats part of the url, and removing that makes the path useless.

[schelcc]

That is the root of the problem. My issue now is that I can't get the camera without that address.

[PeterJohnson]

Agreed there's a bug here but the workaround is straightforward. You can get the camera without that address. If you only have one camera, it will always be /dev/video0. The path you've set up is only necessary to disambiguate cameras when you have more than one.

Actually there's an easy fix that should let you keep doing what you're doing. See https://stackoverflow.com/questions/35051867/json-load-function-give-strange-unicodedecodeerror-ascii-codec-cant-decod Add a 3rd parameter to the open() line on line 94 or so, encoding='utf-8'. I'll PR a fix.

That fixed it and it works perfectly now, I'm going to close it.
