Hey thanks! Looks good and well thought out, so I pulled it in- I think we might change some of the high level stuff, I think we want just one setting for this feature and will either default to the random startup time or 'resume' time etc, but I'm not sure what the outcome will be yet.

I don't have an answer for exactly how/why, but there must be some minor filesystem error that Windows doesn't like, but isn't enough to cause file read/write errors by Windows or the firmware.  We see it here during development when connecting/disconnecting very frequently but don't hear about it from users very often. We're not able to reproduce it here in a way that allows us to determine/fix whatever the issue might be. Reformatting through Windows or the firmware utility(accessed through the Settings page on tinytv.us) is an option if you happen to be deleting most of the videos anyway.

That's pretty much what the current firmware does, the RP2040(and any reasonable low power microcontroller) only has USB full speed, 12Mbit/s. We have some firmware changes we're testing that result in about 1MByte/s, that seems to be about the max that this hardware/USB stack will do. We really underestimated how many people would want to fully load up the storage!

I thought I responded to your last post, sorry- first of all, thank you very much for all your time testing and the amount of patience with this. Is there any chance you're willing to ship the first one back? I'm extremely surprised you have another one with basically the same issue. I'd like to really figure out the root cause which would be a lot easier if I have it in hand. Let me know if you need our address.

Since you asked, the datasheet is at https://www.mouser.com/datasheet/2/15/EC05E-1370804.pdf , the specific PN is EC05E1220401, but again, I'd like to put the time in here and get you a working product!

Thanks,
Ben

Sorry I missed this as well! I agree with your logic- if the high level debounce doesn't work, I think the next step is debouncing per IO pin connected to the encoder. I definitely intended to provide something rather than ask you to dig in that deep. I attached a quick test implementation of that, if you have any interest, let me know what the behavior is on your hardware- 'debounceTimeMS' can be adjusted.

Otherwise, send us an email at info@tinycircuits.com and we'll follow up on the hardware replacement!

Thanks,
Ben

Hey again- sorry we disappeared for a bit, Jason and I have been (extremely) occupied with Mini production! Took a quick look at your first change on Github- looks like a good start. I'll try to respond to your specific comments on Github in the next few days. Thanks for holding off on the second change, I agree that's easier.

Thanks,
Ben

Thank you for posting those details! Can you let me know what "-pix_fmt yuv420p" fixed for you? Maybe we can integrate it into the app.

Hi- can you let me know what version of MacOS you tested on? We haven't had any recent reports of issues on 12.0.0+, but hopefully we can figure out what is going on.

Thanks,
Ben

It's been a little while but we have some instructions at https://github.com/TinyCircuits/TinyCircuits-TinyTVs-Firmware ready for an initial test- let me know how it goes. We might have some missing steps if you're not already a little familiar with the Arduino IDE.

Thanks,
Ben

Hi, thanks for supporting us! Haven't heard of an issue exactly like this. Just to confirm, this is the DIY kit with TSV format videos on the card? Can you let me know what operating system you're on and how you formatted(what utility or settings etc) the card? Can you check for 'hidden' files? Let me know, curious to figure this one out.

Thanks,
Ben

Great! Although it looks like the Github repo is slightly out of date and it's just not yet published to our normal level yet- usually we'd have a basic guide on how to compile. We're just a bit backed up with managing production right now. The other page is specific to the older DIY Kit, so things are similar but not the same. I'll see what we can do to the Github repo today, otherwise I'll probably just post something simple here to get you started. Then we should be able to look at the encoder issue from your other thread, I'm pretty curious about that.

Ok, haven't heard of anything so significant- first of all, we can replace the hardware if you'd like, just email info@tinycircuits.com at any time. Sounds like you're interested in figuring it out/fixing it though based on your other thread. We should be able to in software, I think we just don't have the code quite right for debouncing the encoders. Debug output is disabled on the production build, but you mentioned the Arduino IDE in another thread- if you open the Serial monitor(or any other way of writing data to the USB CDC serial) you can send JSON style strings like {"SET":"channel=2"} to change the channel. This would take the hardware rotary encoder out of the equation, so it could help us determine if that's where the issue is. Let me know.

Thanks,
Ben

Sorry, I missed this! Based on the 'micro USB' part, if you have a Tiny TV DIY Kit or Video Player Kit with TinyScreen+, we haven't been able to get that working due to how little memory the microcontroller has.

I don't know your application but I assume you have some port for power/charging- Maybe a short micro USB extension or microSD card extension or both could allow you to access the microSD card?

Thanks,
Ben

Hi, thanks for your support of Tiny TV 2! Not sure if this is some firmware bug introduced with the video that was added or maybe the encoder for the channel knob is a tiny bit different from others causing the channel to change one way then the other as you suggest. I think I remember one Kickstarter comment that may have been the same issue where someone mentions having two of the 'same' video after adding a video, or similar, which may be a description of the same issue.

Any chance you have the remote? That would be a way to test changing channels without using the channel knob.

If you're able to upload the video to some file sharing site and PM or email me, I could see if I get the same issue here.

Thanks,
Ben

Hi- we have something that fixes some of these issues at https://files.tinycircuits.com/TinyTVConverterWindows1.0.2.zip , let me know if you are able to test it please!
