TinyDuino / How to attach external power switch?

« Last post by lcpalm on April 14, 2021, 12:50:58 PM »

Hello,

I have a TinyZero project and would like to attach an external power switch (have wires running to a power switch attached on the enclosure of my project).  I bought a little switch, but am not sure how to wire it up to the TinyZero, or if this is even possible?

Thank you!

Hi Réna,

Thanks for your response! Yes, it was something with the serial communication --- I set it to have a 3s delay during startup, and that seemed to take care of it.

I do have another question now -- I would like to set up my TinyZero with an external power switch (like, run wires about 2-3" away so that I can have a power switch on the bottom of my little device I'm building, instead of moving the switch on the card itself.) I bought a little switch but am not sure how to hook it up, or if this is possible...

Should I submit this as a separate question?

Thank you!
Linda

Hello there,

I'm sorry this post was sitting for so long - I missed it!

When a board works attached to USB and then doesn't work wirelessly, it is normally something program-wise in the setup() loop that involved Serial communication, or some logical error that prevents the program from continuing.

If you are still having the same problem - can you attach your code so I can take a look?

Thanks!

General Discussion / Re: DIY TinyTV Kit "card not found!" error

Hello,

The tutorial with the Arduino program, and the code that ships on the TinyTV kits is the same, so this tutorial shouldn't drastically change functionality if uploaded correctly (by selecting TinyScreen+ and the correct COM# in the Arduino IDE): https://learn.tinycircuits.com/Kits/Tiny-Video-Program/

If you loaded the Tiny Video Player program rather than the TinyTV kit program, you can change this in the settings menu once you solve the "Card not found" error: https://learn.tinycircuits.com/Kits/TinyTV-Tutorial/

It looks like you wrote in an email form as well with the same problem, but I will repeat myself here for anyone else having the same issue:
Often when this error comes up, the MicroSD and Audio TinyShield is not plugged into the TinyScreen+ board fully. Do not press with excessive force, but I recommend taking the sd card out, then taking the TinyShield out, and then trying to re-seat the board into the TinyScreen+ connector with even pressure. Test again before closing the TinyTV enclosure.

Best,
Réna

General Discussion / DIY TinyTV Kit "card not found!" error

« Last post by Megabyrne on March 31, 2021, 11:25:18 AM »

I’m trying to set up the DIY TinyTV kit and after assembling the TV I inserted the microSD card switched it on and got a message on the screen about needing to insert a card.

I had loaded additional .tsv videos onto the card before inserting it so assumed that I needed to install the Tiny Video Player Arduino Program which I did and now I’m seeing the error “Card not found”

I thought it might be an issue with the microSD card that came with the kit but after trying another card (which I copied a few .tsv files onto) I receiving the same error.

Is there away to reset it back to the way it was shipped? So that I can start again and try and figure out if the issue is with the card or if I haven't set up the board properly.

The error could come up for many reasons. You can try to post your reply in an incognito browser, or perhaps there was a symbol or other banned behavior that was included in the discussion post.

I tried to post a reply, with just a summary of the audio visual conversion from that, which is more useful to me than the converter in entirety, but I got:

CleanTalk: *** Forbidden. Message seems to be spam.

Hello,

There is a source python file for the TSV Converter. It is attached. It was not previously posted on GitHub since the Windows and Mac apps are all that most people need, but I will make sure it gets added. All of our software is open-source of course, we just missed getting this posted somewhere. 

You should be able to run the python file (dependent on python 2), but do not use the system theme, and you will need to have a copy of FFmpeg to get it working properly. The TSVConverter is mostly a UI wrapper for FFmpeg.

A .tsv file can be an mp4, gif, or converted image

Hope that helps!

General Discussion / open source TSV converter?

« Last post by squid on March 26, 2021, 11:26:19 PM »

Is there an open source version of the TSV converter I could use on Linux?

Looking at playVideo():
https://github.com/TinyCircuits/TinyCircuits-TinyTV-ASK4002/blob/master/examples/TinyTV/videoPlayer.ino#L186

The video format appears to be raw video frame followed by raw audio. The video is two bytes per pixel, so what, 5 bits each rgb and one ignored, or what? The audio is 2048 bytes of 8 bit per sample raw mono audio?

It also looks like there is an audio-free version of TSV, as in this blog post: https://tinycircuits.com/blogs/learn/120988679-putting-images-on-your-tinyscreen

But I don't see any header checks to determine what kind of TSV file it is. Just be careful, I guess?

TinyDuino / Tinyzero won't run off battery?

« Last post by lcpalm on March 23, 2021, 06:11:44 PM »

Hi, I have a TinyZero circuit built, which runs fine off USB but won't seem to run off battery power.

The battery charges (amber light), but when the USB is removed the system doesn't seem to turn on. It's the 3.7V 150mA Li-Ion battery from TinyCircuits.

The circuit is: TinyZero hooked up to micro SD shield and to protoboard leading to an IR sensor pair, which logs beam-breaks.  It works as expected under USB, incrementing the file name on startup (ie every time it's turned on with the power switch on the TinyZero, or the USB is re-plugged in, it starts a new data log on the SD.) But on removing the USB and trying to run off battery power alone, it doesn't turn on and doesn't write any files.

Not sure how to troubleshoot this.... am new to TinyDuino. Thanks in advance for any help!
