Thumby / Re: Blockly graphics not working

« on: December 04, 2023, 10:37:47 AM »

Could you share a screenshot of your blockly program? I can help you debug it that way.

Figured it out, i didn't put the Draw to display block beforehand. Still, if i see draw to display it should draw to display without anything else no?

The draw block/code is required. Drawing everything out to the screen right away would take more time and impact performance. When you draw anything it is put in a buffer very quickly (compared to sending data to the screen) and then the entire buffer is sent in one transmission to the screen when you use the draw block.

Another issue would be that it only works in a loop? First does, second stays on print to display

The first image starts a while loop once A is pressed and then exits out of it when B is pressed.

The second image will only fill the screen with white while A is held down (not just quickly pressed).

TinyTV & Tiny Video Player / Re: Converting videos

« on: November 30, 2023, 10:30:42 AM »

I know there is the TSVConverter program for converting videos (great tool by the way) but I saw somewhere that the TinyTV also will play MP4 video.

Are only certain formats supported? Such as, what audio and video codecs will it play? While TSVConverter is great for ease of use, I would like to use something like HandBrake to re-encode and resize my video files in bulk.

We did make a new version of firmware for the DIY kit that can play .AVI files with jpeg data (not MP4). You can update your TV here https://tinytv.us/Update/. After updating you can't go back easily as of now. The new firmware allows for both AVI and TSV playback.

It should be possible to use other programs to convert your videos but we made a new program for making .AVIs: https://tinytv.us/TinyTV-Converter-App/

General Discussion / Re: Problems uploading sketch to TinySaber

« on: November 29, 2023, 04:10:38 PM »

I'm trying to upload a sketch onto the tinysaber, but I'm having some problems and I'm not sure what the issue is, so if anyone has any insight that would be much apprciated!

Here's the error message I'm, getting:

"Compilation error: fork/exec /Users/luke/Library/Arduino15/packages/arduino/tools/avr-gcc/4.8.1-arduino5/bin/avr-g++: bad CPU type in executable"

Some more info: I'm using a 2018 macbook pro, running version 2.10 on the arduino IDE. Also, just in case it's worth mentioning, once the tinysaber is plugged in (and tinysaber rev2 becomes the preselected board) , the option in the tools-->programmer menu for "Arduino as ISP" is no longer present as it states it should be in the instructions page.

Any insight /help very much appreciated 

The only thing I think to recommend is to follow the TinySaber tutorial while using the 1.8.19 Arduino IDE. You can find that here https://www.arduino.cc/en/software by scrolling down to Legacy IDE (1.8.X)

Do you still make the Wireling LED sensor that you had on your robot at one time?

Please let me know.

Do you mean the color sensor https://tinycircuits.com/products/color-sensor-wireling or the time of flight sensor https://tinycircuits.com/products/tof-distance-sensor-wireling-vl53l0x ?

I wanted to make something not too complicated (blockly) but also relatively hard and currently missing from the arcade (as far as i'm aware), so i'm trying to make an all-in-one calculator, but basically all blocks from the graphics tab don't work, besides the print to display one. It's kinda hard to graph a quadratic funtion without drawing pixels. I tried with a much simpler program too, to see if it was maybe something else, but no.

TL;DR: Blockly graphics tab not working, not my fault

Could you share a screenshot of your blockly program? I can help you debug it that way.

TinyTV & Tiny Video Player / Re: Copying avi file hangs

« on: November 21, 2023, 01:05:21 PM »

TV2. Mac OS 11.7.10. Converted mp4 to avi. Coping to TV2 storage just hangs. Converted file several times with same result.

Hello, how big is the AVI that you are trying to upload? It might just be taking a long time and not updating the progress bar.

General Discussion / Re: New guy here.... Reading Serial Monitor issue- GPS

« on: November 17, 2023, 01:01:30 PM »

So I am new and having issues with reading the serial data with the GPS tracker. 
Setup: Aurdino IDE 2.2.1
Cannot upload with serial monitor on...  So I upload the GPS code given without it.  It pushes fine
Then open serial monitor and see nothing but question marks and characters...
Baud has been tried at 4800 and 9600 and both fail to work.

Any advice to help?  I am sure it is something stupid.
Note that the Baudrates have always matched line 1 to serial monitor

If you're using the code from this tutorial https://learn.tinycircuits.com/Projects/GPS-Tracker-Data-Logger_Tutorial/ then it looks like lower down the actual processor board baudrate is set to 115200. The GPS and SerialMonitorInterface baudrates are separate.

Could you try setting the baurdrate to 115200 in the Arduino Serial Monitor and see if it works?

 I added a new block with a little documentation of it here: https://thumby.us/Blockly/Making-Sprites/#drawing-animated-sprites

Hopefully that fixes your problem.

I swear I managed to get this animated sprite thing to work once before, but I'm using Blockly to import an existing B&W sprite that is 60x40 pix, with the intent that it be loaded as 2 frames (30x40 pix). It is acting all kinds of crazy when displayed, splitting the image vertically also and repeating chucks within the "frame". It's hard to tell really what's happening, but I know there's nothing in the Blockly side of things that seems to have any control over this.

Was there an update that's changed how Blockly imports sprites?

We were made aware of this issue in our Discord. I am currently working on a fix. I will update the Thumby Blockly tutorial when everything is ready to go.

I be sure to let you know.

Hello, after I connect, the TinyTV Mini USB device does not appear on my computer. What happen with this? How can I solved it?

Have you tried other cables? Are you making sure to turn the TV on?

Hi guys, I'm new to this platform. Hello! Anyway, I'm getting a Thumby and I'm trying to ask, what cables do you use to connect the device to your Thumby, and what cable to charge, and I'm also asking what controls do I need to know before using a Thumby?



Thanks, RankXPHO

You should be able to find that information here: https://thumby.us/

Thumby / Re: Is the charger used for my thumby a regular USB cable?

The port on the Thumby is MicroUSB so you need a cable with that connector.

I mean whether you can turn on the TV Mini over it. So when I plug in the usb c cable the TV mini is turned on

That's not possible without a change to the hardware.

Is it possible to activate or watch the TinyTv mini via the USB c connection?

Yes! Use Google Chrome and connect your TV to this page: https://tinytv.us/Streaming/

You'll still have to click the power button and exit USB mode but then you can stream anything from your computer to your TV.
