TinyTV & Tiny Video Player / Tiny TV 2: Removable disc name not showing up on Mac

« Last post by backdrifts on Today at 01:26:48 AM »

Hello,
 

To preface, I tried to change the 'Preferences' in Finder, but it did not make a difference.

I am not able to see the removable disc when I check Disc Utility. I have a new USB-C cord I just purchased. I have the files downloaded and converted, I cannot drag them into the Tiny Tv 2 application.

I just needed some troubleshooting advice.

I am using macOS Monterey (Version 12.7.4).

Cheers!

I didn't initially find this page until after I posted. I hope this covers everything I was/am looking for. If you have further suggestions though please comment.

TinyTV & Tiny Video Player / Reformatting (programming) a TinyScreen+ to a TinyTV

« Last post by 1DoctorNosFeraTu on April 29, 2024, 03:40:04 PM »

Hello Tiny Circuts users/enthusiasts,

I'm new to this whole thing so if my question is inane, it probably is. Per subject line I'd like to reformat/reprogram a TinyScreen+ to work as a TinyTV.

Context: I had recently bought the DIY TinyTV Kit and in assembling it had cracked and damaged the TinyScreen+ that came with the kit. I ordered a new TinyScreen+ thinking it was only a matter of replacing the damaged component. Today I replaced the screen except now I cannot seem to get it to read from the SD card, it will only boot up the Flappy Birdz game. Again, I am new to this and I cannot seem to connect to the TinyScreen+ from my PC to investigate or try to replace the program with the TinyTV code.

Your wisdom and advice are much appreciated because I could not find adequate answers elsewhere in the forum or tutorials. Thank you.

Regards,
1DoctorNosFeraTu

Has the apps. LMK if you can't get them and I can try to upload them somewhere.

TinyTV & Tiny Video Player / Slow transfer speeds over USB

« Last post by domukin on April 26, 2024, 12:28:10 AM »

I just got a Tiny TV 2 and wanted to make sure this was normal... Transfer speeds over USB are about 700 KB/s.

I've tried different USB cables and different ports on my PC.

I also updated the firmware on the device. Seems to work fine.

TinyDuino Processors & TinyShields / Re: lithium battery management on TinyZero

« Last post by villagetunic on April 14, 2024, 11:54:58 PM »

In practical terms, what does 'lithium battery management' mean for the TinyZero. Does it turn off so the battery does not go below a certain voltage? Also, does the lithium battery charge when the tinyzero is plugged in via the usb cable? basketball stars

Any help/insight appreciated, and thanks in advance to anyone who replies 

The batteries themselves have circuitry that shuts off their output when the voltage gets low enough.

The battery management on the TinyZero is just the charging circuit. When not plugged in, the TinyZero will draw power from the battery as long as the battery voltage doesn't get too low and the battery shuts off its output. When plugged in, the TinyZero draws power from USB while at the same time the USB is used to charge the battery.

I'm also experiencing this difficulty. I'm not sure how to solve it. And I got my answer from you. Thank you, I've solved it.

TinyDuino Processors & TinyShields / SmallScreen Smart Watch Codec Problems

« Last post by villagetunic on April 14, 2024, 11:44:31 PM »

Farewell, everyone, I'm somewhat inexperienced with this type of programming, and I'm struggling to upload a sketch onto the watch in order to proceed. Drivers, updates, and device recognition have been the least difficult things thus far, but the integrated development environment (IDE) is giving me a headache, gorilla tag so I'm not sure what to do next. Here is a screenshot showing the faults. What am I not seeing? Does any library have an error? Nothing has worked since I went to github to grab the new library files.

Could you please lend me a hand? I'm very unprepared and I simply wanted to show myself that I could pull this off.

Thumby / Thumby Freezes / crashes when i use dpad up

« Last post by SpamToast on April 12, 2024, 12:27:47 PM »

Hey everyone, i did not find any Threads that describe my Issue so ill open one up.
I have a really weird problem with my Thumby. In ALL games and even the Menu my Thumby freezes as i press the Up button.
Not everytime, sometimes i can play a minute or two but definetaly to often... i can't even play Tennis till i lose even if i want to except if i do NOT use up arrow
It only happens using this specific Button. Did anyone ever had that?
I used the format function in the Web editor, i updated it, i even installed the firmware manually.
i dont know what to do and hope for help.

new Question: Is it possible to open the Shell of Thumby without breaking it? looks like its glued and would break. maybe somethin ist stuck inside and shorts the device as i press the up button?

Thumby / Re: Porting micropython thumby libraries to C?

« Last post by Jason on April 05, 2024, 10:00:30 AM »

I'm starting to look into how i want to make games for the thumby but I realized there's a lot of micropython only functionality like saves and sprites. (I'm addicted to C).

Could someone give me a few pointers and how to reimplement the micropython stuff in C? Here's some of the specific stuff I was trying to figure out:

Where in the micropython fork should I be looking for thumby specific stuff? there's a couple of branches and files, is it all just in rp2? Whats actually loaded on the thumby? there's probably something in the code editor repo i haven't found yet...

For hardware interaction I definitely need to figure out how to load littlefs or whatever filesystem abstraction micropython is using. Is there a specific place in the repo that deals with that? I might just try loading up a littlefs C library..

Also is there any other hardware interactions that C is missing besides the filesystem? I see a sprite system but maybe that's just a nice wrapper around loading sprites and writing them to the buffer.

(anyhow thanks for reading)

Hi,

We don't actually use a fork of MicroPython for the Thumby firmware, we use the vanilla/regular version from the website (1.19.1: https://micropython.org/download/RPI_PICO/). The version we have on our GitHub is mostly for the emulator and testing.

Although we don't build our own MicroPython, I am very familiar with how it works. If you want to use littlefs from C then you can use version that gets pulled in from MicroPython itself (lib/littlefs/lfs2.h). This isn't exactly simple though as you will have to reimplement the prog/sync/erase functions for the RP2040. The documentation on how to use littlefs is in this header: https://github.com/littlefs-project/littlefs/blob/master/lfs.h

There are a couple of different hardware interactions that would have to be implmented in C:

• Init and sending data to the display
• Buttons
• Sound

The sprite portion of the Thumby library just handles pulling data from a sprite and then copying it into the framebuffer at a location. It also does some simple animation type stuff.
