General Discussion / Re: Interfacing 433MHZ LONG RA...

Last post by stanleyadkins - October 02, 2025, 10:06:10 AM

Yes, it is possible to interface the 433 MHz Long Range Radio TinyShield with the EFM8UB1-SLSTK2000A via the SPI interface, as long as the voltage levels are compatible and the SPI configuration matches on both ends (clock polarity, phase, etc.). You'll need to configure the EFM8UB1 as an SPI master and ensure proper wiring (MISO, MOSI, SCK, and CS lines). For development, the preferred IDE would be Silicon Labs' Simplicity Studio, which supports the EFM8 series and allows you to write Embedded C code with full access to device configuration tools, code examples, and debugger support. Make sure to check the TinyShield's documentation for any specific commands or initialization sequences required for communication.

Maybe I'm just not seeing it, but I cannot seem to find a search option for this forum?

I don't want to be the bad etiquette guy who posts question that have already been asked and answered lol.

A TV2 kit would be awesome.  While the prebuilt is very cool, it would be nice to have the option to build your own versions or perhaps 3D print custom cases.

Last post by TomKatt - September 30, 2025, 07:10:35 AM

Recently bought the TV2 and love it !!!  Any chance this version will be available as a kit?  Or where a screen display can be purchased?  I've been Googling around and it seems like the majority of small displays are lower resolution...

Thanks for a great product!  I'm going to start playing with the software now ;-)

Try resetting your device, sometimes it is a software conflict. Or do you have any good solutions?

TinyTV & Tiny Video Player / Re: Tiny TV 2 - AVI Format and...

Last post by parsons3 - September 23, 2025, 10:56:30 AM

When I first bought the TinyTV 2, I assumed any AVI file would play, so I was just as surprised as you when most of my videos didn't work. I also try to keep my Mac secure by downloading only from the App Store, so I completely understand your hesitation. I experimented with a couple of well-reviewed converters from the store, but none of them produced the correct format. In the end, the only reliable method I found was using the official TinyTV Video Converter. It's not ideal, but it seems like the most straightforward solution right now.

Thumby / Thumby won’t turn on

Last post by LouisHollll - September 20, 2025, 06:10:31 PM

I have had my thumby for about 9 months but I don't use it for a while and now it won't turn on. I charged it overnight and the furthest I have got is the logo appears but I can no longer have it show up in the code editor, the furthest I can get is have it make a noise when connecting to windows. 99% of the time it will just light up orange on the bottom and have nothing on the screen.

Ok, So I got it reading the libraries,  But when I click Verify/compile,  I get an error saying that SPI_DIVER_SELECT in SdFatConfig.h must be set to 3.   

But it is.  I found that line, and it IS set to 3. 

I'm totally stumped on this.

TinyDuino Processors & TinyShields / Re: How to Measure TinyZero Ba...

Last post by rafaelakutch - September 17, 2025, 02:01:32 AM

Hi there!

I have a TinyZero connected to a small LiPo battery. I would like to read the current capacity of the battery to the Serial Monitor. Since the board is based off of the Arduino Zero (and by extension, the MKR Zero), I sought to read the value of ADC_BATTERY and convert this value to my voltage reading. The following tutorial shows how to measure battery voltage using an MKR Zero. (https://projecthub.arduino.cc/Arduino_Genuino/mkr-zero-read-battery-voltage-e31f42)
Sprunki Game
When verifying the code for the TinyZero, I receive an error that tells me that ADC_BATTERY is not defined in this scope. However, if I verify the exact same code for an MKR Zero, I receive no compilation errors. Since they use the same processor (SAMD21), wouldn't both boards have an ADC_BATTERY pin, and potentially be able to use ADC_BATTERY the same way?

Thank you for any help!

ADC_BATTERY is not a SAMD21 hardware feature but a board variant alias. MKR boards define ADC_BATTERY in their variant so analogRead(ADC_BATTERY) works. TinyZero's variant does not expose ADC_BATTERY so the symbol is undefined. Fix it by checking the TinyZero schematic to find the ADC pin used for battery sense and then use analogRead(thatPin) or add a simple resistor divider to a free analog pin and read that. See MKR variant examples and TinyZero docs for the pin/schematic references.
