Agreed, I'm 101% convinced! Thanks for the QED

Answering your earlier question: my own sketch (working on UNO) failed on compile to ATTiny88. Looking at the verbose report it seems to be down to RTClib somehow? Obscure to me. I'll paste the full report .

I also note a warning about low memory. While not the cause of failure, that may well prompt me to abandon the present time-consuming quest. And instead just restrict usage of my four Tiny boards to relatively trivial sketches.

I'll try reproducing your steps later today.

There is nothing surprising in that - the Tiny family controllers doesn't have a I2c interface. It use an USI instead.
Therefore the Wire library in the code is just a emulation, which may not be fully compatible between platforms.
Another problem - If the library code uses low-level i2c methods, this library will not work on Tiny.

Terrypin · April 26, 2024, 10:37am

Thanks. Looks like another reason to "...abandon the present time-consuming quest. And instead just restrict usage of my four Tiny boards to relatively trivial sketches."

Seems that I can get 'LCD only' sketches running, so at least I have a limited debugging facility, but even that appears inconsistent.

gfvalvo · April 26, 2024, 10:57am

It looks like your core and library installation is still a mess. Why do you have a Hardware core in your SKETCHES folder???

Using library Wire at version 2.0.0 in folder: C:\Users\terry\Dropbox\Electronics\Arduino\SKETCHES\Hardware\ATTinyCore\avr\libraries\Wire

Despite that, it actually did compile (although perhaps incorrectly because of your installation mess). It failed to upload to the board:

Problem uploading to board.  See https://support.arduino.cc/hc/en-us/sections/360003198300 for suggestions.

So, you likely have a programmer problem too.

Post the full code you tried to compile. I'll see if the log looks more promising on my installation. Specify exactly the libraries you're using, including version. Provide either a GitHub link or a screen shot of the library in Arduino's Library Manager.

Terrypin · April 26, 2024, 12:59pm

Ok thanks. I’m away from PC but checking SKETCHES\libraries on my iPhone there is no Wire entry. As discussed up thread I deleted it a few days ago.

Presumably a folder ‘libraries-30Jan’ where I kept some old backup is ignored?

gfvalvo · April 26, 2024, 1:05pm

The compiler sure sees a hardware core in your SKETCHES folder. It doesn't belong there!!!

At this point, I'll believe the compiler not your iPhone.

Terrypin · April 26, 2024, 4:40pm

My \libraries folder is here, as configured in IDE > File > Preferences > Settings > Sketchbook location:
C:\Users\terry\Dropbox\Electronics\Arduino\SKETCHES\libraries

Not
C:\Users\terry\Dropbox\Electronics\Arduino\SKETCHES\

gfvalvo · April 26, 2024, 4:44pm

Please answer my question .... why do you have a Hardware Core in your Sketchbook folder?

gfvalvo · April 26, 2024, 5:26pm

I can say with confidence that @Terrypin is doing neither. I've never seen a core installed via the Board Manager end up there.

Terrypin · April 26, 2024, 6:48pm

It's not in my 'Sketchbook folder', as I showed you in post #31.

The core you described from the error report was :
C:\Users\terry\Dropbox\Electronics\Arduino\SKETCHES\Hardware\ATTinyCore\avr\libraries\Wire .
I didn't create it or any of its subfolders or files.

Where are the cores you installed located?

gfvalvo · April 26, 2024, 6:51pm

It's certainly under it:
C:\Users\terry\Dropbox\Electronics\Arduino\SKETCHES\Hardware\ATTinyCore\avr\libraries\Wire

See Post #23.

Terrypin · April 26, 2024, 6:56pm

No, it's not, look again! Once more, see my post #31. Are you perhaps confused by the fact that the string 'SKETCHES' appears more than once on my PC?

gfvalvo · April 26, 2024, 7:03pm

Could be that I'm quite confused. I see this:
C:\Users\terry\Dropbox\Electronics\Arduino\SKETCHES
and this:
C:\Users\terry\Dropbox\Electronics\Arduino\SKETCHES\Hardware\ATTinyCore\avr\libraries\Wire

So if the former is your sketches folder as selected in preferences, then latter is under it. @Delta_G, says that's OK. But it certainly seemed odd for a core installed via Board Manager.

Terrypin · April 26, 2024, 7:16pm

Yes, on seeing @Delta_G 's feedback I was a tad resassured that it wasn't just down to me! Can't remember the details (some months ago), but I did carefully follow the instructions on installing the core. And that's where it ended up. Clearly different in your case.

Terrypin · April 26, 2024, 7:27pm

Thanks, that was certainly the guidance I recall - although I'm still unsure which option I took. I think I tried one, probably the Boards Manager, hit problems and successfully used the other.

LarryD · April 26, 2024, 7:31pm

Sorry but I have to say, an Ultrasonic Cleaner might be your best friend.

Terrypin · April 26, 2024, 7:50pm

Should I remove the Arduino boards first?

Reckon that blue breadboard must be at least 25 years old. Guess it's my age - I hate throwing stuff away.

LarryD · April 26, 2024, 9:26pm

The next time the breadboards are free, remove all components and clean in the cleaner.
Suggest 50% IPA, put breadboards in a plastic bag (to conserve IPA), emergency in 50° water.
Rinse with water, blow dry.

I still have my school day SK-10 breadboards from 1977.

westfw · April 27, 2024, 12:44am

The "new" TIny's (TinyAVR-0,1,2 aka "megaTiny" or "xTiny") (like ATtiny3217) , and avr-dd, avr-ea, etc (AVR16dd28) are much more capable. And generally cheaper, too.
I'm not sure if anyone has ported over the VUSB stuff, though.
