Hello Forum
Running Window 11 and the Arduino IDE 2.0.4 and using
ATtiny85
https://www.sparkfun.com/products/9378
with
a SparkFun Tiny AVR Programmer
https://www.sparkfun.com/products/11801
Using the tutorial at
http://highlowtech.org/?p=1695
the
At Prefences the URL
https://raw.githubusercontent.com/d...ds-manager/package_damellis_attiny_index.json
was added to tthe Additional Board Manager URL textbox
Then at the Boards Manager in Tools > Board > Board Manager the attiny by Davos A. Mellis was installed.
Then at Tools > Board > ATtiny > AtTiny/25/45/85 was chosen
The 8 Mhz internal clock was chosen and the Programmer was set as USBTinyISP.

But the Arduino IDE at the bottom right says "ATTiny/25/45/85 not connected.

And the Tools > Port option is greyed out.

At Windows Device Manager when the SparkFun Tiny AVR Programmer (with a ATtiny 85 on the board)
is plugged in, under Other Devices a listing for FabISP can be seen which disappears the board is unplugged.

Similarly, and to eliminate the cable and the USB port as points of failure,
when an Arduino Uno is hooked up to the PC the status bar at the lower right
in the Arduino IDE says "Arduino Uno on COM9" and the is a listing in the Device Manager
Ports (COM & LPT) > Arduino Un0 (COM9) which disappears when the board is disconnected.


It is surmised that because the Device Manager sees FabISP
and the the FabISP is not listed in the Tools > Pro0grammer options that
this the failure.

Programmer options tried: Arduino as ASP, ArduinoISP, AVRISP, AVRISPmkll, USBASP, and
USBtinyISP.


How can I get the IDE to recognize the Tiny AVR Programmer?

Thanks.

Did you load the Win11 driver for the programmer? Then did you "burn bootloader" on the ATTiny85? Then did you "upload using programmer" rather than just "upload"?

 

I browsed some of the comments from users and apparently, success depends on what operating system you are using and which version of the Arduino software. Have you tried the GitHub blog? They may be able to help.

There is no need to burn a boot loader on the ATTiny85 when using the Sparkfun programmer. Windows 10 (I don’t use Win 11) automatically installs the programmer drivers when the programmer is connected without a ATTiny 45 or 85 is inserted. You do have to install the board support in the Arduino IDE.

Why are you using that tutorial? The tutorial on the Sparkfun site worked perfectly well for me. Since it is a Sparkfun product, I would try their tutorial. See if it works better for you.

 

I made a programmer out of a cheap clone Arduino nano. It works really well on all platforms and all the recent Arduino software. I have programmed DIP Tiny85s and ATmega328s. I can post the details if you are interested.

If you don't burn the bootloader, are you not limited for choice of clock frequency to 1MHz?

I don’t know about that. But the programmer he purchased does not use require a boot loader, so it might be limited anyhow unless he purchases/makes another programmer.
