ATtiny85 Port Greyed Out 230423

[AllenPitts]

Hello ETO Forum,
Have read several articles on installing support for the ATtiny
including
ATtiny85 microcontroller tutorials, Part 2: Working with ATtiny85
Still having issues with getting the IDE to recognize the programmer.

Running Window 11 and the Arduino IDE 2.0.4 and using
ATtiny85

AVR 8 Pin 20MHz 8K 4A/D - ATtiny85 - COM-09378 - SparkFun Electronics

The ATtiny45 and 85 are a couple of really cool little MCUs but did you know you can program them in Arduino? That's right, now you can shrink your Arduino

Using the tutorial at

Programming an ATtiny w/ Arduino 1.6 (or 1.0)

This tutorial shows you how to program an ATtiny45, ATtiny85, ATtiny44 or ATtiny84 microcontroller using the Arduino software. These are small, cheap ($2-3) microcontrollers that are convenient for…

In the Arduino IDE at Preferences the URL

https://raw.githubusercontent.com/damellis/attiny/ide-1.6.x-boards-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 S rkFun 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.

I tired numerous other solutions but ultimately used a web site
solution just using a Nano board or a Uno board. There are a number
of sites doing this.

Other times, boards, always having to try various drivers. Often rebooting
PC each time.

Open source solutions, which I am a fan of, are rarely ever supported like an OEMs
solution, its the price we pay for the open source experience. We get something for free,
until we account for the large amounts of time spent to resolve stuff like this.

Another possibility is the quality of the cable, if cabling the programmer to PC versus
direct plugin of programmer, can be a problem. I googled "FabISP exclamation point in
device manager" and got a number of fixes on web, not all aimed directly at FabISP, more
general problems.

Sparkfun offer any help ?


Regards, Dana.

Have you had a look a the Sparkfun driver package?

Missing driver I think.
