ATtiny85 Port Greyed Out 230423

Hello SparkFun 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 Arduino IDE menu File > Preferences the URL

https://raw.githubusercontent.com/damel … index.json

was added to the 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 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 FabISP is not listed in the Tools > Pro0grammer options that

this the failure.

Programmer options tried: Arduino as ASP, ArduinoISP, AVRISP,

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

Thanks.

Hello, is the USBTinyISP programmer properly installed in your computer? The PORT option is usually grey when the driver software is missing or it’s a bad USB cable.
