Adding ATtiny library to IDE 1.8.3m (Sparkfun AVR programmer)

I download the most recent IDE to my computer and I am trying to add the ATtiny addon to Arduino 1.8.3 so that the ATtiny85 board will show up on the list.

I am using the Tiny AVR programmer from Sparkfun.

I googled installing the ATtiny addon but couldn't find any specifics.

What am I missing?

Your assistance is much appreciated!!

I recommend using this one:

Full usage and installation instructions are at the link above.

Thanks for the namedrop - yeah; you can install my core either via board manager or manually, see the installation page linked from the github docs.

The TinyAVR programmer is a USBTinyISP clone. You may need to install drivers as detailed on the Sparkfun page.

Thank you for your advice. I will try it later on this evening. :slight_smile:

I recommend using this one:
GitHub - SpenceKonde/ATTinyCore: Arduino core for ATtiny 1634, 828, x313, x4, x41, x5, x61, x7 and x8
Full usage and installation instructions are at the link above.

I wnt to this page but can't, easily, see anything that tells me how or where to find the info about how to install the ATTiny85 addon for V1.8.1 on my Win7 PC so I can use Arduino to program these 3 chips?????

Really? It's the first link on that page "Installation":

Follow the instructions under "Boards Manager Installation" and you'll be set to go!
