I have been using the beta IDE for a while now, and I prefer it to the non-beta version. There is a problem though - the cores I have for ATtiny45/85 do not work with it. The solution? To write one!
I have attached a .zip file to the post, which contains the core for the ATtiny85. The code I tested compiles perfectly with it under the new beta IDE, however I broke my ATtiny some time ago, so I cannot test it.
For instructions on using it, I have to reconmend the HLT wiki: http://hlt.media.mit.edu/?p=1229
I used the boards.txt file, only altered, for the new core, so the pin layout will be identical to that shown in the wiki.
If there is someone using the beta IDE with a tiny85 lying around, I would be hugely greatful if they could test it for me
. I am planning on trying to make some more cores soon, as well as altering the one presented here some more.
P.S. there is no bootloader included in the file for several reasons:
1)It would take up too much memory,
2)The ATtiny45/85 has no UART, so it would not be at all beneficial,
3)I don't know how to write one.
Also, upload is via arduino as ISP, just like it shows in the HLT wiki.
