Uno as ISP to program ATTiny85

Development Tools IDE 1.x
1

Hi Guys

Just ran into a puzzle (well it is for me!)

I normally program ATTiny85s using a UNO as ISP with a programming shield (just a shield to replicate the usual UNO to ATTiny wiring). I've never had any real problems using IDE 1.04 after modifying the boards.txt file (part of the zip download here: http://hlt.media.mit.edu/?p=1695 ) and locating it in the recommended place (Hardware folder in the Arduino sketchbook folder). The ATTiny85 option for board choice was always readily available, amongst others) from the Tools/Board dropdown menu in the IDE.

Problem is, ever since I upgraded to IDE 1.5.2, I only get the default board options in the Tools/Board dropdown menu, and no amount of fiddling with file locations will change that. Anyone know if the Variants folder and boards.txt file need moving elsewhere? If not, any ideas as to why the contents of the board.txt file don't get added to the boards list?

I think the install instructions call for the files to be installed in:

Arduino/hardware/attiny/boards.txt
Arduino/hardware/attiny/variants/tiny8/pins_arduino.h
Arduino/hardware/attiny/variants/tiny14/pins_arduino.h

I think it's the attiny folder that is different.

I would recommend staying with IDE 1.0.x for now. It will require more than just file location changes for IDE 1.5.x. IDE 1.5.x is still a work in progress, mainly for the Due.

Thanks for the advice guys. For now I've reverted to 1.0.4 and, as expected, its all good now.
I'll wait until the file location glitch is sorted. No big deal, 1.5.2 didn't give me anything extra I needed anyway :slight_smile:

@johnwasser - yep, those locations are where I've got my files located.
