I have just installed VM under VS in Win 10 64 and wish to install the ATtiny support from https://github.com/arduino/Arduino/wiki/Unofficial-list-of-3rd-party-boards-supp....
I wanted to use Visual Micro Explorer as suggested in the VM instructions rather than copying the files to the Arduino directory etc.
in "Configure ide locations" in "Optional additional boards....................." I placed: http://drazzy.com/package_drazzy.com_index.json ;
I select OK and go to Visual Micro Explorer and see two ATtiny boards listed under "Board Package Auto....."
I select the one I want which then becomes grey but nothing else happens and the ATtiny board option is not available in the drop down list.
Have I missed something, advice please.

I already tried Rescan a couple of times but although the ATtiny I want is grey in "Board Package Auto-Discovery" It still does not appear in "Board Package Installer"
I have Arduino 1.6.12
Jim

In Tools - Options - Visual Micro - General - Version= 1.1609.4
Interestingly when I look in Visual Micro Explorer, I have "Installed Arduino AVR Boards Version 1.6.14".
I installed this from VME as it was shown against Available updates but if I run the Arduino Dev Environment, in help its says its 1.6.12
Jim

The visual micro version is found in "visual studio > Tools>Extensions and Updates>Arduino Ide for Visual studio."

by the way

The arduino ide version doesn't have to be the same as the avr version but you should not install avr via board manager. always leave as the one installed with the arduino ide. this means that you have a known config and when you update the arduino ide it will also update the avr

Sorry I just checked. I thought you had installed avr via board manager which installs hardware defs to the c:\users\[name]\appdata\local\arduino15\packages folder not the ide. BUT the 1.6.12 ide is installed with 1.6.14 avr in the ide\hardware folder so that's confusing. 

Your setup is correct and on latest visual micro version.

Try adding the json url to the arduino ide and using that board manager or let me have a list of folder names in c:\users\[name]\appdata\local\arduino15\packages and a list of .json file names in c:\users\[name]\appdata\local\arduino15. 

Thanks

Ok, I try to see what would cause it not to show. Thanks
