I tried to install the cores that coding badly posted however I believe i'm missing something in the installation because i cant even get the attiny to blink an led now.
And the following folder should contain the Arduino-Tiny core...
C:\Projects\Arduino\hardware\tiny\cores\tiny\
- Open the "boards.txt" file and change both of the "upload.using" entries to
the appropriate value for your setup. Following from the examples above, the
file would be here...C:\Projects\Arduino\hardware\tiny\boards.txt
what dose it want me to put in place of the "upload.using" in the bord.txt file?
Thank you everyone for your help.
