I am attempting to upload a sketch that is currently running on a Nano to a ATTiny85 board. So far, no success. I have installed the necessary drivers for the ATTiny85 board in the Arduino IDE software, and uploaded a test sketch (blink), which does work. So the board is OK. But when uploading the desired sketch to the ATTiny, it won't finish compiling. This sketch does work (it is for a digital clock with custom display). Is it too large to fit on the ATTiny85? Or does it need to be modified? Any assistance would be appreciated.
