These are personal notes that may help you. Read carefully, as some parts may be disjointed!
Key points:
- Install the compilers first (using the same principle). I made these notes before finding this out!
- Then install the IDE.
- If you install in reverse order, run the IDE un-install, default settings, then re-install after. Failing to do may cause the IDE to crash on start.
General points:
- My testing was as far as a simple project for an ATTiny441 producing a valid hex file.
- Using a programmer directly from the IDE is untested.
