But are you using a transistor of some kind? A 220 ohm resistor won't give you much range.
Ok, so you don't have to worry about getting all the key definitions in ram. But I think I will convert the Technics test code into a general-purpose raw transmitter that doesn't require a library - for 328P Arduinos - in case it would be useful to some.
Right. But how were you able to run the raw capture sketch I wrote? It was 328P as well.
Well it sounds like you're in good shape to finish the project.
