hi guys, i need help in selecting an attiny chip as i dont understand certain properties.
i am attempting to use the morse library but due to the requirement of hardware multipler? (see below quoted text) i need to find a chip that can handle the library from the attiny selection.
the mega chips such as the 328 is far too big and over powered for this project.
You’ll want to look closer at ATtiny compatibility. I’ve never used one but here’s a Stack Overflow article that seems helpful.
What can't the ATtiny do that the Arduino can? - Electrical Engineering Stack Exchange
It does mention that ATtiny doesn’t have a full hardware-multiply implementation for factors other than 2. I notice in this “morse.cpp” that at least one function calls on floating-point multiply in MorseSender::setWPM(). Might be more spots; that’s the first one I noticed.
Good luck, Barry
ive attatched the morse library as im actually not 100% sure thats the problem, perhaps someone more advanced will know.
