I'm working on a project with a Digispark ATTiny85, that performs keystrokes using the DigisparkKeyboard library (https://github.com/digistump/DigisparkArduinoIntegration/tree/master/libraries/DigisparkKeyboard). Besides the DigiKeyboard, I also import EEPROM.h.
My own code is only about 150 lines, I've cut down the size following a number of online guides, trying to avoid larger data types and so on. The Digispark is limited to ~6kB and the imported DigiKeyboard library takes up a little more that 5.4kB. In total the compiled project takes up about 7kB, which exceeds the boards capacity.
From the DigiKeyboard library I only use
DigiKeyboard.print() (with about only ten different characters). So I assume there is a lot of unused code I could remove, but I don't know how to approach this. I use Visual Studio Code and PlatformIO.
How could I reduce the size of the used DigisparkKeyboard library?
