Forgive my ignorance, but I am trying to lighten a library so that I can fit it onto an Attiny85.
I am trying to employ LCD3wire (new liquid crystal library) using LiquidCrystal_SR -- so the Attiny is coupled with a 74HC595 shift register. The trouble is, the LiquidCrystal_SR (shift register) portion is already upwards of 6000 bytes by itself when compiled. I'm also running into issues compiling for the Attiny85, but perhaps I'll leave that for another thread.
I instead tried to use the LiquidCrystal595 library which is much lighter (2000 bytes). Unfortunately I wasn't able to get my hardware working with this code using an HH4870 16x 2 LCD with a Leonardo board. I spent a good part of my night trying to figure that out, but as far as I could tell, I had everything wired correctly, and only got gibberish on the display.
Thus, I'm reluctantly turning here for help. I don't absolutely have to use an Attiny85 for this project, but I would like to if possible.
