  • Can I use this library with an ATtiny85?

    All the pins can be changed from the default values you just need to set them when you call the constructor. Look here: https://github.com/carlosefr/pcd8544/blob/6555ce575565724afbf9bc84d341082d2059f99b/PCD8544.h#L65

    I have a PCD8544 LCD screen (NOKIA 5110) and wanted to use this library with the ATtiny85. I am trying to print "Hello World" on the screen with the included example but it's not working. It works when I use my Arduino, but not with the ATtiny. I tried changing the default pins in the PCD8544.h document in the library to match the ATiny pins, but it didn't work. I'm new to Arduino, so if someone could explain to me why the library is not working that would be nice.
