# HISTORY:
I searched a lot on the internet but I couldn't find a single library for my 128x64 LCD display (I was only finding OLED ones), until I found this czech site, with a working code for it. The problem is, that it was in czech.
So, I did my best to translate it and improve its performance and add a few functionalities.
# THE LIBRARY:
The library is working, most is in english, and almost everything you can understand.
The first part of the code, as the original code, is a demonstration of its working. Then are the functions you can use.
There is also a python3 version of the library that I ported, but as I tested in August of 2017, it was something like 25~30% slower than the python2 version. This surely doesn't apply anymore (2020+).
## New functions:
#### drawGenericLine
The original code only had drawHorizontal and vertical lines, so I added this, that draws from a coord to another.
#### drawCircle
Draws a circle!
#### drawRadiusLine
Draws a line like a clock hand, where you enter the initial coordinate, the angle in degrees and the radius (the size of the line)
#### printString3x5
The 12864 LCD have a built-in display text function, but the chars are big (16x8 pixels each char, max of 20x4 chars in screen).
The original version of this code had a smaller version of text (8x8 pixels each char), but for my purposes they were still big.
So I coded this function, which prints small chars, 3x5 pixels each.
