Example

var oled = new OledDisplay(); 
var str = "OLED Display"; 
var strw = oled.stringWidth(str); 
var strh = oled.stringHeight(str); 
var strx = (oled.width() - strw) / 2;
var stry = (oled.height() / 2) + strh;
oled.clear(); 
oled.drawRect(0, 0, oled.width()-1, oled.height()-1);
oled.drawString(strx, stry, str);

API

OledDisplay();  // always connect to PORT_4E
startBuffer(); // subsequent draws will be buffered until flushBuffer() is called
flushBuffer(); // flush all buffered draws to screen
clear(); // clear screen
setColor(color); // COLOR_WHITE, COLOR_BLACK
setFont(font); // FONT_NORMAL, FONT_SMALL, FONT_LARGE, FONT_NORMAL_BOLD, FONT_SYMBOL
width(); // get width of screen (128)
height(); // get height of screen (64)
stringWidth(string); // get pixel width of string in current font
stringHeight(string); // get pixel height of string in current font 
drawPixel(x, y); 
drawLine(x1, y1, x2, y2); 
drawRect(x1, y1, width, height, filled = false); 
drawEllipse(x, y, rx, ry, filled = false); 
drawString(x, y, string); // Note: y is baseline of text
