/** Interface to the Sparkfun Serial Graphic LCD, LCD-09351; and Graphic 
 * LCD Serial Backpack, LCD-09352. Derived class from Serial so that you
 * can conveniently printf(), putc(), etc to the display.
 * 
 * Example:
 * @code
 * #include "mbed.h"
 * #include "SerialGraphicLCD.h"
 * 
 * SerialGraphicLCD lcd(p26, p25);
 * 
 * int main() {
 *   lcd.baud(115200); // default baud rate
 *   while (1) {
 *      lcd.clear();
 *      lcd.rect(3, 3, 20, 20);
 *      lcd.printf("Hello World!");
 *      lcd.pixel(14, 35, true);
 *      lcd.pixel(16, 36, true);
 *      lcd.pixel(18, 37, true);
 *      lcd.pos(5, 30);
 *      lcd.printf("Hi");
 *      lcd.circle(50, 20, 20, true);
 *      lcd.pos(50, 20);
 *      lcd.printf("Howdy");
 *      lcd.line(0, 0, 25, 25, true);
 *      wait(2);
 *   }
