+ * #include "mbed.h"
+ * #include "SerialGraphicLCD.h"
+ * 
+ * SerialGraphicLCD lcd(p26, p25);
+ * 
+ * int main() {

+ *   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");
