   * This is just a ATTINY45-20PU on a breadboard with a USB/Serial adapter and a
   * LED connected at pin #5 (PB0/OC0A). No crystal.
   *
   * The serial communication uses 1 wire for RX/TX, AVR pin #2 connected to the
   * RXD pin of the serial adapter, and a 1k resistor is connected between the RXD
   * and TXD pins (it could be replaced by a diode, Schottky preferably).
   *
   *     TINY45 ->  2 : RXD <- Serial Adapter
   *		    : TXD
   *		  1 : DTR
   *		  4 : GND
   *		  8 : VCC
   *
   * To install Diabolo with avrdude/usbasp:
   *
   *	USBASP -> 1  MOSI  5 <- TINY45
   *		  2  VCC   8
   *		  4  GND   4
   *		  5  RST   1
   *		  7  SCK   7
   *		  9  MISO  6
