New project: Reading temperature sensor DS18B20 via Commodore 64 and sending data over #rs232 to #pc to plot a graph in #python.

@Wintermute_BBS Sensor works with 1-wire protocol and it is connected to single gpio pin on user port. 6526 serial (rs232) is used to send data from c64 to pc.
@Wintermute_BBS I wrote a 1-wire communication protocol (in assembly) to make it work. (the sensor)
@josipretrobits Nice project!! I see you are connecting via the userport, so I suppose you use the 6526 for serial I/O? what baudrate does the sensor operate at?
