Analogue and digital input and output

initialisation sequence.

sends an analogue signal (-10V -> 10V) to channel 0 or 1.

reads the tension at channels 0 to 7. Channels 0 and 1 are reserved for the CJC and the thermocouple readout.

returns the temperature as measured by a thermocouple (tc) or a resistor (pt).

stores the values measured at the specified channels into a file in the speficied time interval. Up to 4 channels can be logged simultanuously. The temperature can be logged using channel 1.

stops logging the data.
