The meanings of the terms in the .DDS file are as follows:
[Scale1]
A unique number, from 1 to 99, to identify this entry. (Pico-created numbers are
from 100 upwards.)
Resistor=1
The ID resistor value in kiloohms. In this example "1" represents 1k, "2.2"
represents 2k2 and so on.
For external sensors, this resistor should be fitted in the sensor. You must use one
of the following resistors: 1k0, 2k2, 3k3, 5k6, 7k5 or 10k. The resistor must be 1%
tolerance or better.
For internal sensors, use the following 'virtual' resistor values:
1
Sound Waveform
2
Sound Level
3
Voltage
4
Resistance
5
pH
6
Temperature
7
Light
