2.2

Scaling

The ADC-100 and ADC-101 are 12-bit analog to digital converters. This means that

they produce values in the range 0 to 4095 to represent the currently selected input

voltage range. To convert from ADC readings to volts, you should subtract half of the

2048, multiply by the currently selected voltage range and divide by 2048. Thus, on

the 5 V range, an ADC reading of 3135 represents (3135-2048) x 5 / 2048 = 2.654

volts.

2.3

Streaming

If a device is connected to a Pico USB parallel port, data is collected in an

asynchronous manner, without any intervention from the PC. This gives considerably

more reliable data collection, and sampling does not interfere with the operation of

the your computer.

When collecting data from a streaming device using the drivers, three modes are

available:

BM_SINGLE

Collect a single block of data and exit

BM_WINDOW

Collect a series of overlapping blocks of data

BM_STREAM

Collect a continuous stream of data.
