Driver Formats & Routines

The ADC-10, ADC-12, ADC-40 and ADC-42 are supplied with driver routines that you

can build into your own programs. Drivers are provided for the following operating

systems:

Windows XP

Windows Vista

Linux

Once you have installed the software, the Examples subdirectory contains the drivers

and a selection of examples of how to use the drivers. It also contains a copy of this

help file in text format.

The driver routine is supplied as Dynamic Link Libraries for Windows.

The Windows DLLs can be used with any programming language or application that

can interface with DLLs- for example, C, Delphi, Visual Basic, Excel, Labview, etc. The

Examples directory contains example programs for several popular programming

languages or applications: some of these examples are fairly simple, but the C console

mode example, adc10con.c, shows how to use all facilities in the driver.

The driver is capable of supporting up to three parallel port units (one each on LPT1,

LPT2 and LPT3), and up to four Pico USB parallel port units. The units can be any

mixture of ADC-10, ADC-12, ADC-40 and ADC-42.

The following table specifies the function of each of the routines in the Windows

drivers:

Routine

Function

adc10_get_driver_version

Check that this is the correct driver

adc10_open_unit

Open the driver to use a specified parallel port

adc10_set_unit

Select which ADC-10 unit to use

adc10_close_unit

Close the specified printer port

adc10_get_value

a single reading

adc10_get_value_and_time

a single reading and the time

adc10_set_trigger

Set a trigger event

adc10_set_interval

the time interval for the next call to adc10_get_values,

or adc10_get_times_and_values

adc10_is_streaming

Check whether the device supports streaming (USB

only)

adc10_run

Start the unit recording

adc10_ready

Check whether the data recording is completed

adc10_stop

Abort data collection

adc10_get_values

a block of readings at fixed intervals

adc10_get_times_and_values

Get a block of readings and their times, at fixed

intervals

adc10_get_unit_info

Get information about an ADC10 unit

The driver offers the following facilities:

specify the printer port or USB parallel port that is connected to the ADC

take a single reading

specify a trigger event (only available in block mode)

collect a block of samples at fixed time intervals
