PREF1 unsigned long PREF2 adc100_get_combined_values (
UNS16 channel,
COMBINATION_METHOD mode, /* Combination modes (CM_XXX) */
UNS16 no_of_readings )
This routine takes a set of readings from the specified channel, at full speed, and
returns either the minimum, maximum, average or sum of the set of readings.
Arguments:
channel
0
- channel A
1
- channel B
mode
0 - average
1 - minimum
2 - maximum
3 - sum
no_of_readings
- the number of readings to take
Returns:
3.3.17 adc100_apply_fix
PREF1 void PREF2 adc100_apply_fix (
unsigned int fix,
unsigned int value )
Some PCs have non-Centronics-compliant parallel ports. The ADC-100 requires a
small grey adapter (supplied with the unit) between the ADC-100 and the parallel
cable. This driver usually auto-detects the adapter, but occasionally you will need to
use this function to force the adapter into being used.
Arguments:
fix
- adapter detect
value
0 - auto-detect adapter
1 - force no adapter
2 - force use of adapter
Returns:
none
Note: An alternative to using this routine is to add an entry to the
win.ini
file
(usually located in
C:\WINDOWS\
), add the following lines:
[ADC100]
UseAdapter=Yes
UseAdapter
can be
Yes, No
or
Auto
(
Auto
is the default if these lines are not
present in the
win.ini
file)
