adc100_is_streaming

short adc100_is_streaming (void)

This routine can be used to determine whether the device is capable of supporting

streaming. If so, it will return TRUE (1). A streaming device collects data in an

asynchronous manner. USB devices generally support streaming, whereas parallel

port devices do not.

Arguments:

none

Returns:

TRUE if the device supports streaming

3.3.8

adc100_run

void adc100_run (

unsigned long no_of_values,

unsigned short method)

This routine starts a streaming unit collecting data It collects readings at intervals

and from channels specified in the most recent adc100_set_interval call. For

non-streaming devices, this function has no effect.

Arguments:

no_of_values

- the number of samples that are to be collected

method

- the data collection method:

BM_SINGLE (0) - collect a single block and stop

BM_WINDOW (1) - collect a sequence of overlapping

blocks

BM_STREAM (2) - collect a continuous stream of data

Returns:

1 2 ... 8 9 10 11 12 13 14 15 16 17 18 ... 24 25
