…..50

If you are not using a channel, we recommend setting the range to ±20V. This prevents noise from the

unconnected channel interfering with the channel that you are using.

adc100_get_value

PREF 1 short PREF2 adc100_get_value (short channel);

This routine reads the current value of one channel. Depending on your computer, it will take approx 20µs to take

one reading.

channel 0 - channel A

1 - channel B

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 asynchronously. USB devices generally support

streaming, whereas parallel port devices do not.

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.

no_of_values the number of samples to collect

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

adc100_ready

short adc100_ready (void)

This routine indicates whether a streaming device has completed its data collection. It returns TRUE if the

device is ready to transfer data. For non-streaming devices, it always return TRUE.

adc100_stop

void adc100_stop (void)

This function cancels any pending request for data from a streaming device. It has no effect for non-

streaming devices.
