Arguments
Returns
5.2.13 ps3000_stop
void ps3000_stop (

Returns
5.2.14 ps3000_get_values
long ps3000_get_values(
This function is used to get values. This function does nothing if ETS triggering is enabled.

buffer_a, this is a pointer to the buffer to which data from A will go. It is
unused if the oscilloscope is collecting only from channel B. If the pointer is
NULL, nothing will be written here.
buffer_b, this is a pointer to the buffer to which data from B will go. It is
unused if the oscilloscope is collecting only from channel A. If the pointer is
NULL, nothing will be written here.

overflow, a bit pattern indicating whether an overflow has occurred on a
channel, bit 0 overflow on channel A, bit 1 is an overflow on channel B, bit 2 is
an overflow on channel C and bit 3 is an overflow on channel D. Where bit0 is
the LSB.
no_of_values. The number of data points to return. In streaming mode, this is
the maximum no of values to return.
The actual number of data values per channel returned which may be less than
