Programming

5.3.1
C
There are two C example programs: one is a simple GUI application, and the other is a more
comprehensive console mode program that demonstrates all of the facilities of the driver.
The GUI example program is a generic Windows application - ie it does not use Borland AppExpert
or Microsoft AppWizard. To compile the program, create a new project for an Application containing
the following files:
ps3000.c
ps3000.rc
ps3000bc.lib

streaming mode. This function is essential for ETS operation.
handle, the handle to the required device.
times, this is a pointer to the buffer for the times. Each time is the interval
between the trigger event and the corresponding sample. Times before the
trigger event are negative, and times after the trigger event are positive.
buffer_a, this is a pointer to the buffer to put data from channel A into. 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 put data from channel B into, It is
unused if the oscilloscope is collecting only from channel A. If the pointer is
NULL, nothing will be written here.
buffer_c, for future use -set to NULL.
buffer_d, for future use -set to NULL.
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
