Hi,

I thought that a short should be expressed as a smallInt in delphi, you coud try this:

function UsbAdc11SetDo (handle : smallInt, do_value : smallInt ) : smallint;
{$IFDEF WIN32} stdcall; external 'UsbAdc11.dll'{$ENDIF}

Best regards,

Hi,

When you change the number of readings to 50,000 you will also have to change the arrays as well....

ReDim values_a(50000) As Integer
ReDim values_b(50000) As Integer
ReDim values_c(50000) As Integer
ReDim values_d(5000) As Integer
ReDim times(50000) As Long

Hi, I am sorry to hear that you are having difficulties. It is not necessarly the speed at which you want to stream but the amount of data you wish to collect when streaming at 10KSamples per second to 100KSamples per second.

Hi,

Thank you for your enquiry.

It currently takes 700ms for the device to reset itself when streaming has been stopped. We will look into this and see if the time can be reduce.

Unfortunately, I am unable to give you a time scale when this would be available.
