thanks for the information...
1) Disconnect and reconnect the scope both, USB and power..... Solution very Good
2) when I try run example block diagram.. labview crash...
problem..Exception: Access violation (0xC0000005) at EIP=0x0000000100000000
version: 14.0 (64-bit)
change the VI in example from 32 bit to 64 bit..
a)Ensure that you are using the 64-bit version of the dll (and wrapper dll for Oscilloscope Streaming) and that the dll is loaded in for each function call.---------(OK copy from SDK kit 64 bit file)
b)Unsigned 32-bit Integer for PICO STATUS values.------(OK data type change in parameter)
c)Signed 64-bit Integers for pointers to callback functions and void pointers ----( ?? not change )
