Setup Example

VB.NET

Dim Ret, Srlen, Cmd(31) As Integer

Dim Srbuf As String

Cmd(0) = 3  ' Number of talkers and listeners (in master mode)

Cmd(1) = 1  ' Talker address

Cmd(2) = 3  ' Listener address

Cmd(3) = 7  ' Listener address

Srbuf ="*IDN?"  ' Data of Send

Srlen = Len(Srbuf)  ' Length of Data

Ret = GpTalkEx(Cmd, Srlen, Srbuf)

C

C#

Python

Ret, Srlen, Cmd = ctypes.c_ulong(), ctypes.c_ulong(), (ctypes.c_ulong * 31)()

Srbuf = (ctypes.c_ubyte * 10)()

Cmd[0] = 3 # Number of talkers and listeners (in master mode)

Cmd[1] = 1 # Talker address

Cmd[2] = 3 # Listener address

Cmd[3] = 7 # Listener address

Srlen.value = len("*IDN?".encode('UTF-8')) # Length of Data

ctypes.memmove(Srbuf, "*IDN?".encode('UTF-8'), Srlen.value) # Data of Send

Ret.value = GpibPy.GpTalkEx(Cmd, ctypes.byref(Srlen), Srbuf)
