struct.error: 'I' format requires 0 <= number <= 4294967295

Hi Mikhail,

Thanks for creating the script. I have tested it with a Keysight Oscilloscope and it works perfect. I have a loop in my code that sweeps and collects data from the scope, but Im getting the error message shown below "_create_hislip_message
message_dict['message_parameter'] = struct.pack('>I', message_parameter)
struct.error: 'I' format requires 0 <= number <= 4294967295". I get the error after 8 successful loops.

Regards,
Tony

Just passed by - late to the party.

But in case someone else may be interested in a solution to this issue, it would just require changing the format string >I (unsigned int) to >Q (unsigned long long), as described in the documentation for struct

Example:

message_dict['message_parameter'] = struct.pack('>Q', message_parameter)

Occurrences to change:

PyHiSLIP/pyhislip.py

Line 198 in 52a8422

message_dict['message_parameter'] = struct.pack('>I', message_parameter)

PyHiSLIP/pyhislip.py

Line 381 in 52a8422

message_parameter = struct.unpack('>I', raw_message_parameter)[0]
