Cannot obtain HP8753 descriptor #10

Closed tomverbeure closed 7 months ago

tomverbeure commented 7 months ago

Hi Michael,

I'm able to compile the binary just fine, but when I start it, I get the following:

tom@zen:~$ hp8753 
libgpib: invalid descriptor
libgpib: invalid descriptor
libgpib: invalid descriptor
libgpib: invalid descriptor

The GUI also says "Cannot find HP8753".

When I use ibtest, things are working fine: I can open the device (address 16), I can write "IDN?" and read the HP8753C string:

om@zen:~$ ibtest
Do you wish to open a (d)evice or an interface (b)oard?

I tried running with the -d 7 option, but that doesn't seem to be logging anything?

I'm attaching an strace file in case that helps.

VK2BEA commented 7 months ago

Look at the journal to see the error and debug logging. Something like .. $ journalctl -t hp8753 --since '5 minutes ago' You should see (when successfully receiving a trace) a log like that below. What GPIB interface are you using?

tomverbeure commented 7 months ago

Ok. Problem solved. This issue is that I didn't know of the existence of the GPIB menu.

It didn't occur to me that there'd be additional menu options left and right of the "Calibration Trace Data" options:

Screenshot from 2024-04-07 16-19-41

I'm not sure if the software is supposed to discover the GPIB device automatically or if one is always supposed to manual set the address?

Maybe the GPIB menu should be a bit easier to discover?

tomverbeure commented 7 months ago

BTW: the rendering of the imported data is beautiful! :-)

I think you can close this issue. A short term 'fix' might be to just mention in the README.md that you can manually set the GPIB parameters with the GPIB menu.

VK2BEA commented 7 months ago

yes .. interface design choices 8) Given your experience, I'll see if I can have that menu selected when the program first starts (i.e. when there is no database found). As far as the annoying splash screen goes, I'll disable that when the --debug switch is used.

VK2BEA commented 7 months ago

OK, I made those two changes ... if you start with --debug 2 (or greater), the splash screen won't show. On first run (when .local/share/hp8753c/hp8753c.db is not found), the GPIB tab is pre-selected.
