Re: [sigrok-devel] Status of HID-UART support for UNI-T UT612 in libsigrok

[Michael A R. <mik...@bt...>]

Everyone,

I have added a attrs line to /etc/udev/rules.d/60-libsigrok.rules, below 
the line for the UT612, of course not commented out.

I then reloaded the udev stuff.

I also created a 99-ut612.rules file in /etc/udev/rules.d, then reloaded 
the udev stuff again.

One thing I had in that 99 file was to create a symlink:


/dev/ut612

Which is a symlink to: I created that file to make sure permissions to 
/dev/hidraw0 were correct.

/dev/hidraw0

Which I now have.

But any attempt to get anything from the meter, such as:

sigrok-cli --driver uni-t-ut612:conn=hidraw0

Results in an error stating the port number could not be got from 
/dev/hidraw0.

With help from this list, and some help from copilot, I have made some 
progress, but copilot tells me it looks like the driver is not sending 
what it calls the 'poke' message when I specify the driver.

But today copilot has been particularly prone to telling me the wrong 
thing, and then giving me the right information when I challenge it and 
tell it it is talking rubbish.

And it keeps forgetting I can't see and asking me to look for the 
computer icon in the display.

So I think we can relax, AI is not going to take over the world, just yet.

I will work on this again tomorrow.
