Re: sigrok/pulseview support for DSO112A

I'm not much of a pulseview user' I tend to use the sigrok-cli command, and just run captures to analyze later. So I don't have one handy. And it really won't show anything about the DSO112A except saying "JYETech DOS112A" in the "Device" field. I'll see what I can do, though.

Firmware 08501-133?

I got mine, and got it put together, only to discover that it's running 08501-133, which isn't listed in the firmware for this device. I also notice that the ATMega48 was running 08502-50, and yes, I'm seeing some issues at higher frequencies. I was going to upgrade the ATMega48, but figure that wit...

Re: Part numbers for pushbuttons

Seems like the power switch is either out of stock or only available as part of a minimum order that's more than I paid for the kit. Can you recommend an alternative for it?

sigrok/pulseview support for DSO112A

I've finished - at least until the firmware issues get dealt with, see the thread on serial interface docs at http://jyetech.com/forum/viewtopic.php?f=17&t=844 for adding a driver for the DSO112A to libsigrok. I'm posting the source for the sigrok project folks to review while I wait on those fi...

Re: DSO112A serial interface docs?

I worked out the appropriate scale & offset values for V/Div = 1V, just so I could get data into it to work with while workingg on other things. I now have more questions/requests. In particular, I'm having issues with reliability switching into and out of USB Scope mode. It would be nice if I c...

Re: DSO112A serial interface docs?

BTW, if you're doing to be tweaking the firmware for this, any chance you could add a firmware version to the Configuration information? I'd like to be able to let users know that it won't work rather than just have things fail!

Re: DSO112A serial interface docs?

Well, I have noticed that VPOS changes as I move the cursor, so I assumed it was set and I just needed to know how to interpret it.

Just to be clear, the information I need ins't currently available, and I need to wait for a firmware update for that to appear?

Thanks.

Re: DSO112A serial interface docs?

Ok, now I need to figure out what the byte-long values showing up in the captured data output. The only description of how to compute voltages is in the section "Output of measurements". It's not clear it applies, as it says "All voltages are expressed in 16-bit signed integer.",...

Re: DSO112A serial interface docs?

Got distracted last week, but got back to this. I'm working on adding support to sigrok (an open source dmm/osc/logic analizer/etc. toolset) for the DSO112. I can read & parse the query result, configuration information and parameters. I think I've got a handle on that. But... I'm seeing packets...
