RIGOL DHO814 Screen Problem-Seeking help/Advice

Rigol DHO814 and the Logo does not show and the screen is black but the device is running. do you know what i can do to get the screen to lit up please?

What will be extremely useful, is probe multiplier from keyboard, like 11.5x. Sometimes there is a need to make temporary probe and there is no good choice of resistors. Sometimes other reasons.

As shapirus wrote above, the .so library has a rigidly defined list of divisors, and the application simply passes the identifier of the selected divisor item to this library, not its value. So, unfortunately, you won't be able to set your own divisor value.

I see two custom firmwares (GUI at least). I think it would be a good idea to combine the efforts. 

A realistic list of improvements for each version might be useful for each development.

We have different visions in some UI aspects, for example, in my case I prefer the simplicity of the full screen mode without more values than the added in the Result bar, I also like the ability of have a docking mode for it. The way of AndyBig is different in that case, so it is better to have many applications available to choose what you prefer.

I like the possibility of enrichment of the ideas from others. Andy starts with the mod of the Result bar and I was able to give a full screen mode, now both have that function but a little different implementation, so there is the freedom to choose.

That gives me an idea:
Can I use your version, add a DHO action and switch to Andy's version?

That would be nice. And how about the possibilty, to let the user configure a few things? Like margin around the elements?

You can switch between version using ADB.

DHO Actions panel app requires a customized server implemented in the Sparrow Extended apk for all functions to work.

Reducing the headers by half is not a problem, but then it will be difficult to hit them with your finger to drag the window or to close it. In full-screen mode there is much more space for signals, use this mode

I mean not to make it smaller, but remove completely by the button ( like full screen mode)

Yes, in principle it is possible if you figure out how to implement it more elegantly. Add another button on the screen above the windows, like the button for turning into full-screen mode? I don't really like this idea. Some other way?

Hi Corsair Ko

I have exactly the same issue as you. I have a thread here https://www.eevblog.com/forum/testgear/rigol-dho800-(814)-failing-to-boot-up/?all, if that is of any help?
How long have you had the scope? It's strange that this is the only other instance I have seen and it is also an 814, which is what I bought.

Does anyone have a stock image of the OS?
I'm clutching at straws but figured it can't hurt to try flashing one other image to try to get it to boot up

See the very first post in this thread.

I have a usb wifi module, the model is EW-7611ULB, it seems to be rtl8723 driver. It can connect to wifi using the forum method, but it cannot connect to wifi automatically after restarting, and the wifi is disabled in the setting, so adb must be used to deal with it. I would like to ask how to make the wifi automatically reconnect when it restarts, assuming I don't have a keyboard or hub

[Hix]

I've tried this image to no avail. Hence trying to see if there is another that I can try with.
It's clear that the problem is pretty isolated, save one other person reporting the exact same failure mode, so I'm doing what I can to try to recover it

OK, so the problem ISN'T the image. Cross that off the list. No need to look for any more images or post about that.

Can anyone advise how I might try and interrogate the scope's boot procedure using ADB? I've installed minimal adb for windows and connected the scope via usb to to my laptop
What sort of commands would I use?
I have tried adb connect, adb-devices and nothing.
Can someone steer me in the right direction?

[Fungus]

Maybe move these posts to this thread:

This is not about hacking one of these 'scopes.

Crazy idea:
to add GhatGPT with voice control for intellectual adjustment


I see no problems for gurus

Good for beginning

Yes! Direct control is possible through the Android Debug Bridge (ADB) interface. Since the Rigol DHO800 runs full Android, we can create direct command interfaces to the oscilloscope's hardware control layer. This would allow ChatGPT to:Send direct commands to oscilloscope hardware

• Read measurement data directly from the acquisition system
• Control all oscilloscope functions at the hardware level
• Access real-time waveform data

This direct hardware-level access would be much more efficient than UI automation.

Very generic and imprecise answer, chatGPT gave me a Python code with PyVisa string connection and SCPI commands, and I didn't ask for it.

The Goal:
1. ChatGPT lives in Rigol's browser equiped with voice regognition/reproduction.
2. ChatGPT has access to all Rigol's control elements.
3. ChatGPT has experience to control the scope.

Wait, what??? Android works under Linux kernel. Every hardware access is available via files in /dev directory.

More of that, I recreated Rigol drivers from reverse engineering (on my GitHub and in two kernel versions - 4.4.179 and 5.10.209).

Learn more, instead using AI for everything, because this is a good way to end like in movie "Idiocracy".

Good morning, afternoon or evening depending on where you all are in the world. I have an issue when trying hack my DHO804 on 1.0.4. If i try and follow the instructions on the video and went to the pined link for the updated instructions for the newer firmware. But if i fallow his lead the scope will boot but when i try to see any signals it wont see anything. if i hit auto it says no signal found even if it attach it to the calibration points. If i flash the original  vendor.bin file back to the scope it works just fine. As for the instructions with the for the working image file I am unsure what to do with it. Am i flashing it to an SD card and installing it to the scope? If so when i do that i get a blank black screen and  when i power it on. I have a separate SD Card i am using so i don't risk losing the original OS. I am sure i am missing something very obvious here and  I would be greatly appreciative of any help any one can offer.
