Hacking the Rigol DHO800/900 Scope

[AndyBig]

i install a008 just now,but my device still show （a007）00.01.01.sp1 

Damn, I forgot to change the version ID

How does the “Settings” button appear under the Start menu?

That is implemented here:

Thank you very much, but i can't open youtube videos in my area :'( :'( :'(

What settings do you mean? Oscilloscope settings? Or Android settings?

[Trun_T]

it‘s  ’“Android setting”

[Trun_T]

Your software "Sparrow_mod" can add this function, that is, in addition to adding "DHO800" when the screenshot, add the date and time, like this

I'll have to check, but most likely the screenshots are taken in the binary library, meaning the app mod can't affect this.

Tried to connect DHO804 via WiFi. May someone use wireless connection and can tell should it be so bad?
With such lags Webcontol become almost unusable. ((
LAN connection works flawlessly.
Attaching a ping window screenshot.

Tested using ping command from Windows command prompt:

ping -t xxx.xxx.xxx.xxx
where xxx.xxx.xxx.xxx - scope IP address

I have this on WiFi. On a wired connection, a stable 1 ms.

This is a proof of concept of an editable button panel, the configuration file will be a simple text file in JSON format stored in the user storage space, the panel can have many buttons, it is scrollable and currently supports chained SCPI commands and launching applications.

A new version is coming! With powerful features!

Thank you so much for your test!
Much better than main. Should look for a better WiFi adapter instead of cheap Chinese crap.

It is ready now!! and it is free for all subscribers of the Enhanced Plan in Patreon. It is also free for all who have already purchased the version compatible with firmware 00.01.04. I will write some instructions on how to use and configure the DHO Action Panel. Have fun with it!



In the example, load settings and save settings refer to the device settings, so you can quickly save a configuration and later recall it like a custom default button. Of course, you can create multiple Load settings button linked to STP files in the device. The glyph, caption, and action of each button are user-configurable, but this is not a easy task because I tried to keep the panel light. You can use any browser that can access the normal storage in Android and edit the dhoactions.json file. The result bar/Measurements can be docked/undocked using the popup menu of the items in the bar.

Thank you @AndyBig for your improvement!  The scope becoming looks like instrument!
Just installed latest version to try. My scope is 924 was loaded with 1.0.4
Some difference noted during install:
Cache file in dalvik-cache not exists.
It's failed to re-mount system partition as read-only after installing services.jar
Sinked it several time and rebooted without issue
After uninstalling sparrow.apk scope closed it and started again in 1min as 1.0.0.1
Hacked APK installed on top of it - no issue.
I'm very appreciated new look, still plaing with it.
Some optimization is seems to tight for me - measurements font in compact view is too small - in details view it's ok and readable.
Could you please make it the same size as details or higher. DVM  looks the best, but it will not enough space for label in 1 row.

Ideally, selectable font size
Unfortunately, horizontally splitted windows sill waisting to much on window headers. Is it possible to hide window header? Similar to status bar.
In multi-window mode vertical axis scale become too tight, not readable. Is it possible to hide half of it?

Hi guys i have a question. How can i clone the sd card from dho800?I like to have one buck up for safety.I run google search and i can"t found the right page on the eev forum.Thanks for any help.

Yes, a couple of people reported this as well. I still don't understand why some oscilloscopes don't have this file.

It's failed to re-mount system partition as read-only after installing services.jar

In principle, it's not critical, after rebooting the partition will still be mounted as read-only.

Yeah, I've thought about that myself. Maybe I'll switch between large and small views. It'll be easier to read with a larger font, but fewer items will fit on the screen.

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

It's literally the first post in this thread.

I was curios about the actual wasted space on those borders, so i started counting pixels  . I counted 39 pixels (vertical pinks lines), and then for comparision, i drew a rectangular with the same height. So by removing those borders, the waveform view could be made significantly bigger, or two lines of information could be displayed on the whole width of the screen. Of course you could do a combination of those.

And there is of course space wasted in the horizontal way.

In the next release of the mod, owners of 802/812 models who have changed the model to 824 will be able to disable icons for missing channels Disabling icons for channels 1 and 2 is blocked. The settings are saved when the oscilloscope is turned off.

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.

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

Adding my own, will be three of them. Currently Im aboard at work and without this scope, so my development is paused.

I'll be happy to be proven wrong, but it seems like the multipliers are hard-defined in the .so library, and so implementing this may be unfeasible.

That doesn't make it impossible.

Anyway, I will be happy to have more time for development, because I already started app under Orange-Rigol and I needed to change way to start this app, which is almost done. Right now Im aboard for about 1-2 months. After making it work, it should be quite easy (but time consuming) to reverse-engineer whole app communication with AFE and FPGA, to make or port another working app.

That was my idea also, but their economic models are different.
