New Rigol HDO1000 12-bit DSO - BUGs

--- Quote from: hfiennes on September 08, 2023, 09:56:39 pm ---Basically, the scope is always assuming 10 bit addressing. There is nowhere to set 10 bit (I guess the "without/with" sets 7/8 bit) so I can't clear it. I've tried setting 7 bit addressing in the I2C trigger and copying this across with the "copy trig" button in the decoder setup, but no luck.

It came with 2.00 and have updated to 2.11, but the bug persists. Anyone else see this? I was going to try a factory reset in case there's something randomly stale, but couldn't find one of those either.

I counted the clock pulses between the first start and stop in that image and there were 18 of them. Is the 'scope wrong in assuming 10 address and 8 data?

First mention that the Fw. 2.11 is out. I missed that.
From release notes:
00.02.11 2023/08/17
- PassFail function optimization
- Ref function optimization
- Read screen data, fix the abnormal number of return values
- Waveform distortion before triggering with large time base
- CAN trigger related issues resolved
- Fixed the wrong format of saved memory bin wave file
- Fix low storage depth, after ZOOM is turned on, the square wave will be stabbed
- Fix the data abnormality at the end of the high-resolution mode waveform
- Fixed the inconsistent behavior of XY window switch operation
- Fix the invalid initialization of webcontrol network settings
- Fix Pass/fail cannot be terminated
- Fixed the problem that SCPI could not get the measurement value
- Fixed the problem of loss of test mask in special cases
Anyone is still encounter trivial bugs like scope crashing or Android stop messages (like in Dave's tests with DHO 800)?
From 2.07 version I did not encounetr this kind of problems but maybe I'm not using the scope enough.

[...]
It feels like the light isn't passing through some of the holes in the encoder wheel as the issue is present at the exact same spot on the dial. I've not taken mine apart, just guessing based on what I know about how MCUs process the signals from a rotary encoder (example attached).

FYI, practically all rotary encoders used as human-machine interface (HMI) elements are electromechanical, basically a type of rotary switch, using flat contacts on one half and slightly offset leaf spring contacts on the other half. (Which contact type is on which part -- the rotor and the base -- varies by model.) Optical rotary encoders are very expensive and are used only on high-reliability HMIs like aircraft cockpits, and as the absolute-position encoders on rotary shafts in things like robotics.
The only optical rotary encoders found commonly in consumer devices are the ones used on mouse scroll wheels. (And long ago, when mice had balls, as the ball encoders, too.) I suspect it's simply because the wheel needs to be clickable, and the simple slot-type photointerrupter allows the use of a slotted wheel that can move up and down a bit.

I recently received my Rigol DHO1072 from Aliexpress. Wow, big & beautiful. Almost the first time I turned it on and I found a bug, recipe:
- enable 10x probes on both channels (note, without 10x it is not repeated)
- trigger rs232 115.2k
- decoder channel 1 rs232 115.2k bus status on
- turn multipurpose button 1 until full screen "RIGOL.SCOPE has stopped"
ps many thanks to this forum, opened my rigol up to DHO1202 :-+

Update your firmware and try it again. :)
