Hi guys,
Since I’m using my Zbox I’m experiencing the Select Option Encoder/Switch it’s not accurate very often. I mean, I rotate the encoder to select my choice but when pressing the switch the item selected moves up or down and then it is loaded.
Has anyone experienced this issue?
Regards.
Hi @smespresati,
I have sometimes the same problems but I thought that maybe a problem of my (cheap) china encoders.
Do you also use cheap encoders?
Regards, Holger
Hi @C0d3man,
I ordered a full kit containing all parts to build the ZBox to @jofemodo, so I cannot tell you where he got it from.
Regards.
He has the right ones (not as my china ware) for sure @smespresati.
@jofemodo sent me the specification of his encoders and compared to my ones they are very good.
Regards, Holger
Hi @C0d3man, here is the spec:
https://github.com/zynthian/zynthian-hw/blob/master/parts/RotaryEncoderBourn-PEC11R.pdf
Anyway, it’s not a hardware problem, but a software problem: Currently, the list selector changes the selected item every 4 encoder ticks. The encoder have 24 detents, with 4 ticks each detent. That’s OK and every detent changes the selected item. This is great when going down thru the menu: you need to move a complete detent (4 ticks) to jump to the next item. However, when going up this doesn’t work very fine. A slighty movement of only 1 tick will change the selection. This can happend very often when clicking the switch, and you get selected the wrong option.
But i’ve a solution in my mind. Let me try it and will see … 
Hi! I’ve implemented a kind of histeresis in list selectors, so it should work slighty better.
Please, from Zynthian Admin Menu:
And test if it works better …
I also noticed that the schematic on github not always represents the physical pinout of the used encoders. Mine common was in the middle (A-C-B), while others are A-B-C.
Perhaps take a look at the midibox software, where this also was a problem…
Current PCB design is for ACB or BCA encoders. Perhaps the schematic is not accurate 
You better ignore it and use the breadboard view or directly the PCB.
Anyway, with the software fix that i have implemented, it should be enough
Hi all,
Just updated my ZBox and now the enconder works much better. I guess the @jofemodo’s patch did the trick. Thanks.
Regards, Jose.
Hi @all!
I have implemented a new speed-sensitivity algorithm for the rotary encoders in the zyncoder library. After you update your zynthian software from the admin menu, you will note the difference in the controller screen. Now you can adjust step by step the parameters when you move the rotary slowly, but if you twist fast, the step will increase to 2 or 4 to allow sweeping the full range without changing your fingers.
Please, try it and give me feedback!
Looks like the interface (scrolling) is more responsive 
Can I update without having to alter the /boot/config.txt?
Hi @Keeze101!
You can protect your boot/config.txt against the update system by adding this line:
#NO_ZYNTHIAN_UPDATE
any place in the file.
Currently this trick only works with the boot/config.txt, but i would like to extend the trick (or something equivalent) to any configuration file affected by the auto-updating system.
Update your software. I’ve fixed some details …
Hi @jofemodo,
I’ve jus updated my ZBox and I think something it’s not working properly. I will describe. When one of saved presets is selected and loaded the Back switch stop working, which means the ZBox must be rebooted in order to change the engine/instrument.
Can you check it out, please?
Regards, Jose.
I do not have this issue… All seems to work fine.
Hi @smespresati!
Can you confirm the issue? The problem is still there?
@jofemodo
I have tested yesterday the update and had no problems.
Regards, Holger
Hi @jofemodo,
Yes, the problem is still here. Seeing the update worked fine for other users I assume something went wrong with my update. The problem is really weird because if I don’t use any of saved presets the Back switch works as it should.
The easy way to fix it I think is reimaging my SD. Perhaps @jofemodo can tell me a way to re-update without reimaging (I tried several times to do it using the admin menu without success).
In other hand, I’m thinking it’s worth it to reimage using the image @C0d3man has created with the promising MOD-UI. By the way, this new image can be updated, as usual, using the admin menu?.
Regards, Jose.
Hi @smespresati!
Please, can you give a “operation sequence” that reproduce the problem for you?
Can you login into your zynthian and run the zynthian’s software from the command line, as explained in the wiki?
http://wiki.zynthian.org/index.php/Zynthian_Network_Connection
In that way you can see the messages printed by Zynthian UI and perhaps you see something “interesting” …
Regarding the MOD-UI image from @C0d3man, it’s not a zynthian image … yet
This image is intended to test the MOD-HOST + MOD-UI software, a kind of “proof of concept”, but it’s not connected to the Zynthian UI (TouchScreen + Rotary Encoders) yet. Anyway, i think you will love to see the MOD-UI working, so please, give a try!!
Hi @jofemodo,
Here my findings about Back switch problem.
First, I’ll explain the issue details.
Inmediatly after boot the ZBox shows a list of presets on the screen. If I select and load any of them the back switch stop working. Nevertheless if I select NEW to create a preset or just press Back switch to go to the Engine Selection window the Back switch works as it should.
Because it was very simple to do it, I decided to “reimage” the SD card. Once done and before to perform the update, I tested the back switch which worked perfectly. Then, I updated the Zynthian Software and then the problem arose again. Below the messages logged in the ssh session (I tried to upload a txt file but it’s not possible)
I hope all my testings will help you to fix my issue.
