Shakeit Motors problems since 9.1.13

[RipperGOT]

Describe the bug Since update 9.1.13, it disconnects after 5 or 10 minutes on the Arduino Uno board. I have tested all the updates, and it only works properly with version 9.1.12. I have also tried the Fake Chip drivers, etc. I have tried different Arduinos, and it still happens. The only way to prevent the board from disconnecting is to downgrade to version 9.1.12.

Simhub version 9.1.1X

Third party plugins None

To Reproduce Steps to reproduce the behavior:

1. Connect Shakeit Motors
2. Play for a while
3. The board disconnects
4. Remove the USB cable and plug it back in
5. The board works again.

Hi !

This error is an hardware error, it's not software, it means that the usb chip is failing. The only change about shakeit since 9.1.12 is about some effects content scale, they scale differently and can be more contrasted. https://github.com/SHWotever/SimHub/releases/tag/9.1.13 and might leverage some wiring/board weaknesses

If you have such failures I would recommend to check the power source as well as the wiring. And eventually lower the output gain as a quick workaround.

Could you also join the full log files as requested in the template?

[SHWotever]

Nb : the fact that you have to unplug and plug back the board proves that the usb chip has failed as the log is showing. In case of basic software issue simhub would simply reconnect after a few seconds automatically. But since the chip has failed it's impossible to do it on your case.

I think it's a software issue. 3 'bad' boards? I ran a test by resetting the PC while independently powering the Arduino board (to prevent it from resetting), and it worked. It's like the USB port is freezing. It only happens with versions later than 9.1.12. With that version, it never disconnects.

[SHWotever]

Hi ! It's indeed the usb to ttl chip which is freezing/crashing. But this chip only acts as a "bridge" between the Arduino chip and the computer. It's not programmed or controlled by the software.

My opinion is that the "reinforced" effects are stressing a little more the Arduino/power source. There have been absolutely no changes about how simhub communicates with the Arduino with this version and later one, that's why I'm completely confident it's not software. (And the errors also shows it : " a device attached to the system is not functioning" is an hardware error pretty common when the hardware is "giving up")

Have you tried to lower the gain as recommended to check that ?

[RipperGOT]

Yes, I have also tried lowering the gain, and the same issue persists with all three Arduino boards. The only thing that prevents the disruptions is downgrading to version 9.1.12.

[SHWotever]

Hi ! Thats really strange I double checked all the changes since 9.1.12 (which was quite long as there were more than 600 files to review :D ) but I've not found a single change about the arduino. Only effect responsiveness and scaling.

To quickly orient the research : could you try to simply unplug the motors from the board and run it as usual. It's an easy test and it will allow to quickly see if it's an hardware issue. If the board still disconnect, that would mean that indeed the code is somehow at fault.

If it still disconnect, I would need to have a better overview to orient my investigations, could you join ;

• The the full log file when it crashes as I asked you so I can see better the context ?
• I would also need as well a complete description of your setup (arduino board, shield model, power source characteristics (voltage, amps ...) as well as the power wiring (ideally completed by a picture),
• Your full shakeit settings file (stored in C:\Program Files (x86)\SimHub\PluginsData\Common\ShakeITMotorsSettings.json

Ok mate! As soon as I have all the information, I will upload it.
