Troubleshooting power issues?

Dpalm010

Hi,

My lab purchased some pre-assembled pulse pals within the last couple years. The other day I noticed one was turning on and off by itself (not the triggers or inputs, but the screen/unit itself). I figured that it may have been an issue with the micro-USB connection since it seemed to do so with movement. I tried cleaning the micro-USB port with compressed air and now I can't seem to get it to boot at all. I've tried different cables and different power sources. I think we have another unit with a similar issue so it would be great to get to the bottom of this.

Since I didn't build these and have only very recently started using them, I'm pretty unfamiliar with their design and troubleshooting. I've been reading the wiki and some posts on here but I'm wondering if anyone has some tips for fixing and/or troubleshooting this.

I am under the impression that the issue could be not the micro-USB port or power, but the screen itself. If this is the case I think I should still be able to detect and control the device with Arduino IDE & Pulse PalMatLab code. I couldn't seem to get either of these to work on one PC despite the device seemingly being identified as "COM1" in device manager. This specific PC is behind on some Windows updates that I think may be interfering with the Pulse Pal drivers so I may just need to try on another/updated PC.

Thanks for any advice!

Hello DPalm,

Windows doesn't usually assign USB serial ports below COM3, so if there's nothing else in the Device Manager you probably have a dead Arduino Due board.
Since you purchased these from us, please reach out to sales@sanworks.io. We can swap out the Arduino board for you, or assist remotely if you'd prefer to do it yourself. For reference, the firmware we'll upload to the Arduino board is here, and upload instructions are here.

Thanks,
-Josh
