Brand new devkit - knob failure?
by dhodgson on 2011-08-26 17:31:34

Well,

My ToneCore devkit just came in - actually, it's my second because the first one Line6 sent was DOA. The second one works, but before writing a single line of code I can't help but notice that three of the knobs in the TCDDK_GUI.exe application don't update correctly. When turning knobs on the ToneDock module, three of its rotary knobs (and all switches) update smoothly in the GUI when turning them, but two don't turn at all (they seem to vibrate slightly as if from some kind of trimpot noise) and one of the three knobs rotates fine but also makes two others rotate in sympathy along with it!

This is where I have to wonder - did I just get another bad pedal from Line 6, or might this be something that could be solved my reflashing the MCU?

I can't recall anything like that, although that's based on a rather small sample size of one ToneCore dock and two modules. The knobs don't have a perfectly smooth sweep, but they've always worked well for me. If you mess up your code badly enough to freeze or such, you can cause the whole thing to become unresponsive, but even then, they're either all working or all not working.

If you have access to a regular ToneCore pedal (such as Verbzilla, Echo Park, etc), you might try one of those commercial modules in your dock, to narrow down whether the problem is in the dock or the module. You might also try the other case of the dev module in a regular dock. Also, have you tried just twiddling the knobs while hooked up to an amp, to eliminate the possibility that the knobs do in fact work, but perhaps the USB communication with the TCDDK GUI is failing somehow?

I doubt reflashing the module will help, but it can't hurt, and might give you more information. Sorry I can't be of more help, but your issue is definitely not normal - you might want to get in touch with Line 6 support directly by phone.

Good luck!

Hi Dallas... I came across your thread and my first impulse would be to suggest relashing the MCU, yes. Also, have you tried other USB ports on your host computer?

 

However, since none of us Forum Moderators are firmware programmers we don't have the scope of knowledge to really provide you concrete answers when it comes to DSP programming questions with this very specialized product that was offered a few years back.

 

I've contacted software engineering internally for some advice/suggestions on your issue. In the meantime, please reflash the MCU if you haven't do so already... worse case scenario we may need to get another module to you.

Interestingly I've had the exact same problem; two knobs unresponsive and slighty vibrating, one turning the other in sympathy, despite relfashes of the MCU. A second module has been working fine however.
