Re: Taking a current Line 6 effect, and putting it on a single Dev Kit Pedal. Possible?

support@line6.com — Thu, 15 Mar 2012 04:15:48 GMT

Short answer is no, it's not possible.

Long answer is sure, Line6 could probably implement a lot of their effects on this hardware. But you can't just copy an effect and drop it on the dev kit pedal. The purpose of the dev kit is to write your own effect. Perhaps you could implement a similar effect on your own but I don't think that's your skill set.

Sounds busted.

Re: How do I get my ToneCore Development Kit working on Windows 7?

Another option is to simply use a virtual machine to host a 32-bit Windows installation and do your development (or at least your flashing) from that VM. I've used VirtualBox successfully running XP hosted on Linux. I suspect a Windows host will work as well.

The cable you connected is a mono cable, yes? A stereo cable won't bridge the power for the device.

Green light come on on the pedal when you step on it all the way?

Re: TCDDK on 64-bit OS?

My guide has some notes on setting up VirtualBox and getting USB working:

http://audioartillery.com/projects/tonecore_dsp_dev_kit_guide?p=3#10

It's been quite reliable for me (XP hosted on Linux). One really nice thing about setting up a virtual machine is as you upgrade to newer OS's (Windows 7, etc) you don't really need to do anything to keep your development going. I think it's pretty clear that Line6 won't be updating this kit in the future.

Have you tried that XP compatibility mode that 7 supports? Might work...?

Virtual machine works great for me. To be honest I prefer it.

Re: new ToneCore Developers Kit pedal not working

Certainly doesn't sound right. May be worth trying a 9v just to rule out power supply connector problems etc.

USB enumeration shouldn't be tied to the pedal state at all. Must be some kind of mechanical flexing or loose conneection as you hypothesized. May be simplest just to get it replaced.

Yup... here's the mention of this in the FAQ:

Re: Pitch detection/octave effect

MC, yes, I was being bitten by the fixed point register behavior. And I even put an entry about that in the FAQ I wrote way back when! I'm not sure exactly how it's working at all, but I'm sure once I change it to use a general purpose register it will work perfect.

Panda, glad to see you chiming in after so long. That's a good way to handle loading. Probably better than what I'm doing - looking into P memory every time I do a lookup. Though if you do this you blow both your P memory and X/Y memory.

Aight... hopefully next time I post I'll have a working sine wave and it will sound bitchin' .

You're right, it's MOVEM not MOVEC. I was confused. I'm honestly not very good at th 563xx assembly, I'm only really familiar with ARM processors.

I got it working but I'm a little confused. Here is what I'm doing:

move #SINE_LOOKUP_001,x0 ; this is the 2nd index in my table
move x0,a
sub #$6,a ; <--------- account for address being off by 6
move a,r0
movem p:(r0),r1
move r1,x0
move x0,x:Debug_Read_from_DSP_3 ; <--------- I see the 2nd element in the table

As my comments indicate, my MOVEM instruction seems to be fetching from the address 6 words ahead of where I want it to. Any idea what I'm doing wrong?

As far as the MCU initialization of X/Y mem, I think the simplest thing to do is to use the shared memory interface that is currently used to pass knob values and come up with some protocol that is used at boot time to transfer your gobs of data. But with the linear interpolation I think my table will end up being quite small so this is a non-issue.
