Just a wild guess: you are probably facing some undersampling here - the encoder outputs more signals than the PIC input / the shift register can handle. You are using high resolution encoders, right? How many peaks per turn do they output? (I got this idea because the problem looks similar to what can be observed in those western / cowboy films: although you know that the coach is moving forward, sometimes the wheels seem to be turning backwards - that's because the "continuous" movie is actually a 24 pictures per second, and undersampling occurs.) You should probably try to connect the encoder directly to some input pins, e.g. on Port A ? Best regards, ilmenator

They arrived safely in Norway today. THANKS!

That's a very clever idea!

Yes, one of each would be fine! Hehe, that's good thinking! If you have a use for those power supplies then keep them intact, otherwise send me the leads, too - I have two universal power supplies, but the connector hole is a little too wide so the contact is only made when I tilt the connector a little (I use a rubber band to do this, but it's kind of fragile). PM me how much you get for this. THANKS! ilmenator

Hi Prof, I did the complete UK classic factory reset, see here. Now it's working again! I noticed that I can't use the power supplies because the wall plug part cannot really be modified, and of course they are the UK model. If you kept them, the rest is a little over 215g I think (Cybiko and serial cable). If that reduced shipping costs, I'd take another pair. Oh, and are there other colors than neon yellow in your collection? :) Thanks a lot, ilmenator

The ableton MIDI documentation should tell you what messages ableton expects. (Alternatively, you could sniff the messages sent by your UC33e controller, e.g. using MIDIOX). Assigning MIDI messages to certain buttons on the MIDIbox is a piece of cake, see the various C code examples, e.g. here. Or, you take a look at the MIDIbox LC.

...and a gear shift for different fader sensitivities ;D

Of course it is! So, let's see how it looks like, what features it has (duo-LED button matrix?), etc! Best regards, ilmenator

Probably not, but you could use one of those Spectrasymbol soft pots / membrane strips. Sparkfun has them in 200mm and 500mm length. Of course, that's not the same as nice, smoothly running mechanical fader :). Best regards, ilmenator

I use Target: http://server.ibfriedrich.com/wiki/ibfwikien/index.php?title=Main_Page Best regards, ilmenator

Hehe, I've been thinking about a "driver" for my SRAM implementation as well, but the concept of "driver" is still a bit over my head. I tried to look into the J5_IO module implementation, but as I am not a programmer the formalisms involved seemed too complicated to me. Also, I'd be interested why you chose the 4066 (as they are "4-bit" only)? But I guess we are hijacking this thread already...

Would you tell us more?

They arrived in Norway yesterday - thanks a lot! After an extended Pinball session, one of them gave up already - after the reset, I got a message that the Flash was going to be restored, but now it just hangs after the OS version screen. I guess I'll have to look at those Wiki pages ;D. Best regards, ilmenator

Great, thanks! [edit: I had a typo in my code that gave a nice little error... hence a bit of confusion with some discussion in the chat :)]

I am using J5 as digital output for a number of control signals. As these signals might be located on other pins in the future (depending on the hardware design), I would like to design my code such that the "pin mapping" can easily be reconfigured in the future. So, instead of writing PORTAbits.RA2 = 1; I would prefer something like with Clk_LData being the name of the signal. I'm still no programmer, but would something like ///////////////////////////////////////////////////////////////////////////// // Global definitions ///////////////////////////////////////////////////////////////////////////// #define Clk_LData PortAbits.RA1 in main.h do what I want? It compiles okay, but I am without hardware right now and cannot properly test it... Thanks a lot, ilmenator

Some sneeze you have. I bet it's only because you don't blow your nose ;D.

Plus: it rather looks like a dead horse, see this thread. No development in the last 1.5 years, and the name not really convinced that it's worth the effort... Best regards, ilmenator

Yes, the screen is 2D, so you are reducing the number of degrees of freedom!

In a university project we used the Space Navigator as an input device for moving through a virtual world (instead of using the mouse or computer keyboard). The many degrees of freedom that the Space Navigator offers can actually make your life there more difficult, because you end up tilting and rotating if you do not have sufficient training to develop your minute motor activity the way the Space Navigator demands it. Seen this way, the Space Navigator is just like any other musical instrument that needs a certain amount of training to be mastered. Best regards, ilmenator

Hehe, I can't read the display - it's too small in the small version and too large to fit on my screen when expanded (plus, I hate scrolling sideways because that means I need to adjust the vertical scrollbar up and down, back and forth). Couldn't you just downsize that picture to something like 600x480 pixels? Also saves bandwidth... ::) Best regards, ilmenator

It's a great device, also works in Google Earth and other apps. What about the original idea of connecting it to a PIC? Can those PICs with a USB interface act as a USB host? Best regards, ilmenator

That sounds GREAT! THANKS! Best regards, ilmenator

Another recommendation is Target. The only limitation of the free version is that you cannot make drawings or PCBs with more than 250 pins/pads. In the German computer magazine c't there once was a version that has the limit raised to 400 pins/pads. That's what I am using since two months or so, and so far it's great! Best regards, ilmenator

Although Helge's (that's the guy in TK's video) style might be a little strange, he is actually a very good jazz musician. I saw him live, and his playing was great! Best regards, ilmenator

2 for me, too - please!
