Redesign the harware part to suit my needs (and yours comments are welcome!) using the modules already available plus special ones if needed (I think about something special…but we’ll see that later)
Port the actual firmware to MIOS and PIC18F452
Enhance the resulting application to handle the new features found in the hardware.
As it is my first midibox, I need to build a test & developement platform. I began by redesigning the JDM board today (hum yesterday :o ) and going on with the rest of the minimal harware : Core, DIN and DOUT modules because I hate those nasty wires under the boards
Here’s where you can find my current and upcoming work :
about the redesign of the jdm, maybe it can a good idea to add a voltage multiplier and a lm317 to get the 13.8V? This way the jdm module can be powered by an external 9V psu, or maybe with a 5V serial port?
Actually the board I’ve designed handles an external PSU using the method shown in the ucapps.de JDM page (on the bottom in section “troubleshooting”). A regulator isn’t needed as the zener diodes are limiting the voltage correctly : 5.1+8.7=13.8V (I assume so )
I’ve also included the pull-down resistor needed to flash PIC18F4X2 models.
I’ve not built my board yet but I’ll post some feedback about this method.
Since I am a total newbie to this forum I beg for acceptance of any misfortunate exclaims that I may be responsible of.
As a wannabe guitarist I propose that you have at least a volumepedal and/or expressionpedal to be able to use this for instance with a POD or V-AMP.
If there are any possibilities for it could the display be used to get the information that is visible on the POD or equal device? ( As I was thinking of starting my career in this field with a project like this I would rather see that it is kept simple, but it would be a nice feature if possible.)
I effectively think about including a volume/expression control pedal but this won’t be done before a long time because I prefer to concentrate on a simple design to begin and then implement those cool features.
I’ll keep it in mind for future improvements
…wait and see
About the displaying infos from the POD, I think it’s impossible because (afaik) it doesn’t send its state through midi. So there’s no easy way to know what to display :-/
Maybe I am misunderstanding something, but I think what you want is already easily done with MidiBox64. The only thing you need to do is substitute foot switches for the buttons. You can use the AIN module to incorparate a Volume/Expression pedal. Any customisation would only have to be done in the midi messages sent by the buttons(footswitches).
You’re right goyousalukis, the midibox64 is a better point to start than porting the actual floorboard. I’ll work in that direction … but I’ll need some specific improvements
I think that the MIOS C Wrapper is the better point to start for a floorboard project. It has the main advantage that it’s much easier for people to customize the source code for their needs.
First i’d like to thank you for your GREAT work!!!
Man, you rule
I’d like to try writing some code using C but I’m still learning the basics of this language :
I pretty much confident with ASM since I’ve already coded some stuff in ASM on a 68HC11, I assume the gap between 68xx ASM and PIC ASM isn’t that big, right?
I’ll try both because writing some code in C seems a good challenge to me 8)
Anyway, I’m waiting for some missing parts from my local dealer (inluding the PIC >:( ) but I’ll begin the developpement testings as soon as it arrives
I’ts funny to hear about this ‘not so known’ product and brand because it’s the one that made me think ‘hey what about building a floorboard on my own? It might not be so difficult!’
I first heard about this product from John Petrucci’s mouth in the Dream Theater Live at budokan DVD bonus when he’s talking about his setup :o
So a night, searching the web for good stuff to start the project, I found the ucapps.de site … you know what’s happening next
I don’t want to carbon copy their design nor the way their box works but we can share some code and design if you want.
I want far more buttons, displays and gear :
It’s all designed in my head … i’ll write this down later (I also have to sleep and work)
Glad to see that there are still some guitarists outside in that DJs jungle! (Don’t misunderstand me I like DJ works but I’m a musician … )
I’ve been really busy lately so the project staled for the moment. I have almost all the parts to build a developement system for this but no time actually. I hope to beggin building it on late January.
