Hi there, Thanks to the forum I can successfully compile C applications using Xcode on OSX (well, the skeleton code, at least). But now I want to edit the lcd_interconnection_test_v1a code to customise it a little to my tiny LCD. As far as I see lcd_interconnection_test_v1a is written just in asm - at least there's only a main.asm, no main.c. So I was wondering what is the latest status on compiling assembly code on OSX (ideally via Xcode IDE)? Can it be done? The wiki talks a lot about C-applications, but when I tried following the same example for skeleton_v1_9a then I can never get it to work. Same environment and script files as the successful sdcc_skeleton_v1_9c yields: ... gpasm -c -DDEBUG_MODE=0 -DSTACK_HEAD=0x37f -DSTACK_IRQ_HEAD=0x33f -I mios_wrapper mios_wrapper/mios_wrapper.asm -o _output/mios_wrapper.o user_vectors.inc:13:Error [131] Processor type is undefined. user_vectors.inc:15:Error [131] Processor type is undefined. <repeat for a few 100 lines :( >... Thanks in advance for any advice or pointers to wiki pages I've missed. ;)

The pdf is great - just discovered it after building my first core module ;) and would've saved me some time and a lot of uncertainty along the way. Great stuff!

Hehe, only a couple of times - no permanent scars. :)

I finally got XCode compiling the skeleton application without any errors this morning while eating my cornflakes. I had to copy the tools folder into the XCode project root and then it worked fine. Thanks again for the fast help. Am constantly impressed with this forum. 8) 8)

Excellent - thanks for the fast fix! Now I get 2 errors when I build - which I am counting as a success as at least XCode is doing something! Cheers! :)

Hello hello again, I discovered all the lovely info in the wiki today and have been trying to set up XCode on the Mac to build the skeleton C file. But I feel there is some key information missing - so I'm a bit stuck. I'm following this page: http://www.midibox.org/dokuwiki/how_to_use_xcode2_as_ide_on_a_mac I'm really confused about what follows "you’ll find now: ... type this:" Is there some information missing here? When I do "go to “Project > New Target†and choose “Shell Script Targetâ€. Name the target “Makefileâ€" then I get a pop-up window in XCode asking the Target Info - what needs to go in here? If I just close the Target Info window, when I do "open the Target-Tree, open the target “Makefile†and double-click on “Run Scriptâ€" then I get another pop-up window asking the Run Script Phase Info - what needs to go in the script window? Thanks for any help here! System: XCode: 2.4.1 OSX: 10.4.11 (Intel Mac)

Hey thanks for the tip Thorsten, MidiPipe works very nicely! Cheers!

Ah, cheers for the confirmation. Ok, will think about what else I can use to send the mod wheel data...

Hello hello, I'm currently testing my Core + DINX4 using the srio_interconnection_test_v1a application. To test the voltages I need to send mod wheel value 0, 1 or 2 out to the core. Now I've found that the mod wheel on the built-in keyboard in MIOS Studio jumps over value = 2. It goes 0,1,3,4,5. Never 2. I have tried controlling the mod wheel via mouse and via cursor keys. As a work-around I connected an external midi keyboard instead, but that only sends out even values 0, 2, 4, 6... ::) ;D So, I was just wondering whether the MIOS Studio keyboard skipping 2 is a known-issue? Is there a way around it - e.g a keyboard short-cut to fine tune the mod wheel? Am running MIOSStudio_beta7_5 on MacBook Pro (OS X 10.4.11).

Thanks - I tried this one already for the SR/RC voltages, but must've missed the bit about testing the individual DIN inputs. From reading the main.asm I get the impression that, for this application, I have to trigger the clock "by hand" (using a modulation wheel signal) to pump the data out of the registers? Or, if I set the mod wheel to 0, will the application automatically clock out the data to the core? (I guess I also need to go and edit the asm a little to make the most of my 2x8 display, so that I can actually see something meaningful :) )

Hi, So I have my core + LCD (albeit the tiniest LCD in the world) + DINX4 all built and connected. lcd_interconnection_test_v1a runs fine and, as far as I can tell, passes. srio_interconnection_test_v1a runs fine and the correct voltages are measured in the correct places. Now I would just like to connect some switches to the DINX4 and see that I get a Midi signal back in MIOS Studio. I tried downloading midibox64/midibox64e, but I get the usual tidal wave of messages back from the core - is this due to the open AIN connector? I was wondering whether there is a standard, simple, DINX4-only test application lying around somewhere, or do I go in to the code and create my own? Thanks in advance for any hints...

Hehe, yeah, I know ;D - I searched on here for 2x8 LCD, but no real results, so I thought I might as well just try it. The core connector layout made it nice and easy. All that continuity checking on the core has paid off so far... :)

I got some time to connect the LCD module last night and it works first time. DIN module up next and I may do another video for that - might aim for sub 2 minutes. :)

Just picked up the new Ellen Allien album "Sool" - and it's great. I noticed that one track is credited with co-production by SmashTV. Is this the same Smash TV from midibox fame? Either way, the track is great! :)

Cheers for the replies and explanation. Ok, so I'll just leave them where they are then...

Hi all, So after building my first core module in record time ( ;)) I was wondering about the bypass capacitors. According to http://ucapps.de/mbhp_core.html: C7, C8 100nF The additional bypass caps have to be placed on the bottom side of the PCB, as close to the power pins of the PIC as possible. ...but in all the photos on the same page the caps are on the top side of the PCB. I did a quick search on the forum for "bypass", but didn't find anything obvious. Is the cap placement important?

Cheers for all the nice comments. It's my first midibox attempt, so the actual time was 3-4 hours spread over 2 evenings (in between watching the Euro 2008 football :) ) All the great documentation and pictures on the ucapps site made it very easy to build the board - thanks! Edit: actually, most of the time was spent twisting various items in and out of the pcb drill holes as many of the holes were too narrow for the intended device. I wonder if this is common, or just in the summer ;) :)

Enjoy! :)

Extremely cool!

Cheers for the welcome folks! Looking forward to posting photos of my first successful project - hopefully sometime in the not-too-distant future!

Just wanted to say hello to you all. The whole site and wiki looks really great, hugely informative and helpful - can't wait to get stuck into it with my first project... :) Fingers crossed I don't have to bother you too often with newbie questions... ;) Greetings from Berlin!
