It would help if you explain exactly what you are trying to do? IIC (or I2C) is an industry standard serial bus that is used by many different microprocessors to talk to peripherals. http://en.wikipedia.org/wiki/I%C2%B2C The MIOS_IIC_* functions are described the functions list: http://www.ucapps.de/cmios8_fun.html Cheers Phil

Ah yes an easy mistake to make (although not usually when mounted horizontally :) ) Phil

Further to nILS' post, if you do write a detailed description, you may find somebody with programming experience who thinks "I could use something like that" and will partner with you to create it. Cheers Phil

For those of us that haven't seen your pics, what was the problem??? Cheers Phil

I have been through exactly the same thing with Donberg. I don't think that they have any SID's unfortunately, I guess that they just list them on their website and then try to source them when needed! Phil

That's quite a good price, I will let you know how I get on when mine arrives :) Cheers Phil

It doesn't really matter which, once you disconnect one of the leads, other components will not affect the test results. It is difficult to say but yes 770mV sounds like a likely forward-bias voltage for a standard silicon diode (germanium diodes have a lower forward-bias voltage of about 300mV) but who knows what effect any other components in the circuit are having on the readings? Cheers Phil

I always use a mnemonic that I learned at college in the 80's, unfortunately in today's world I would probably get arrested if I posted it in a public forum :) Phil

It is not really possible to test diodes 'in circuit' as other components will affect the result. You should really disconnect one end of the diode for proper results. Once you have done this, select diode test mode and when the diode is forward-biased (+ probe to anode and - probe to cathode), if the diode is working correctly the meter should show you the forward voltage drop (usually about 0.6 - 0.7v). When reverse biased (probes swapped round) the meter should show "open circuit". If you get a reading on the meter in both directions this means that the diode is faulty!

I never got anywhere with LFN support either. I then thought to myself, how useful is LFN for MIDIbox anyway? and decided (for me) not very :) Have you created a Unicode code conversion function and selected a code page as described here Cheers Phil EDIT: Also take a look at this post in the FatFS User Forum: http://elm-chan.org/fsw/ff/bd/?show=766

I didn't post before as I was bidding myself and didn't want to end up in a bidding war with another MIDIbox user but there has just been an auction on Ebay of 29 NEW (old) 8580R5's. The final price was £875.00 (998EUR) !!! The guy says he found the tubes in his loft and thought that somebody might have a use for them. Personally I think they have probably paid a bit over the odds as individual (tested) ones sell occasionally for about £25 each. I was probably being a bit hopeful with my maximum of £350 :) Cheers Phil EDIT: Here is the link http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=150539424415&ssPageName=ADME:B:EOIBUAA:GB:1123

Ohms law to the rescue..... To get the resistance required to generate 300mA on a 5V supply, you divide 5(V) by 0.3(A) which gives you 16.6Ohm's. The power required (in Watts) can be obtained by multiplying 5(V) by 0.3(A) which is 1.5W. If you put equal value resistors in parallel, it half's the resistance and doubles the power handling capacity so you could put 10 x 160R 0.25W resistors in parallel which would give you 16R which would produce a load of 312mA on a 5V supply. You could probably get away with 5 x 80R but they might get a bit warm :) Edit: The actual formula is: 1 R(total) = --------------------------- 1/R1 + 1/R2 + 1/R3 + 1/R4 ... Cheers Phil

Ermmm... I think that this is spam and I hesitate to click on the download link :) The "Correct" site for VLC is http://www.videolan.org/ Cheers Phil

Hi. If it is for the MB-6582, that can support any of the SID variants with jumpers to select which voltage to use (and the correct PSU option). I can understand why you would want 8580's or 6582's though! Cheers Phil

Hi Matthias. You and me both..... People are tending to hold on to 6582's and 8580's nowadays. You might have to settle for 6581's as they are more widely available. Worth checking Ebay periodically though. Cheers Phil

Hi. I did the same a few weeks ago, for 100 off the price is 0.60EUR each (this is for the clear version but I assume the price would be the same for other versions?) Cheers Phil

With all due respect, I know pretty much nothing about the MIDIbox SID but I found the answer within a few minutes. You must have missed the "Lead Engine" chapter (on a separate page) http://ucapps.de/midibox_sid_manual_l.html which details exactly how to do what you are asking. You may have noticed the "n" icon on the sammichSID PCB's when you were building it, nILS has made a massive contribution to this community and doesn't deserve to be called a "dickhead" especially as he gave you the answer just not the one you were hoping for..... Phil

Oh "Warehouse", I must have mis-read the post as I had visions of nILS in his pimp mobile :) Phil

Hi. Hopefully Jonathan Farmer who did all of the work on the Digipot interface will respond but I would guess that something like this should work: You will need to "#define DPOT_SPI 2" to use J19 SO of J19 connects to SI of the first MCP42XXX SI of J19 connects to SO of the second MCP42XXX SC of J19 connects to SCK of both MCP42XXX RC1 or RC2 of J19 connects to CS of both MCP42XXX (#define DPOT_SPI_RC_PIN 0 or 1 ) You may find more information about this by reading the source code in %MIOS32_PATH%/trunk/modules/dpot and %MIOS32_PATH%/trunk/apps/tutorials/026_dpot directories. Cheers Phil

To be honest, without knowing the internals of the keyboard, I would have said this would cost more than say a simple alternative keyboard with MIDI out. Considering that you would need at least a CORE8 and 2 x DINx4 modules to MIDIfy the M-Audio when you add the amount of time that you would need to spend, unless you are doing it purely to learn about MIDIbox I would get something like this which is available for less than 95 euros! Cheers Phil

Hi Tim. Is there any likelihood that you will add the MB-6582 boards to the "EU Low value order page" ? At a price of $20 their value would be below the £18 threshold that HMRC have set to qualify for Import Duty and VAT relief. I'm not sure if this would exceed the maximum size for flat packages but could save me quite a bit as I always seem to get hit for Duty/VAT. Yes it looks like I might finally be thinking about building something with a SID in it :) Cheers Phil

If the X32 lives up to the hype then it does look like a great desk, I had better start saving :) Judging by the picture, they obviously haven't quite finalized the design yet..... Sorry to hear that your DDX3216 is poorly, from what I have heard, they are usually pretty reliable so hopefully it is just a simple PSU issue? Cheers Phil

While MIOS32 is (in some respects) the future, MIOS8 is far from dead. If you want to build a MIDI controller and you don't want to write your own code then to be honest, MIOS8 is still the way to go. The MIDIbox 64 and it's brethren are complete and fully working controllers which can be fairly easily adapted to most needs without any programming. Having said that, if you are like me and enjoy spending more time building and programming than actually using the kit then I would definately recommend going the MIOS32 route. Be aware though, there is no MIDIbox 64/128 type project for MIOS32 yet so you would need to create your own or adapt one of the sample apps. Be warned though, this route can include much pain and not a lot of music :) Luckilly every module that you buy will work with either CORE variant so why not start with the CORE8, get a nice working controller and then in the future you can always upgrade to a CORE32. To be honest, if it is just a MIDI controller for Ableton, unless you want to play with OSC and other more advanced features then you are unlikely to ever outlive the CORE8. Cheers Phil

By the way, the correct HOWTO for MIOS32 toolchain setup is: http://www.midibox.org/dokuwiki/doku.php?id=windows_mios32_toolchain_core&s[]=core32 It may be worth starting again using this? Cheers Phil

Which toolchain are you using? The current recommended one is the CodeSourcery 2008q3-66 release from www.codesourcery.com Is the toolchain also installed on drive D:? you might try having everything on the same drive (preferably c:) and remove the drive letter from MIOS32_BASE as that may be confusing make? Cheers Phil
