OK, I think I see what to do.
Thank you for the reply :)

Hello,
I am soldering a MBHP_DOUTX4 V2, but I don't see clearly where to put the 4+1 caps on the board: the photo is not clear enough, and the caps are not mentioned in the Eagle board files.
Thank you for the help!

erm...32 bits

Hello,
These are the MBHP_DINx4 and MBHP_DOUTx4, so yes, they have 16 bits each one, and will test first a OUT module and 16 LEDs, then a IN plugged on that OUT, and check the output of the IN.
Why I cannot test with the core? Please take a bucket of pop-corn : because I destroyed the optocoupler yesterday (yikes, I punched it and broke 1 pin, it was very late, and I was nervous...), but I ordered one other. So, the MBHP_CORE seems working (at least it doesn't burn, and voltages are OK at the control points), but with the bare bootloader.
Meanwhile, I will solder the IN and OUT modules and test them with an Arduino.

Hello,
Can I plug the outputs of the DOUT to the inputs of the DIN modules, so that I can test them togheter through a serial line ?
My idea is :
- send 16 bits (16 clocks)
- send latch signal
- send load signal
- read 16 bits and compare
Will it work?

OK, I will try to find out.
For the moment I've written a "ebuild" that uses the binary package, and this is sufficient for now :)
Thank you very much for your fast, reliable and kind replies, I really appreciate.

Thank you very much !

Hello,
MIOS Studio (binary 2.4.6 for Linux) is too high for my small netbook display : 1024x600. Is there a way to reduce the height of MIOS Studio ? For the moment, I move the window to partly hide the virtual keyboard and I can use MIOS Studio.

Question #2: do MIOS Studio compile with JUCE 2 or 3?
-
Hello,
I would like to build MIOS Studio on Gentoo Linux, in 32 and 64 bits versions. I can get the SVN sources and so, build a "live" version, but is it also possible to get the sources related to the binary releases?
Kind regards,
Xavier Miller.

OK, that's perfect ! It's as robust as my Arduino platform :smile:
MBHP_CORE is soldered. Tomorrow, I solder the pins and power cable, and will test it ;)

Hello,
I am soldering a PIC-based core module and a SID module. The PIC has the MIOS bootstrap.
Then I will upload the OS.
I have a question: what happens if the upload fails? Can I upload the OS again without problem?
I would be sure not to brick my first MIDIbox project, so I need to be sure everything will be OK :smile:

... and I got the kits today :santa:
Just for St Nicholas :rofl:
-
Hehehe: packs from voti and midishop are sent... and a colleague will sell me a C64, that will be the power supply, control surface, and 2nd 6581 :)
A good present from "Saint Nicolas"

Hello,
I got a reply : Mike was in holidays.
I changed my order to add a second SID board, a colleage will sell me his brown C64, so that I have 2 6581 :)

I got that error:
The mail system <e***0@aol.com>: host mailin-02.mx.aol.com[64.12.139.193] said: 521 5.2.1 : (HVU:B2) http://postmaster.info.aol.com/errors/554hvub2.html (in reply to end of DATA command)I tried from 2 different email addresses (different domains), and got the same error. I will try with a gmail account.
EDIT: same error with gmail.

Hello,
I ordered some kits at Mike's site: http://www.mikes-elektronikseite.de/ and I would like to contact Mike to see how to pay that order.
I didn't got any answer from the webshop mail, and the given mail (@aol.com) don't seem to work again (mail blocked by AOL).
So Mike, if you pass here, you can contact me by P.M. ;)
-
Hello,
I ordered kits and parts from Mike's and Volti's sites :smile:
I feel like I was at 14-15 :santa: (the years of Elex)
EDIT: and for serigraphs, I will use laser decal paper.

Pour les sérigraphies, quelqu'un utilise des décalcomanies sur laser / jet d'encre

Le mot-clef est "Laser decal Paper" :)

Bonjour Pilo,
Merci pour cette longue réponse.
J'ai construit cette insoleuse avec du bois, une plaque de verre, et des ballasts et tubes TL UV. Je mettrai en ligne quelques photos.
Les achats aux States, j'évite un max, car en Belgique, on se chope une "taxe postale" pas piquée des vers : 21% de TVA + 10-30 EUR de "frais de présentation à la douane". J'achète de préférence en Europe ou Hong Kong.

Je profite de mon topic pour poser quelques questions de débutant.
- Durant mon adolescence (années 80), j'ai construit une insoleuse, et j'ai gravé quelques circuits à l'acide. J'imagine que les technos sont similaires à l'époque, et que je devrai me fournir en différents produits (couche photosensible, révélateur, acide).
- est-ce difficile de faire du double face ? Ou suffit-il d'être méticuleux ?
- est-ce qu'une machine à graver (avec chauffage et oxygénation) est vraiment un plus ? (je gravais en chauffant l'acide au bain-marie, et dans une petite bassine).
- Comment faire de belles sérigraphies sur les faces des boîtiers ?
- Quels sont les bons coins à Bruxelles, ou dans la zone Halle/Braine l'Alleud/Nivelles ? (Elak, Capitani, ...)
Bref, vu que je vais partir de PCB MidiBox, je me tâte à tout faire à zéro, ou à commander les PCB en Allemagne.

There is one for sale, but too expansive for me. I will build a MIDIbox SID.
[SOLVED] MBHP_CORE sends only 0xFF MIDI messages
in Testing/Troubleshooting
Posted · Edited by alchemist
Hello,
At my first run, the MBHP_CORE module sends only 0xFF messages in the Midi Out, and MIOS Studio cannot communicate with it.
I tested it in Windows and Linux, with 2 different MIDI interfaces : an edirol UM-880 and a "bad" ESI MidiMate II.
And I don't see anything on a 40x2 LCD display...
What can I check to find out how to find the problem?
Thanks in advance!
