  5. MDIO128 connections

    in MIDIbox HUIs

    Posted · Edited by chapelier fou

    Thank you for the picture.

    Sadly, you don't seem to have the same core as me.

    And one thing bothers me : how could you possibly chain a DIN to a DOUT ?? SmashTV's doc is really clear about it : DINs can be linked to DINs, and DOUTs to DOUTs....

    I'll be out for three days, i ll try to get in touch with Tim from SmashTV

    Thanks again

    That the connector i've tried. Sorry but i still don't get it.

    Let's see :

    a 10 (2*5) connector in the J8/9 of the core. No prob. But then, one half of the wires go to the DIN chain and the other half to the DOUT chain, right ? So it makes 5 and 5 wires, but going to 10 and 10 connectors. i think one row is useless in the J1 DINs and DOUTs connectors ?

    A photo would be great of course.

    Both DOUT and DIN go to the J8/9 connector of the core, right ? 5 pins for the DIN and 5 for the DOUT chains, right ?

    But on my DIN and DOUT modules, the J1 connectors have 10 pins, not 5.

    Hi,

    i've mounted my core, my 4 DIN and my 4 DOUT. I installed the MIOS32 bootloader. And (unless i am wrong) i've loaded the basic MIDIO template with the MIOSSTUDIO. So i thought i was ready to do some tests. But :

    The J1 on DOUT and DIN are 2*5 pins, but on the schematics, they are supposed to be 1*5. What's the reason for this ? So which rank of pins should be used ? Can i find somewhere some pictures of detailed inside of midio128 ? i'd like to know an elegant way of pugging all these.

    (on a side note, as a newbie, i plugged the 2*5 J1 of my DIN to the 2*5 J8/9 of the core, to make tests....this resulted by heating the ICs on the DIN, could the be broken ?)

    Thank you.

    I'll come back very soon with new problems, but believe me, i am doing my best.

  14. A few question on making the Core LPC17

    in MIDIbox HUIs

    Posted · Edited by chapelier fou

    Thank you Tim !

    for 1. Let me rephrase it : where should i put pin 1 ?

    for 2. i have no idea what JTAG is, so i think i'll go for the first version (like in the pictures)

    for 3. i figured it out in the meanwhile !

    for 4. ok i'll try again....

    for 5. makes sense

    Thank you again for everything !

  16. A few question on making the Core LPC17

    in MIDIbox HUIs

    Hi again,

    i having several questions :

    1. I dont know the polarity of IC4 and IC5. They have just one dot (i think marking the first leg)

    2. check out the picture showing the bottom of the LPCXpresso's bottom. Ok for the two 27pins SIL headers. For the right side it's said "one 2x6-pin DIL header and a 6-pin SIL header for the right side" but obviously on the picture it's SIL headers.

    and for the left side : has it to be soldered on the main core board ? Or just putting headers to connect the debugger is enough ? (on picture 8 of the soldering guide of the Core, no DIL headers are put).

    3.The J17, J15_S, J27 jumpers : maybe the parts provided by avishowtech are wrong, but i have no idea on how to deal with them.

    4. The X1 component : the legs are too big to fit in the holes, should i enlarge the holes ?

    I hope i am clear, sorry for these questions,

    and thank you

  22. Big Led buttons controller

    in MIDIbox HUIs

    Posted

    Hi everyone,

    i am brand new on this forum, so hello !

    I want to make a MIDI controller, preferably USB wired, with only buttons with leds in it (those from sparkfun i think). Lets say a big launchpad. Bidirectional communication and single color leds.

    Around 90 buttons, i guess.

    Any help on what i will need for this would be greatly appreciated !

    i am lost in all this midibox thing right now, but i have no fear and i am prepared to suffer !

    Thanks,

    louis
