If you look at this diagram: http://www.ucapps.de/midibox_sid_cs/mbsid_v2_din_default.pdf if you had the menu encoder, menu button and select #5 connected to J6 (instead of J4), you would get this behaviour.

This sounds like the DIN table is not configured correctly. i.e. the menu button is connected as the "SID 3" button. Which wiring are you using to connect buttons to the DIN module? Which .hex file are you uploading?

Mode/Sync LED isn't being used yet. Osc Control/Knob is actually Osc Asn in the diagram (I changed the artwork label but not original pin assignment table). Find attachment which is an updated LED matrix test, which should work the same as the original LED matrix test but with the MB-6582 configuration and control surface. I hadn't realised until I ran it that it doesn't just show one LED at a time but sort of a trail of the last 8 LEDs turned on. It's easier to just look at it than explain it. It only shows LEDs in the 8x8 modulation matrix, not the other LEDs which are also in a LED matrix (all LEDs are being multiplexed by the last DOUT with the transistors, half are in the modulation matrix, the other half are in the rest of the CS). I'll work on another test app for showing all the other LEDs too. mb6582_led_matrix_test.zip mb6582_led_matrix_test.zip

If it is only one row of the LED matrix at fault, then other horizontal rows are working, and LEDs outside the matrix, so thus the current sinking is working, and the current output of the first 74HC695 is working for the other pins. So the problem MUST BE somewhere between U21 pin 5 and the start of that connection to the row of LED anodes which is to the right of the matrix. It could be on the base PCB, or in the cable, or on the CS PCB. Test between the IC pin itself (from the top) to JD6:D5 on the base. Then from JD6:D5 on the base to JD6:D5 on the control surface PCB. Then from JD6:D5 on the control surface PCB to the third row of LEDs... this is visible from the bottom as a horizontal track going through the LED anodes.

ML-303... *drool* I would trade my MB-6582 for one ;D

I suggest Doug proceed with arranging a bulk order, instead of everyone annoying this guy with quotes for one. Even with this recommendation for the C-1004, it's best to check one before buying a lot. "Terminated in DIN type plug" sounds promising though and if I was in the U.S. I'd buy one to check... unfortunately they are no good to me here in Australia with 240V mains, even after swapping the power plug ;D Also this link is for a C64 PSU, found it in the "COMPUTERS - COMMODORE PARTS & EQUIPMENT" section: 9VAC/6.7WATT & 5VDC/7.5 WATT SET TOP TRANSFORMER 9VAC/6.7W & 5VDC/7.5W.

Not even CMOS datasheets are consistent... every 74HC165 datasheet I've seen uses Vcc/GND not Vdd/Vss. (If you find one that doesn't, please post a link here!) I can see how this can be confusing to newbies now... The PIC has Vdd=5V, Vss=ground. J9 has Vdd and Vss pins. J9 connects to DIN module, which also has Vdd=5V, Vss=ground. So far so good. Now look at a 74HC165 datasheet, it has Vcc/GND. Maybe we need to link this somewhere in the doco: http://encyclobeamia.solarbotics.net/articles/vxx.html

Cool... Something about this photo makes me think it's mounted to a wall!

I am intrigued how a newbie knew they needed to connect switches to ground, when I find no explicit mention of how to connect switches to the DIN module other than this diagram, which doesn't use the term ground. ???

This diagram shows connecting all the switches to J5:Vs or J6:Vs I don't see what the problem is. ???

I fit in two categories though... I still use MPASM sometimes, and adding features to MB-SID is done in MPASM, but it's easier to develop new code with sdcc.

It depends on the addresses of the 24LC512 (or 24LC256). You do not need to have 8 chips, you can have two, one with address 0, the other with address 7 (see A=0 and A=7 below): The difference is in the A0,A1,A2 pins, for A=0 they are all 0V, for A=7 they are all +5V.

Thanks nebula, that's the gap between bottom of knob and top of the encoder, I can work out the rest.

and it was so close... stryd, why don't you self-moderate and get this thread back to one post? ;D

Are you saying pins 22 and 28 (or pins 22 and 25) of the SID chip are shorted inside the SID chip? Vdd of the SID chip is +12v or +9v, different to Vdd of everything else (+5v). Vcc of the SID chip is +5v. Just a bit confused, if you think the SID chip arrived dead, or your PCB was at fault.

Thanks for the photos, neb... any chance you can measure the exact dimensions of the knobs when fully pushed onto the encoder? eg. base of encoder to base of knob? Actual knob dimensions I can get from a datasheet (where be that anyway?) but what's typically missing is the distance between top/bottom of knob and the PCB (and thus indirectly the top of a panel).

6581s can work for a few minutes at 14 volts and then die. :'( I am ashamed to admit I know this from first-hand experience. :-[

Don't your LEDs have a flat side?

I agree... don't use MB-6582 as a reference design, it is only by pure luck (and countless hours of rearranging tracks) that I was able to fit it onto two boards that would fit in a PT-10 case. If a control surface is not as compact as MB-6582 then it makes much more sense to put the DIN and DOUT modules on the same PCB as the control surface components. Then again, I'm probably going to repeat the same mistakes and aim for a 14" wide MB-SEQ control surface PCB and probably have to put the DIN and DOUT on a second PCB. ;D

You need to provide more information. You are using Option C? I have not specified exactly what is required to use Option C. What bridges and extra wiring are you using? How is the LCD not working correctly? If it is missing backlight, this is due to missing track. http://www.midibox.org/forum/index.php?topic=9781.0 Upload might not work if you do not have a jumper in J11 http://www.midibox.org/dokuwiki/wilba_mb_6582 (scroll to bottom). SIDs get warm, that's normal, even 6582 SIDs get warm, but you should not be putting SIDs in sockets until you do a full test of everything, voltage checks, uploading MIOS and MB-SID app. Inserting the SID is the ABSOLUTE LAST THING you do.

There's this wonderful thing called Google, have you heard of it? ;D http://www.technick.net/public/code/cp_dpage.php?aiocp_dp=pinconmis_c128_power

Did you see this first? http://www.midibox.org/users/jim_henry/building_a_midibox_lcd_cable.pdf

If you need a power switch for your MB-6582 PCB, look here: http://www.midibox.org/dokuwiki/wilba_mb_6582_power_switch_bulk_order These come with SmashTV’s parts kits already. I kept a few back from my delivery of 400 switches to SmashTV, so I can share them around to those in need, mainly to those crazy Europeans who like to rip apart a C64 for this switch ;D Don't do it! I have new ones! Sorry I couldn't offer these sooner and ship them with SIDs etc., but it took a long time to find a cheap supplier, and then waited for SmashTV to start selling his parts kits with them (to avoid people buying more than they needed unnecessarily). Remember, don't post "I want one" here, go to the wiki and add your name to the list! http://www.midibox.org/dokuwiki/wilba_mb_6582_power_switch_bulk_order Let's see if we can have a one-post bulk order thread... ;D

This is brother303's design, not mine ;D
