Search for the following code in main.asm: and replace 0x09 by 0x0A. Raphael

That's right. You have two possibilities: 1. Add the resistor between GND and the Fader tap (the one which is connected to the AIN) and you will get an output of 0 if you dont`touch the pad. 2. Add the resistor between +5V and the Fader tap (the one which is connected to the AIN) and you will get an output of 127 if you dont`touch it.

How about connecting a 10k resistor in parallel?

There are two USB interfaces: http://www.ucapps.de/mbhp_usb.html is very reliable. I've built already two of them. The development of the easier to build USB-PIC interface (http://www.ucapps.de/mbhp_usb_pic.html) is constrained by a buggy PIC. So there is a working solution, but you will have to solder a multi-pin SMD chip. Raphael

Depends on how clever and experienced you are ;) If you're a beginner, a LCD will be veeery useful! mhhh... have you ever looked for "USB" on this site http://www.ucapps.de ??? Yes, but only for about one or two hours or so (never tried it) Raphael

If you leave 2 4051 out (e.g. IC3 and IC4) clamp the appropriate pins of J5 to ground (A2 and A3). No need to ground J3 and J4. Raphael

Ja, 2 sind genug ;D Es sind aber evtl. 100nF Kondensatoren. Die findest Du zwar im Schaltplan anber nicht auf der Platine. (Bypass Kondensatoren, die auf der Platinenunterseite verlötet werden.)

So I will say it again: Build two cores and link them like Illogic described for you! With two linked cores you won't need any programming skills. To do the configuration in most apps the only thing you will have to touch (if at all) is main.asm. Read the comment in this file. Hey Illogic: He plays bass guitar... (from his first post)

Illogic is right. If I remember my lectures in basic electronics correct 11V AC will give about 15V DC after the rectifier. So your regulator will even get hot without a big load like a LCD backlight. Raphael

If you don`t give your credit/EC card number they will send the package "contre remboursement" (as my dictionayry says). Just give em a call. I'm shure they have also english speaking guys. Raphael

Da scheint mir der PIC tot zu sein >:( Alle anderen Spannungen liehgen auch auf 5V, wenn kein PIC gesteckt ist. Der TX-Pin hat nur mit (funktionierendem) PIC 5V. Du solltest auf alle Fälle die Verkabelung zum SID und die SID Platine 10x genau anschauen, bevor Du es nochmal probierst.

It's described here: http://www.ucapps.de/mios_bootstrap.html Same procedure as the MIOS upload (But only two seconds to start the upload - so use MIOSStudio with autodetection ;)). After MIOS is loaded you should see "READY" on the LCD. After the app is loaded you will see the application user interface. Yes, please don't install the SID until the interconnection test is OK. Afer that you can load the MBSID application (the upload will overwrite the interconn. test but not MIOS). As illogic has already written, the regulator gets pretty hot with a LCD connected (Backlight draws lot of power). Without a heatsink the 7805 willbe untouchable (up to 100°C max). I think up to 70°C are OK. Look at the datasheet. BTW.: What PSU are you using? A too high input voltage will cause a hot regulator! Raphael

I spoke of the "ÄTZGERÄT 1" which costs 99.95€ . That's a smaller on for PCBs up to 250x175mm. Enough for all the MIDIBOX stuff. "ÄTZGERÄT 2" (159.95€) is for bigger PCBs.

To get best results, Sodium persulfate needs a temperature around 40-45°C Ferric chloride works even at room temperature very well, with Sodium persulfate you will see (nearly) no reaction at room temperature (20°C). The heating has to be regulated because Sodium persulfate crystalizes out above 50°C. That's why the etching machines are more expensive. But you can get one from Reichelt (www.reichelt.de) for 99€. But for a delivery to France you will have to order at least for 150€ :( Raphael

MIOS can handle up to 128 digital inputs in general. This are up to 64 encoders (with no buttons) OR 128 buttons OR any mixture in-between (e.g. 32 encs and 64 buttons) So you will need 2 cores. One for the up to 128 buttons and one for the encoders and link them with MB_LINK: http://www.ucapps.de/midibox_link.html --> Still no progamming needed!

Ich lass mich ja gerne belehren, aber in 8 Tagen hats bei mir noch nie ne Sendung aus den USA geschafft. Rechne mal eher mit 2 Wochen (wenns nich blöderweise beim Zoll hängen bleibt)

Hi, From the MIOS site: - handling of up to 64 detented/non-detented rotary encoders - handling of up to 128 buttons, touchsensors or similar digital input devices See: http://www.ucapps.de/mios.html You should use the MB64E application which handles encoders (up to 64) and buttons (up to 128) and I think you won't need any programming skills because what you wanna do is just what MB64E does ;D Raphael

I was speaking of the instructions from the core site: What is unclear? IC1:MCLR(1) - IC1:Vss(12) = 5V says, that you should meassure 5V between Pin1 and Pin12 of IC1 (which is the PIC as you can see in the schematic). Please do all voltage checks without chips plugged! Otherwise: :( Raphael

Yes, it does!!! Look at the photos on the core page for right placement: http://www.ucapps.de/mbhp_core.html One side of the cap is marked with a (normally) white strip with printed '-' signs in it. That's the minus side ;) For the core it's all written on the core site: http://www.ucapps.de/mbhp_core.html For the SID, gues what? YES, on the SID site: http://www.ucapps.de/mbhp_sid.html http://www.ucapps.de/midibox_sid.html And again: It's al written on the core site (beside the photos): http://www.ucapps.de/mbhp_core.html Please reread everything on all the sites concerning core and SID. Raphael

You CAN use them for special functions (like all the other buttons). See midibox64_sfb_table.txt in the MB64 source for expanation of the functoios. If you dont need them, just assign any other event to them. All buttons (except the menu buttons and the snapshot button) are free assignable. Raphael

GPASM has problems with some macros. See this thread: http://69.56.171.55/~midibox/forum/index.php?topic=5171.msg32067#msg32067

rgoto  MACRO  label     bra   label     ENDM Where is it defined? Like all macros in macros.h ;D

How about Virtual PC? Ok, may be too expensive for just compiling some PIC assember files ;)

Soweit ich weiß, nur die 2 Kondesatoren C1 und C2. Hast Du dort etwa die für den 8580 eingelötet ;) Raphael

Muss man ja nicht einbauen. Kann man ja auch weglassen. Was muss man denn am Schaltplan ändern ??? Ich glaube Du hast das ganze Konzept der MidiBox nicht so ganz verstanden. Alles ist änderbar ;D. Die Bauvorschläge sind deshalb so wie sie sind, weil Thorsten seine Box so gebaut hat. Du kannst aber alles so ändern, wie Du es brauchst. MB16 wäre nur die richtige Basis für enen kleine Box mit 6 Encodern. Leute, die hier viel in zwei Sprachen antworten (wie mich) stört das aber enorm. Wenn ich im deutschen Forum antworte und eine Minute später feststellen muss, dass die gleiche Frage im englischen Forum schon beantwortet wurde, ärgere ich mich. :-\ Ausserdem bekommen die anderen ("einsprachigen") dann die Antworten nicht mit. Schade. Besser wäre, Du stellst die Frage zuerst auf english (da lesen mehr mit und eventuelle Antworten stehen mehr Leuten zur Verfügung) und wenn Du nach einer Woche keine Antwort hast, stell sie nochmal auf deutsch.
