Hi, ok,I`ll check the wiring once again.I´ll search for solder blobs and shorts too... Is there maybe a different display driver needed for the optrex? Or do I have to change the code somewhere? Greetz Brother303

Hi Stryd, thx for the answer. VEE was the only thing I had left to solder,so I think it`s VO. Backlight is working fine,the only characters I see are black blocks in the upper row. I`ve tested it with 2 different (and working!!) cores,one V2 with a SID-application and one V3 with fresh uploaded Mios. I spent on testing the whole weekend now with the result that I`m totally confused now. I had an old 2x16 Displaytech here and hooked it up just to see what happens. And guess what,it worked! All fine,with both cores,and with the lcd-test tool of MiosStudio I was able to write and send messages to the display. After that I hooked up a 4x20 wich results to the following display entries (with a mbfm application uploaded): Gns.>k>Rvcj-Ncog"" KoC"3">3>C""3>Rjofgs ??? After switching back to the 2x16 still the same entries,and what confuses me most,on both cores!!!(One Sid and one fm application) The wiring is absolutely correct,triple checked this! :'( Any ideas?

Hi all, I have posted this question in the optrex bulkorder thread,but here is a better place I think... I hooked up my display on a tested and working core v3 yesterday. But sadly it doesn`t works! Here is my wiring,could some of you guys here confirm that the wiring is ok please? Optrex - Core 1.VSS - VS 2.VCC - VD 3.VEE - V0 4.RS - RS 5.RW - RW 6.E - E 7.0 - 0 8.1 - D1 9.2 - D2 10.3 - D3 11.4 - D4 12.5 - D5 13.6 - D6 14.7 - D7 15.Cathode - B- 16.Anode - B+ Anything faulty here?!? ???

Hi Styrd,hi Nebula, good help,good link,thanks lot once again! ;D Greetz Brother303

Hi Nebula, can you (or anyone else) please give me a hint how to wire the display to the core. There are 3 points I`m a bit confused : The Optrex datasheet says VSS,VCC and VEE. To wich points on the core they should be connected? Every thing else is pretty clear... Thanks lot! Greetz Brother303 :)

hi styrd, I didn`t finish the mbfm so far,so i can`t check if it still works right now. Think I´m going to upload the application and check first. Anyone else any experiences with this issue? Thanks lot... Brother303

Hi everybody, yesterday I accidentaly put +/-9V on my opl-pcb for about 5 seconds until I noticed my error. The opl-chip got pretty hot,the yac512 stayed cool. My question is: Is there any chance for the opl3 to survive that accident or should I desolder it and put in a spare? And what about the yac512? May they be damaged too? As I mentioned above,these chips stayed cool. ??? Any suggestions? THX Brother303

Hi Stryd,hi Wilba, thanks for the information,think it`ll help! Cool! ;D Greetz Brother303

Hi to all, just started building a mbfm. I want to put it into the same pactec-case as the mb6582 with a frontpanel from Schäffer. Now I want to know if it`s possible to run the fm with a 4x20 display instead of a 2x40. Any drivers required? Or change something in the asm? Thanks lot! ;D Greetz Brother303

Goblinz, did you receive my paypal? I miss my name on your list posted above... ??? Greetz Brother303

Hi, Brother303 - 1Display (Germany) THX lot! ;D

Hi Nebula, have you sent the paypal-invoices for the overseas-orders yet? didn`t receive anything... :( Cheers Brother303

Also paid!! ;D

Hi, I`ve ordered the transparent ones,but the grey ones are fine too. PM sent! Cheers... ;D Brother303

Hi Smash, I`m in for a complete base pcb kit with pics. Thanks lot! ;D Brother303

Hi, I`m in for a set of the alternate design. Looks great! ;D Greetz Brother303

Hi Seppo, really nice work! Count me in for one please. This is exactly what I´m looking for to control my ASM-2. Great! ;D Greeeetz Brother303

Hi Altitude, as I mentioned above,count me in for one display. I`m interested in the CFAH2004A-YTI-JP. Greetz Brother303

Hi, if this offer is for the european builders too,count me in for one! THX Brother303

Hi, please count me in for one case. I`m located in Europe. THX! ;D Brother303

Hi, as I mentioned above,count me in for the base pcb and if possible for a control surface pcb! I´m interested in a group-buy too. Any group-buy activities planned for the housing and/or the frontplate? Greetz Brother303

Hi there, great work! If possible count me in for the pcb. THX! Greetz Brother303

Hallo, erstmal danke an alle für die Infos. Nur weiß ich jetzt immer noch nicht mehr als vorher... Wie habt ihr den die Presets aufgeladen? Midi-Ox? Serge? Bitte einmal eine genaue Beschreibung des Vorgangs,vielleicht habe ich nur nen ganz blöden Fehler gemacht oder was übersehen... Danke nochmal an alle! :)

Hallo, in Mios Studio sehe ich,wenn ich auf Sys gehe,einfach nur den Schriftzug "todo",kann aber keine Files öffnen. Mios und die Sid-Applikation gingen problemlos drauf...
