The problem was indeed that my RNs were not fed with 5V.... Thanks to all of you for helping me spotting the problem ! Everything seems to work like a charm now...Waiting for my frontpanel to buil the enclosure and send some pictures on the forum ! Cheers dudes !

Problem solved Guys !! Thanks for the troobleshooting ! My RN common pins were missing a 5V feed.....Now everything seems top work (well...I'll dig that in detail from now on but the Frontpanel is responsive ) Thanks again !

Resistance between common pin of the RN and each other pin is 10k. I'll double check the schematic tomorrow..and send pictures as soon as possible.. Thanks guys

Oh and what does exactly mean "isolated network" ?

I used these ones: SIL 6-5 10K

Thanks for the schematic ! I've been looking for it over and over without finding it... Seems like none of my RN common pins are connected to 5V....Must investigate this !

Ok....RN solders seem fine, continuity is fine with the IC pins too.... There is continuity between all ground pins of the RN, but no continuity between RN ground pins and CS board ground....For eg, there s no continuity between C1 "negative pin" (I know C1 is not polarized but this pin is connected to IC 1 ground and thus to CS board ground) and common pin of RN1... I'd like to know if this Is this normal before soldering a cable to have continuity between RN common pins and CS board ground and potentially ruin my MB even before it has worked ! The 1 000 000 000 $£€ question is: Do all resistor network common pins have to be connected to CS board ground pin ??

That's the one I uploaded via MIOS

Hi Folks ! My LCD problem is solved, my E131 sd card problem seems to be solved......No I'm facing a wilba frontpanel problem... I created the attended directory tree on the SD card: - file MBSEQ_HW.V4 (Wilba's one) at the root of the SD - directory SESSIONS and DEFAULT session created via MIOS terminal Booting the MB lead me to this weird screen: G1:Unnamed G2: Unnamed G3: Unnamed G4: Unnamed NoCat 1: A1 _ _ _ _ NoCat 2: A1 _ _ _ _ NoCat 3: A1 _ _ _ _ >>> NoCat 4: A1 _ _ _ _ Typing sdcard tells me there is no MBSEQ_BM.V4 at the root. So I copied the /SESSIONS/DEFAULT MBSEQ_BM.V4 at the root of the sd and I now get this screen: MIDIbox Seq v4.092 1.1.1 /SESSIONS/DEFAULT 140.0BPM Bookmarks About this MIDIbox< Open Save SaveAs New Delete Info The About this MIDIbox< is slightly flickering on the rightmost of the left LCD display... Anyway...I'm pretty sure the wiring is correct but I can't get out of this screen, whichever button or encoder I press.... Could this non responsive frontpanel come from a badly tuned MBSEQ_HW.V4 file ? Which options have to be modified for a "traditional" wilba's frontpanel (with beat led) and no tpd setup.... Cheers, Tom.

OK, I think we can consider the SD card Problem solved since I now get a default screen when booting up my MB seq. The solution was : - to copy wilba's MBSEQ_HW.V4 at the root of the SD card file system - to create the /SESSIONS/ directory then create a DEFAULT session using MIOS terminal. See you in my next post....

OK, no more SD card error after your tips EsotericLabs. Thank you. Now, when booting up my MB, the LCD display this page: G1:Unnamed G2: Unnamed G3: Unnamed G4: Unnamed NoCat 1: A1 _ _ _ _ NoCat 2: A1 _ _ _ _ NoCat 3: A1 _ _ _ _ >>> NoCat 4: A1 _ _ _ _ Is this normal ? No matter which button I push, no response from my MB...

Ok. I formated the SD card via MIOS studio...still no luck ! The same error message appears and I can't do anything...

Hi folks ! Now that my LCD display work fine, I'm trying to get my wilba frontpanel to work... Precision: everything is soldered on the CS pcb, except the leds (I'm waiting for my frontpanel to be delivered).... When the CS pcb is NOT plugged in, I don't have any error message whether I put standard's, TK's or Wilba's MBSEQ_HW.V4 at the root of my fat 32 formatted SD Card. Turning the MB on leads me to the main page as shown here . With the wilba's MBSEQ_HW.V4 at the root of my SD card, when I plug the CS PCB (from J1 on the CS PCB to J8/9 on core module), I get this error: >> |!! SD CARD ERROR !! |<< >>| E131 (FatFs : D 0) |<< I learned german at school, but this is kind of a long time ago, so I may have misunderstood this discussion . : TK said: "E131 steht fuer ein ungueltiges Bank Format (irgendetwas stimmt nicht mit den MBSEQ_B*.V4 Files in Deiner Session)" This E131 means there is something wrong with my MBSEQ_B*.V4 in my session.....The fact is that my SD card only has the MBSEQ_HW.V4 at the FS root....No /SESSIONS directory or else...When I type sdcard in the MIOS termial, I only get MBSEQ_C.V4 and MBSEQ_HW.V4 files listed as valid (the output of sdcard tells me there is no /SESSIONS/DEFAULT/ files etc.) The previously quoted topic talks about a D9 error.....but I get a D0 error....and no luck with any search in the forum or the web... Any idea of what could have gone wrong ? Cheers, Tom.

Yes ! My New Haven LCD displays work fine....so ST7066U controller is HD44780 compatible ! Now I get another problem, but that will be in another topic ! Thanks everybody for pointing me to the RN error... Cheers.

Can anybody tell me if I can modify the title of the thread to add a [solved] ?
