I used the latest microchip software for the Pickit2 .. and it seemed to work at 3 volt .. all LEDs blink once 3-4 seconds after I power up the core

Hi guys, I am building my first seq v4 with the STM32F4 .. all boards from SmashTV. After soldering the core I added 2 Midi IO boards to J11E, uploaded the wilba hwconfig file and all worked perfect. 3-4 seconds after startup all LEDs on the Midi IOs blink one time. Now I added the line driver transmitter and a Quad IIC .. but sudddenly on startup only one or more LEDs of the Midi IO blink with no delay. I detached all elements from the core, only leaving the Midi IOs connected .. same .. short blink directly after power is switched on ..sometimes all, sometimes only one (last in line) sometimes 3 or 4 ... Switched the 2 Midi IO boards so that the second in line becomes first .... same If I connect a midikeyboard to the boards, the proper LED reacts perfectly ... but on Midi IN AND on Midi OUTS. The wilba panel is not yet finished, so I have no chance to check the menue for the midiports or send something. Do I have a short somewhere?? And why did it work multiple times before? Where should I start debugging .. is it the core?? Or maybe the STM32F4 itself?? Heeeeeeeelp

Hallo Jungs, ich bau ja grad meinen Seq V4. Als die beiden Midi IO boards fertig waren und am STM32F4 board angeschlossen wurden, blinkten die ganz LEDs ganz brav 3-4 Sekunden nach dem Start alle einmal auf. Jetzt hab ich den Line Driver Transmitter und das Quad IIC dran und hab heute sehen müsssn, das die LEDs nicht mehr aufblinken zumindest nicht nach 3-4 Sekunden. Bei Stromzufuhr blinken eine oder mehrere LEDs der Midi IO boards einmal kurz auf .. meist das Letzte, teilweise irgendwelche mitten drin ... 3-4 Sekunden später dann die LEDs des Quad IIC wie es sein sollte, bzw. vorher war. Wenn ich ein Midikeyboard mit dem OUT anschliesse reagieren die LEDs der Midi IO .. also sowohl die Midi IN als auch die Midi OUT. Zum testen das Quad IIC und den Transmitter wieder abgeklemmt .. es bleibt beim Selben. Jetzt hab ich natürlich Schiss, das da irgendwo ein Kurzschluss o.ä. ist. Hat einer von euch sowas schonmal gehabt?? Wilbapanel ist noch nicht fertig, daher kann ich leider nicht sehen, ob ich die Midi IO boards sehe oder ansprechen kann :( HWconfig file ist das von Wilba, war es auch schon die ganze Zeit ... HILFEEEEEE

After some configbattle with the Pickit2 clone (Vdd has to be 3 or 4 volt instead of standard 5) all 4 PICs for the of the Quad IIC are programmed. But I had to notice that at my 2 Midi IOs only 2 LEDs do blink on startup :( although 4 days ago all worked fine. I think it might be my SD card (I took a very old one from my ) or the the slot, so the hexfile is not read completely ... mor debughing soon ..

I got my Pickit 2 today and it does scan the PIC as 16f88. But when I try to write at 5 Volt VDD I only get Errors. It works at 4 volt and 3 volt ... is that o.k.ish too ?? For the Note, .. I never ever used a PIC Programmer befor .. :)

PICs still need the hex code ... now saving up money for the next partorder .. the mighty wilba panel

Just ordered a Wingoneer Pickit 2, hope this works too

Same problrm here now .. Quad IIC done ... PICs from reichelt ... unprogrammed ... Wich little programmer should I buy and where do I find the code??

Anogher little step further to my baby .... had a bit of panic cause the boards didn't work at first, but the only problem was, that I connected J11E to J2 of one board instead of J1 .. had one connection cable cramped wrong ..

On my way .. still some trouble with the MIOS that seems to have found some unsuported functions like LED_LIVE and LED_JAM_LIVE and some more

I always wanted to say this too ... Still some troubles with the MBSEQ_HW.V4 file Some functions are not supported by the MIOS .. at least that is what zhe MIOS Studio tells me. Like LED_move, LED_JAM_LIVE, LED_LIVE and some more, plus the BUTTON too ...

CORE_STM32F4 done .. it does blink, hope it works too

The TLV for the AOUT_NG arrived some weeks ago Today the electronic parts for the first pcbs came ... still have to get the parts for the wilba panel and the AOUT ... hope to find some soldering time in the weekend

Great work .. Chapeau

Keep in mind that if you use Acryl that has some transparancy, you do not need to cut all LEDs, simply place them under the acryl, zhey will blink through, saves a lot of money ;)

I just PMed him ;)

Hi jzurd0, If you find one, let me know, cause I search too. If not, and this is not superurgent, I will build my wilba this year with round buttons like this ... http://www.reichelt.de/Eingabetaster-Digitast-/DT-6-SW/3/index.html?&ACTION=3&LA=2&ARTICLE=7241&GROUPID=3280&artnr=DT+6+SW I will design a Frontpanel in inkscape and share it here ...

Is that group still active?? I searched facebook for midibox but could not find that group ....

I'm interrested ...

PCB's are all here, LCD too, TLV for AOUT is on it's way .. STM32F4 arrived yesterday, Mios for the Seq V4 IS UP AND RUNNING

Woooooowwww ....Buildmaster .. Sieht Hammer aus
