:smile: Hello to all! I've built a singlecore MB SID PIC:18f452,I've checked all connections and voltages, seems is all ok. I'm having weird characters on the display while turning on and while pressing the buttons. Cuold it be a bad programming error? Please watch the video and comment. Thanks a lot guys! :yes: PS The test tone program works, but it makes a very quiet tone, is it ok? Gord The Rogue

Update. Yes that's the best solution, i went on with that and now i'm happy to have a working circuit. Thanks PS Commodore's PSU are going to be expensive and i've read around too much post about "old PSU failure" so i'm thinking about building a new one, just in case...

For everybody that come to this post, an update: I've tried the Willem PCB5.0 with the ICSP connection to the 18F452 with a breadboard and some resistors like described here http://www.tinet.cat/~sag/pic452.htm. It seems that the Willem application can listen to the PIC without the identification, i've tried to burn a PIC without goal. Thereafter i decided to etch the PicBurner module and i used that to burn some PICs without problems, so my suggestion is to use the PicBurner. Regards. Gord The Rogue

Thanks a lot guys! Yes the problem was that stupid ground connection to R12! You were right Janis1279, thank you. Now everything works, i've uploaded the MIOS and i've done/listened to the TestTone application. But my LCD doesn't work, don't know why because i've checked the connections and all is fine. It turns on, with the B/L on but no strings appear on it, neither the copyright and "ready" strings. Weird. Atm i'm doing a search into the forum, my LCD is this one:http://www.unitech-lcd-modules.com/pdf/Uc-202a.pdf KS0066 compatible. Gord The Rogue -------------------------------------------- Update: It was a contrast fault,i tuned the trimpot and now i can see something on the LCD, with something i mean black bricks on half screen (right side), no strings (no copyright logo). The visual is like this: blank --------------------------- 5x2 pix (columns X rows) brick blank --------------------------- 5x2 pix blank --------------------------- 5x2 pix blank [][][][][][][][][][][][] 5x7 pix full black bricks twelve columns Need some more testing, maybe i must check the .hex configuration; my LCD is 20x2.

Great reply thanks a lot!! I will past my sunday on this and i'll update this post, again thank you analogue_mo! Gord The Rogue

Hello to all. First of all i would like to tell the moderators that if needed they can "cut&paste" this post into the previuos PicBurner related post. My story started with failure on programming the bootloader with a Willem PCB5.0 burner. Thereafter i decided to build the PICBurner module, i had all the components so i etched the PCB without the ground copper layer because i didn't found it into the PCB Eagle's file (surelly my fault). I soldered all the stuff, grounding with cables. There's only a difference from the original, i used TO220 size for the LM317 and the 7805 voltage regulators, i checked the pinout on the Web all seems fine. The first test was bad, i burned a 74HC14 (wrong orientation), but the voltage testing passed, i'm using a DC 15v supply. I tried with other 74HC14 but: 1) Power's Green LED went on (OK) 2) Vdd's Yellow LED went on when LPT printer port is connected to the PICBurner (BAD) (LPT pins are right) 3) P18 did not see the PICburner but LPT port test (100k resistor) passed (BAD) So i checked the schematic and the PCB board, i forgot two ground pins, the R12 and the 7pin of the 74HC14. After soldering, i tested again and: 1) Power's Green LED stays OFF (BAD) 2) 7805 voltage regulator goes really really hot! (BAD) How could it possible that the 7805 goes so hot after putting the ground at those pins? Again sorry for my bad english, ask if you need more info. Thanks to all, you out there are very kind! Gord The Rogue

Thanks, i tried with the external psu (both AC and DC at 12v) but it didn't work. Also tWP=30 cannot be assigned to the Original Willem Eprom PCB5.0 Ver. 0.98D8 software, maximum is 13.0mS. If someone could help me on testing the voltage while the Pic is programmed... I dunno where to put the Voltmeter probes.

Hello to all. Today i spent the entire day on programming the PIC18f452. Nothing worked! :( ??? This is what i have and what i did. Hardware: Pentium4 2.40ghz - 992RAM (plus the videoRam on board) with Windows Server 2003® A short Parallel cable on LPT1 port with ECP/EPP enabled Programmer: Willem PCB5.0 (powered by USB) PIC: 18f452 (For a MIDIbox SID single core) Tried 4 different Pics Software: Original Willem Eprom PCB5.0 Ver. 0.98D8 IC-PROG 1.06b either with and without the icprog.sys driver WinPIC compiled in August 2008 WinPic800 ver 3.64 With all of these applications i can read/erase the Pic, but i cannot program. The standar error is at the 000000h address. Tried all kind of delay settings, also i used the API (but i think they go on only with USB). WinPic800 says: ERROR-> Writing address 0x000000 Written: 0xEF06 Read: 0x0000 Willem Eprom PCB5.0 Ver. 0.98D8 says: ERROR Program memory at 0x000000 Below you can read the WinPic log I've read others treads about 000000h error but i really didn't find anything useful or maybe i didn't understand, i need help on testing the mclr voltage, i don't know how to do it. I mean that i don't know where to put the Ground probe of the Voltmeter. Also what other stuff i must check? On the Willem Eprom PCB5.0 Ver. 0.98D8 there are two weird settings: tWP (uS value) and tWC (mS value). Don't know what they mean. Thanks to all,I hope you could help me.

:) Hello to all, I know there are around in this forum other requests like mine, but before burning something I think is better to have clear ideas. I'm tring to buy everything from a single shop so maybe I could suggest it to italian users. I would like to know if this bridge rectifier is compatible to B40C800: W04 1.5A 400V For the specs http://uk.farnell.com/fairchild-semiconductor/w04g/bridge-rectifier-1-5a-400v/dp/1017877 Thanks to all!

Thanks, now is more clear. I was wondering if i can power directly the SID module with my supply (16v) and then chain the 12v, output of the 7812 on the SID, to the power input of the Core module. Would it work? Again thanks, Gord

??? Uhm ok but the SID Module takes the power from the Core Module as you can see from this page http://www.ucapps.de/index.html?page=mbhp_core_old.html... What should i do?

Thanks for the quick reply. I'm using that voltage because i've read on the old version pages that for the CORE+SID module combination 15v is needed. The fact is that when LCD is disconnected the 7805 and the bridge rectifier don't get hot. Again thanks, i will re-re-recheck the LCD wiring but i'm sure is all ok. Gord - I forgot to write the LCD model: UC202A by UNITECH is a 20x2 http://www.unitech-lcd-modules.com/pdf/Uc-202a.pdf

Hello to all. I've started a Midibox SID for a friend of mine, he gave me the Core and SID modules signed on the PCB as V2 version (2002 date). I follow the steps on the old pages for the old version and after soldering and wiring i started to test the Core module. I checked the voltage levels as written here http://www.ucapps.de/mbhp_core_old.html and I have: IC1:MCLR(1) - IC1:Vss(12) = 4.53V <--I'm worried about this IC1:Vdd(11) - IC1:Vss(12) = 4.93V IC1:Vdd(32) - IC1:Vss(31) = 4.94V IC2(8 ) - IC2:(5) = 4.98V Could be a problem the first line check? Also, I noticed that when I connect the LCD cable to the display (no ICs on Core) this one it powers up (green backlight goes on) but on the Core module the bridge rectifier and the 7805 become very very very hot and i need to disconnect the LCD cause I fear to burn some components. I'm using a PSU with an output of 16.34V and 500mA. I'm not so sure about the mA, how could i make a measure of it? Thanks in advance, best regards to all of you guys! Gord The Rogue

I never told about 78L05, i'm talking about R1 not R2. Btw i will try with Eagle, thx

:) Hello to all As i'm building a Midibox SID i'm getting troubles assembling the Pic Burner on a predrilled board. Following the schematic from http://www.ucapps.de/mbhp/mbhp_burner.pdf we can see that: Resistor R1 (220ohm) is connected to the OUTPUT pin of LM317, then is connected to the trimpot P1 (2.2k). The central pin of P1 is connected to ADJUST pin of LM317. My answer is: why this doesn't happen on PCB's Burner layout? http://ucapps.de/mbhp/mbhp_burner_v1.gif On it we can see that resistor R1 goes to Ground and not to P1. In that way only one copper track goes to P1 central pin from ADJUST LM317's pin, and nothing comes from the resistor R1. Let me know so i can go on :-). Gord the Rogue

Salve, per il secondo problema: Io ho ordinato da Mike e ho pagato tramite bonifico bancario, perchè se non ricordo male non accetta Paypal. Cmq sono convinto che se gli rispedisci l'email ti risponde subito, con me è stato disponibilissimo. Per LCD, proverò a dare un'occhiata al pinout,ma dimmi precisamente quali segnali(nomi) non ritrovi nello schema LCD di ucapps.de?? Gord The Rogue

:D Thanks for the quick answer!! Talking about last DINx4, i understood to don't stuff 3 shift registers but: 1)Have I to stuff one shift register and near R1 to R8 resistors, included R33 right? 2)What about others resistors (R9 to R32)? Do i have to stuff them? Also R34 to R36? Thank you again :-) Gord the Rogue

:) Hello to all, Finally i'm starting to build my MIDIbox SID Control Surface ver. I'm getting troubles on understanding the DIN soldering and wiring work. On DIN pagehttp://ucapps.de/mbhp_din.html we could read on 'Used Components' chapter that: (talking about the 10k resistors).Does it mean i don't have to put resistors where i'll connect the encoders on DINx4 boards? Into the connection diagram http://ucapps.de/midibox_sid_cs/mbsid_din_default.pdf i couldn't see where resistors are and where aren't... instead of http://ucapps.de/midibox_sid_cs/mbsid_dout_default.pdf diagram which has resistors drawned. Again on http://ucapps.de/midibox_sid_cs/mbsid_din_default.pdf: the last board on right side is a DIN, does it have only one 74HC165 shift register? ??? If so, what i have to do with the others three 74HC165s banks? (i have only DINx4 boards) I must put bridges or resistors(which?) between each last 3 shift registers' pinouts? ??? Just a comment: on diagrams .pdfs couldn't be usefull a legend that clarify which symbols mean buttons, which mean encoders, etc.?? I hope to be understandable :-) Thanks all of you ppl out there Gord The Rogue

Thanx!!!! about contact resistance as you can read on that link "Contact Resistance: 10m&#8486; max. typical @ 2-4 VDC, 100mA" What about Tactile Pushbuttons?? I've a lot of them desoldered from old TVs and other electric stuff... ;)

:) Hello to all, Which kind of specs must have pushbuttons for MIDIBox64?? I'm talking about two main things: - The ON-OFF states - Electric specs like contact resistance and so on I've found this button http://www.e-switch.com/pdf/Series5500Pushbutton.pdf maybe someone knows this mark or can say to me if they are right for MIDIBox. Thanx, these info are very needed cause i'm going to order and i don't want to buy useless things.

;) Salve a tutti (per quei 4 gatti che leggono) Non riesco bene a trovare il tipo di caratteristiche che devono avere i pulsanti da utilizzare sulla MIDIBox.... Voi cosa suggerite? meglio i push buttons o i tattili? Grazie

;) Hello and happy new year, i've find this LCDisplay from a friend and i wuold like to know if it could be driven by MIOS system. Specifications: (for datasheet just google) Manufacturer p/n: Vikay VK5121ELYG Module dimensions: 84 x 44mm Display dimensions: 62 x 24mm - 120x32 pixel Controller IC: SED1520F Backlight: Electroluminescent i found this helpfull link (hope) http://users.skynet.be/bk317494/013/013.htm ???Also, which kind of specs i have to know when looking around for LCDisplays for my 64?? ??? i'm talking about LCD controllers not mentioned in LCD section in ucapps' site. As i read: "Since MIOS V1.3 it is possible to integrate a custom LCD driver into the application." Thx mates for help. Gord The Rogue

:) Thx Roger. Why 10K?? And which kind of pots do you suggest? What about 'quality'? With coal film, Cermet, plastic?? This could be an interesting and helpfull discussion so come on ppl suggestions/experiences are welcome!! 8)

???Which kind of potentiometers do you suggest for a MIDIBox(64/128 ) ??? I'm starting learning electronic and i don't have clear ideas; in which way i can "calculate" the necessary resistance of my pots into the circuit? There are formulas that i can understand which explain how to define potentiometers needed for the AIN module? This comes cause i'm going to buy pots but i don't know which resistence they must have to "best fit" on AIN Module. I try a search for this question on the forum but seems all here are geniuos ;D Btw forum/site is very good!!! and full of info but i think they take for granted little stupid questions like mine... Don't take offence, i need your help now and in the future. ;) Gord The Rogue

:D Salve, che tipo di potenziometri bisogna utilizzare per il MIDIbox? O meglio, che tipo di 'percorso' bisogna fare per scegliere i potenziometri? calcolare le impedenze dei potenziometri a seconda dell'amperaggio dei vari moduli che si useranno (leggi Core, AIN, DIN etc..) ?? andare a caso? :o Inzomma suggerite suggerite, scrivete le vostre esperienze altrimenti gli impediti come me nn sapranno mai da dove cominciare :P Gord The Rogue
