I think on Axel's 'über-midibox' (plain awesome, really!) he used the Midimon thing (PIC16F877)http://www.ucapps.de/midimon_en.html The hardware connection on the DXOUT is the same in MIOS apps, but the software needs some altering, especially for the kind of displays I wanna use (if it is even possible) The final intention is to have a bunch of encoders with their corresponding value shown on a display (1 per enc) instead of LEDrings. I got more or less an idea of how it all shud work for the user (with channel & CC number settings etc) but I need to dig deep into MIOS & ASM .. I hope I dont encounter a 'balrog' on the way down :D greetz

Like I said, I'm going to *attempt*... ;) First I kinda need to learn by heart the PIC's & SR's datasheets, assembler and the MIOS instructions, then I need to decypher the examples & then... then... then it is probably xmas 2008 or so 8) btw, the 2-1/2 displays I'm using are on Ebay starting at 1Euro for 16 pieces, the seller must hav loads of these I think. greetz

Besides the talkingelectronics site (I think I got the subscription for free when I ordered some stuff there) These may also be of interest: www.piclist.com ofcourse http://www.matrixmultimedia.co.uk/picmicro/picprods_1.htm#elpc I have this cdrom (home/student license), pretty OK for the basic stuff. http://www.godevtool.com/ WIN assembler stuff, but has some tutorials that may help to understand the principles. greetz

on www.olimex.com (Bulgarian PCB service & stuff co) there is a list with more tools, direct link: http://www.olimex.com/pcb/dtools.html greetz

It is called C.O.D. (cash on delivery), this comes with an extra cost (to pay the postman for the risk returning with his pocket full of $$$). However, a bank transfer (banküberweisung,vorauskasse) should be without extra cost inside the EC.(since July 1, 2003) Ask for IBAN (International Banking Account Number) & BIC (Bank Identifier Code) numbers. greetz

the pathname is too long, move your project files to something short like c:\projects\ for example, that should help. goodluck

Okay, for those interested, I smashed together some hardware prototype to start experimenting with LED displays. From here I will attempt to modify the sw to get it running. (if ever...) For now you can take a look at some pics of the proto hw: http://www.angeltowns.com/members/driftz/ site can be a bit slowish tho... comments will follow later. Tips & comments welcomed ofcourse ;) best regardz, DriftZ

OK, thanks for clearing this up :) I'll do some experimenting for sure but I was thinking about using 2-1/2digit LEDdisplays, they have a multiplexed connection (5+4wires) & I just wanted to know before I start building some hardware that perhaps would possibly never work with MIOS. MFG DriftZ

Hello, I still am struggling with certain aspects  :-/ http://www.ucapps.de/mios/leddigits_16.pdf On this schematic, we have 1 DOUT module with 4 shift registers; could we call the black lines 'scanlines'  and the green & blue lines 'datalines' ? Then my question is, *must* the scanlines & datalines be on different shiftregisters ? (like it is done here) or would it be possible to have like e.g. 5 datalines & already 3 scanlines on the 1st shiftregister(SR) ? Then 5 scanlines & 3 datalines on the second SR; 2 datalines & 6 scanlines on the 3rd SR etc... Thanks again

I'm also ready to become a 'donor' ::)

errr... i'm trying to understand it, meanwhile: 3^2=9 (ofcourse) & 2^3=8 ! i'm trying to pour these theories into schematics atm, we'll see if it makes sense to me 8)

I have been thinking about this, but... these are BCD-2-7seg decoders, so actually they only would reduce the number of common lines, right ? like instead of 8linesx8digits one would get 4linesx8digits+4linesx8digits ? But would a 3 to 8 decoder (3^2=8 ) also work then ? or has it got to be a 'driver' IC ? (plz forgive my lack of knowledge of electronics terminology) best regards

Cool, thanks for clearing this up, Mr. TK! I'll have to study MIOS a bit then. :) Not sure howto use extra hardware tho, but I think the basics (1 core & some DOUTs) should be adequate. cheers

Ok, so according to: http://www.ucapps.de/mios_download.html http://www.ucapps.de/mios/leddigits_16.pdf The MIOS intro says: http://www.ucapps.de/mios.html Hmm.... 64 is near unlimited ? :D I see that on the schematic that the digits are split in 2 groups of 8, each sharing the 8 wires... Could it be made to have 3 groups of 8 digits ? Does it have to be common anode displays, is this required by the software or the hardware ? Thanks for more light on this :)

DriftZ: go read the download section at www.ucapps.de duh 8)

hmm, just thinking.. Under MIOS: Is it possible to use 7segment displays (3digit, 0-127) together with encoders instead of Ledrings? howmany of these could be used then with 1 DOUTX4? (7common wires for all digits + 1 per digit? makes..... 32-7=25... so 8 times 3digits, correct ?) & if it is possible, howmany per core ? thanks for any info on this :)

this looks awesome ! must have :) ;) :D

I was having some problems But I just figured it out I think. For ppl using the EPIC programmer: Make sure to check 'program/verify ID' in the Options menu. Symptoms: bootstrap not sending sysex but pitchbends & reset msg's. after checking the ID setting: bootstrap sending sysex F0 00 00 7E 40 00 01 F7 I think it should work now (I guess.. I hope.. I pray... ) My LCD now displays 'READY' :D :D :D DriftZ

Hoi, De Alps zijn kwaliteits producten. In België is het ook moeilijk om zulke dingen te vinden, maar.. www.albs.de is de verdeler van Alps in Duitsland. http://www.alps-europe.com/index.php?PHPSESSID=f16045d903327a833843a81522f52392&mapid=18&PHPSESSID=f16045d903327a833843a81522f52392 Spullen uit de europese catalogus (euro selection 2003 ; 11mb pdf) halen ze van de plank, andere dingen moeten van Japan of godweetwaar laten overkomen (+$) Als jullie gezamelijk bestellen (minimumaantal =100) dan vallen de prijzen best mee. Minder dan 50% van de prijzen van RS in ieder geval. Online bestellen of via email, stuurt je een proforma factuur. Levert vrij vlug. Opgelet: vanaf 01 juli '03 zijn overschrijvingen binnen EC gratis!! Hij heeft ook nog de STEC16B encoder die TK gebruikt heeft (wordt eigenlijk niet meer gemaakt, staat ook niet meer in de catalogus 03, wel in de vroegere) Eventueel kunnen jullie ook hier eens proberen: http://www.dst-gmbh.de Hoop hiermede jullie van dienst geweest te zijn. Groetjes, DriftZ
