a normal din and dout do work as they should (allthough i havent checked every key.. the col3 problem was solved..)

i inadvertantly found out why my din didnt work.. i had the ICz in backwards.. dumb old me..

ive tested another keyboard.. this was doing the same thing.. ive checked the resistance between col:3 and col:1 on the keyboard itself.. no short.. i think im gonna try to connect a normal din and dout and see if the problem remains..

well.. ive been a bit stupid.. didnt try out the test programs that TK had made.. the scan matrix examples.. they work.. and they uncovered a problem!! appearantly my col:3 doesnt send anything out.. instead it says its col:1 ive tested the the circuit ive made which bill put together.. but the resistance between the col:3 pin and the col:1 pin is about 20kohm.. which it should be.. as all the other pins have the same resistance between them.. ive replaced the shift register.. which didnt seem to help.. so now ive got this weird problem.. as only this col doesnt work and all the other work..

felicitiert?

how are you coming with the program?

i could only order a4 and a3.. also the stuff is not very cheap so i would want to use up most of the space for different things instead of covering my frontpanel with clear lazertran

what i was wondering with this stuff.. if you spray it with solvent laquer so it becomes clear, would you still see the lines where youve cut it out or only the image itself.. in other words how transparant does it become..

you have used them on a core? without building an inverter for the power.. then it doesnt need an inverter.. as far as i understand the datasheet.. it doesnt need that.. PM me with details for payment.. and i can give you my address..

thats about 9 euros per display.. thats not that expensive.. you know what i can take 4 displays.. then the cost for 1 display is about 7 euros.. just to be certain.. they are midibox compliant? and i dont need to invert power for it??

im dutch and ill have 2.. but i would like to know if shipping to holland isnt that expensive.. otherwise i would have to change my mind.. also i dont need to invert power for this..

checkout this topic http://www.midibox.org/forum/index.php?topic=6505.30 i am actually already trying to build a scrapyard monome, well Bill came up with the idea for using the c64 as midicontroller.. but i am researching if the monome program can be modified to accomodate for the c64 controller..

idealy i would have a 16 by 16 grid (we could beat monome to it :P) and the pcbs to go with it.. also the plates for the frame (cant we have a group order with that? let someone cnc it out for us.. in groups of 4 by 4 like the pcb and the buttons itself.. with mounting holes in every corner of that 4 by 4 plate.. we would also need a modified mios program that just turns the buttons into outgoing midi signals and convert the incoming midi signals into leds going on or off.. to do my part i am willing to build or modify some of the MAX/MSP programs monome uses (they are opensource!!) so that its a fully monome clone..

jup monome clone sparks my interest very much..

wow.. thats so cool of you.. THNX!!

if i rotate it 180 degrees its gets even more weird.. the sequencer start is on 0 then instead of run/stop as for code variations.. maybe it wasnt clear.. but im nowhere near your level yet.. edit: now im actually reading your code.. im affraid i wont learn this in a week.. :S im gonna try to write a program that just sends out a CC value for the keys and the 5 pots.. i have a lot of cewl ideas.. but if im to get ahead with my project its best i implement them in max/msp instead of the box itself.. however im gonna write up a document with the ideas.. argh.. this is taking too much time :P nah its all good.. maybe ill change my mind again..

no bankstick installed.. however it does it when it starts up.. when it has started up fine.. it runs fine.. as for the foto of my keyboard.. check this..http://hku.wisefire.net/ dont try to read it.. its dutch.. the keyboard looks the same.. it has 64 keys.. but it works prolly different.. as i get weird shit when i punch the keys..

yup.. it works.. i prolly need to open another topic on this.. i dont wanna fowl up your topic with my banter about building one.. but before that.. here are some things i found.. the screen gets gargbled sometimes with weird characters.. as if im looking at source code.. this is appearantly cuz of the way i plug in power.. weird.. only 2 of the 5 pots actually send stuff.. they all work.. as i can scroll through the "source code" with all 5 of them.. keymapping is way off.. i have used a c64 mark2 or whatever its called.. the one with the 8580.. if this program is going into the world this keymapping should be fixed.. tell me how i can help..

had to replace the PIC.. as i was getting a load of nonsens through the display.. but right now its in working order.. i really like that sequencer!! well it looks good anyway..(but ive seen the buggy problems with it.. as it cuts right through text etc.. but i dont mind..) i havent actually controlled any synths with it yet.. first i have to fix the problem with it sending out a whole lot of controller data.. (well i have to install the pots now.. that should eliminate that problem..) but so far so good.. and i like it.. however im gonna need a whole lot of changes :P

maybe there is something wrong with te fact that it says SI instead of SL on my board.. but im guessing thats just a typo from your side.. *a bit later* ok i think i have it working now..VD and VDD, VS and VSS are not the same thing.. appearantly they are exactly the opposite thing.. rotated my power plug 180 degrees did the trick.. i think..

im guessing its somewhere along the powerlines.. as ive disconnected all the wires exept the power.. ive also disconnected the power wires.. and it did start up.. however it does work without chips.. and ive replaced both chips.. edit:also ive measured resistance between vs and vd.. and with chips in place there is an infinite amount of resistance.. edit2: also if i put one of the chips in (either one) it wont startup..

http://www2.hku.nl/~ijsbrand/midiboxsid/c64/ actually when i havent got the chips in the board, the core does start..

little prob with your schematic.. what would be the problem if the core wont startup when you connect it.. and does connect when its unplugged

i have probably a different view on what i would like to use it for.. but i have some interesting ideas which could be build into the workstation.. also i think i can reduce code size.. but that is a uncalculated guess.. also id rather PM or MSN than anything else, i have a dislike for email.. my email boxes are chaos..

hey Bill, THNX!! ive glanced through it and its a bit advanced for me.. but with a bit of time.. as for questions.. i rather post them in public so everyone can benefit from my stupid mistakes.. unless you dont want your code to be used by others..(excluding me ofcourse :P )
