Hi
I hope it is right place for this topic :)
I just programmed pic18f4685 (thanks Wilba http://www.midibox.org/forum/index.php?topic=8328.msg58220#msg58220).
I have done all changes - 4bit connection for LCD, CAN bus with diodes-
uploaded new midibox_sid_v1_74685 code - but since I go to 4bit, my VFD http://www.bipom.com/documents/peripherals/vfd202.pdf
not working OK. It go to "pause" after second. Sometimes it show nothing, sometimes only small part of screen.
In 8bit everything was Ok, but I don`t know why in 4bit there are problem - since on datasheet is also 4bit mode.
Someone has the same problem?
I would like to say that on another LCD 2x40 everything work OK in this mode, but I prepare CS just for this smaller VFD!
Maybe it is the same problem like has Wilba on his PLED in 4bit mode?
Can someone help me? Any suggestion?
-
Thank you!
Of course my "problem" was stupid. I don`t know why I not read changelog.
I`m from this type of people who not read manuals, but play from beginning.
I`m too fast. But it will be change - after 40 years for egzample.
OK - it`s time to finish my panel :D

Hello can you help me?
I try finish my panel for sid, everything works great, but when I push 2 or 4 buttons from destination buttons then all leds start to blink. When I press one more time any two buttons form destinations leds back to "normal" - no blinking mode.
Is this a normal or not?
When I press 1 or 3 or 5 buttons - everything is OK.
Since I press 2 or 4 buttons at once - the leds just start blinking.
Also when it blinking, for go to normal behavior I must press 2 or 4 buttons at once - from destination list.
Sorry for my funny english, but really would like to get sure that it is normal or not.
I wrote to developer of Pikdev for adding new pices (18f4685) becouse I would check also if never SID aplicattion have the same behavior.
(Also I need be ready for SIDv.2)
Thank alot!

Thank you for this. Ok I see that it was a good choice to order this superb http://www.midibox.org/forum/index.php?topic=9132.msg64907#msg64907 capacitors.
It seem that it is a time to buy better measure tool (with ac and dc ampers, and with capacity), ahhhh .... nice one could be also have sonometer. It`s my dream: to have sonometer for checking rms level of my speakers.
OK guys - Thank you one more time (not last of course) ;)
-
I don`t wanna bother, but could somebody explain me (or put a link) why it is important to select the most the same values of filter caps?
What happens when they are different?
Please be patient for my questions.
-
Yes I see. Very simple and also can be (probubly) controlled from AOUT_LC by SID - inside patch.
I will do 2 stage delay: first one short (for modulating flangers) and second for longer delay, but first I will compare with your another great propositions at this forum :)
-
OK I see, but I found new one interesting : EXTernal menu.
If I understood right it will be posiible to save with patch settings of external voltage controlled gears!
I right now start build cheap one delay, and MBHP_AOUT_LC interfaces. Thanks x milion
-
Thank you stryd_one, revelation!
-
I don`t wanna bother you Thorsten, but is it possible to use Assign knobs on CS to
send predefined NRPN? Thankyou
-
Yes this is danger. I cannot be in obsesion.don`t let your girlfriend find outFortunately she loves SID sound too.
I would like to build delay into sid (with precise time setting+possibility equalizing feedback). Do you know any DIY project with this kind delay?
-
Wow, it is super! I will jumping :D :D
-
Thank you for fast response.
Your arguments are good for me. Ok I will try to get this 100 superb caps. For SID I can do everything.
-
Hi
Hey Thorsten can you add (or maybe it is added) one function:
possibility to set "4 Synthesizer Subsystems" by MIDI?
I mean: possibilities of switch beetwen for egzample
4x MBSID-Drum to 3xMBSID-Drum + 1xMBSID-Lead by MIDI.
Loving qbas

What a caps are you use? It`s a regular from shop or a special one for audio?
And what value for 8580?
-
Hi again
I read topics about filter caps, and I have decided to use 22n becouse some guys said that it is safe value. Also I noticed that on C64 orginally was 22n too.
So firstly I used canibalized ceramic 22n only for testing. They give me beauty sound.
Since I`m finish additional 7 sid modules I bought regular ceramic 22n, but they give me similar sound, not the same like previously. Personally I like more sound this from older one caps.
What is your proposition for me:
a)looking for another 22n
b)changing to another value (what are you propose? I looking for brighter sound since I use external filter too)
c)waiting with this new caps, becouse after some time they will play better (it is my theory)
-
I forgot thank you all people who want help me.
Big thanks
-
Altitude
you helped me enough! Everything is egzacly what I espected.
Thank you. Now I will make my step C.

hi styrd
from other side: in eagle is an option for export image, where is possible to put resolution in dpi.
Automatically resolution in pixels depend from resolution in dpi,
but I have not an program, with support fpd or dwg, to export as image with the same options, where resolution in pixels depends from resoluition in dpi.
I`m not an graphic worker, som maybe I`m in wrong, but when I created pcb from eagle
I exported in 300 dpi, and nextly I imported this files to blank document, who have 300 dpi/A4 , and print normally on A4.
If you can make me bmp, or jpg in 300 dpi - I will happy
-
In short: can you send me pdf - if you think that it is enough?
I use dwg_img program who have not pdf as output.
I hope soon this topic will be closed with positive result.

Hi
Thank you for trying help me.
I checked INKSCAPE, this is very good program, but it not read "fpd" and "dwg" format :(
I have my bmp file in hi rez - converted from dwg, but without any scale - I don`t know proper size. So I need any file (can be small size jpg in 2 colors) but with specified size.
For good understanding: I can stretch picture, but I don`t know how much.
After preparing good sized file I would like to print it on transparet plastic and drill my wood for sid. Can you help?
-
Please!
Everybody there done athe panel in Schaeffer Apparatebau?
I don`t think so.
So if you cannot give me this graphic file please explain me how you done a panel.
-
hi
I need help with creating a file or find another solution.
Becouse I cannot run under Ubuntu the Front Panel Designer program - I cannot create bmp file with picture of panel for sid (I think that in FPD it can be done). I need this panel picture on paper for help make me my own panel on wood ( I have no money for this super alu panel now).
Of course I can convert dwg on bmp file, but converter program not create file with orginal size (dependly from dpi), but always I must specify size (A4 or another) or resolution.
If I do mistake please tell me,I hope my text is clearly, or simply If somebody can send me in 300 dpi a graphic file with panel template I will be greatefull.
Thank you
-
so I only did one mistake.
1 x ufffff
-
Good question, since I thinked that it is good price.
In regular shop I seen twice bigger price. Have you better price?
If yes tell me about it please.
p.s. It seem to be better talk with peaople on our forum.
I buy one mounth ago vfd 2x20 for over 40euro, but used - some pixels aren`t bright like others.
Now I see my too fast mistake. But If you have acces to less price , then I see my mistake twice.
Life is brutal, but I love live.
Problem with vfd display in 4bit mode
in Testing/Troubleshooting
Posted
Fast and precision, in point.
Thank you Wilba. You known that I asked you for this driver, but not directly.
When I see (one minute after I post my problem) that you read this, I get relax.
OK- now I will check, I hope no more "questions" will be - only "thanks"....
.... after 3 hours tryings, of course with removed gound on D0-D3, and done all needed connections. Unfortunatelly the effect is the same.
I will try to change driver, if you give me a link for datasheet of your pled Wilba then I will compare differences - maybe it "give me some inspiration" - like said T.K oneday.
My vfd sometimes work for 3 seconds intensive with changing patches fast for egz., sometimes initialize failure.... I feel that it is possible to get it work, but I can`t find where is problem.
Also all time regular LCD work good.
