HELP WITH MAKING A- MIDI Monitor -WITH 8 digit LED display

[jason_il]

Hi all,

My name is Jason and i want to build a MIDI Monitor with 8 digit LED display that shows MIDI-Time-Code (or songposition). Now I am dont know anything about electronics and i dont follow techno this and thas so..can any one tell me wich modules i need  to build so i can get midi time cod to display ?

ALL I WANT TO DO IS to be able to connect my DINN5 conector form my sequencer to an LED MTC DISPLAY.

(I'm not going to acutally build this myself - im going to pass it on to a fraind who knows how to,

but he also got dazzeled by the amount of info on the site so he toled me - "jason, just tell me what parts you need and ill get it made for you!!!")

so please , can anyone just tell me what i need??

Hi Jason,

That timecode display is my favorite of the MIDIBox circuits. You just need the MIDIMon from www.ucapps.de with the MTC LED display. You can run it without the LCD connected for what you're doing. You'll need the MBHP "Core" module for the guts with a programmed MIOS PIC chip (or a PIC with the MIDIMon app already on it). You need seven segment displays with common anode LED's for the display. You can go with whatever configuration is convenient, as long as they have separate cathode pins for the segments and you have eight digits total (I use four dual digits). I don't think there's a board for that, but the schematic PDF is on the website. I've built a couple with the three HC595 shift registers onboard, but I guess standard procedure is to use the MBHP D.OUT module for that part.

If you, or he, needs any help with the display half, let me know.

Hey George ,

thanks for your helpfull reply.

just a few Q's in hope for sum A's....

1.You wrote: "with a programmed MIOS PIC chip (or a PIC with the MIDIMon app already on it).:

  where can i get a programmed MIOS PIC?? im sure that would save me lots of effort...:-)

2. I didnt understand this part of your repy at all: "I've built a couple with the three HC595 shift registers onboard, but I guess standard procedure is to use the MBHP D.OUT module for that part."

whats a HC595 ??? AND WHATS A MBHP D.OUT ????

I cant thank you enoph.... your reply just reminds people like me that there are nice people out there who will giv a hand to strangers..

Thanks my fraind,

Jason

Hi,

MBHP DOUT is a module that plugs to core and is connected to the 7segment displays. http://www.ucapps.de/mbhp_dout.html.. I don't know what Jidis did, but anyway something that's compatible with DOUTs. ;)

You can get programmed PICs from both "midibox shops":

SmashTV's (located in U.S.A.): http://www.avishowtech.com/mbhp/buy.html

Joergs (located in Germany): http://www.mikes-elektronikseite.de/shop_englisch/index.htm

Bye, Moebius

Hey Moebius!

It was the same connections from the schematics, just on a board with the LED's. I think I went by the mtc_extension.pdf schematic. The clock display only needs 3 595 chips (one for the 8 anodes, one for the left 4 cathodes, and one for the right). I've got them on a board with the digits and the 16 220 ohm resistors. It's got a five pin connector carrying the supply, the ground, and the three lines to the 595 chain. You're looking at 24 lines to the LED circuit for this thing, so I figure it's about as easy to put them all together and just have the five lines going to that.
