Topic: Building and programming a 8x8x5 (Read 4561 times) previous topic - next topic

Something along the lines of this http://www.instructables.com/image/F9M4NEJGTUG0WPI/Creating-the-LED-matrix-2-of-2.jpg
Using this http://www.maxim-ic.com/images/qv/1339.gif to control the 5 separate 8x8 blocks

So what I'm wondering is... how do i go about this, I;m super super new at this and have NO idea what I'm doing?

1) What wires to go where?
2) How do i then go about programming? i want to achieve something like this, having it controllable and able to choose individual images with a remote and such would be great

Thanks for any help, im sure its been asked a bunch but i cant seem to find it anywhere. this would help me out a ton

Do some reading at this thread which has links to a 56x8 display, 40x8 would be similar.

The concept is good, but the way it runs would be too large to fit into a helmet.
thats why i thought using the MAX7221 would work to size it down.. would that component not work?

This is the custom board the guy who made the Visor worked.. if there was a way to get this manufactured it would also make it easier

(Know of a way to get that built for me?)
But i would still need instruction on the arduino part of it

MAX7221 only drives 1 8x8 register. You looking to use 5 of them? That would make the design a lot simpler.
Can do 5 boards like that, appears to  be setup to daisy chain them.
Then as you say, the coding becomes the key to the display.

Some cleanup needed, labels, but this is  basically it.

This is the board he used, do you think you could reproduce it into a Gerber File so i can get them made?

unless its the same as the board you made, in which case could you label it and give me a Gerber file of it for production?
That would be super awesome, cheers for all the help mate

I made the same, just looks a little different.  Will get to labels/gerbers in a few days, working several other things right now.
Maybe get someone else to finish it up.

im getting "the file (max_breakout7221.sch) is not a valid EagleExpress File.. am i doing something wrong here?

EDIT: tried opening with Allegro, its telling me the files are corrupted. can we try this again? Thanks!

im currently using Eagle 6.1
EDIT: ther it goes, after a re-install its all up and running.. CHEERS! this is exactly what i need! i love you
EDIT EDIT: Alright now ive got the board, if i go to print it at say BatchPCB.. will it come with the resistors on it or is it my duty to solder those on?

Octobarian

Could you also explain where to wire the Arduino(yellowjacket) up to? im guessing its the DIN, CLK and CS?
sorry i know its alot of question but this is my first attempt at something like this

CrossRoads

I've not used batchpcb. I expect they only make bare PCBs tho, assembly is up to you.
Signals: MOSI to DIN, SCK to CLK and D10 to CS, and GND.

This is the board i plan on using, i cant see the connections on it (its a re-interpritation of the yellowjacket)

Which ones do i connect what to?

CrossRoads

D13 is SCK
D11 is MOSI
D10 is CS
Gnd is Gnd

Awesome, okay when i print the board now.. will it come with the MAX7221 on it? or am i going to have to find and sodder that on? where would i get one of those?
Sorry, i know im new at this...
