I'm trying to set up a rather large RGB LED display. In specific,
approximately 1000 RGB LED's in a way where I have individual control of ea.
LED (color must have, brightness nice to have).
My current plan (though I need to see if this will work, no previous
experience) is to use a MAXIM MAX7219 serial in/out 8 digit, 8 segment
driver to multiplex 64 LED's for a single color. So, for RGB each panel of
64 LED's will have 3 MAX7219 chips to drive R, G, B separately across the
entire set.
The MAX7219 can be put in series up to 16 so, i'll end up with muliple sets
of 16 to control all 1000 led's.
My question is this, what other methods / ideas do people have to do this.
I just ordered some chips/led's to do some experiementation as i'm not sure
I can PWM the LED's enough to get different shades. One additional note,
I can't use an intergrated LED display as I want the ability to move/space
out the LED's in a custom physical arrangement (e.g. space them out every
1-6 inches).
Any ideas appreciated....
