Programming LED graphics
May 21st, 2005, 7:43pm
 
HI
I am wanting to display graphics on an LED board. But I seem to be going round in circles. I've looked at Basic Stamp and am very close to purchasing one. I've also looked at, and quite like, though they are pricey, the B64CDM range from Nexus
http://www.nexusmachines.com/Products/pdf/bifqdata1.pdf
which have chips built into them.

so my question is this:
can i use processing to interact directly with the LED matrix if i have control over the serial port, via a controller of some kind. or do i need to use something else, like assembler, C etc. or if i use Basic Stamp, then their Basic language.

And if there is a way to use processing (using Wiring??) do i still need to address each pixel/LED seperately, or is there a way of animating them by some sort of screendump. I've been experimenting with taking a series of gifs, then converting them to a binary series of 1s and 0s. but surely there must be a more efficient way to animate.

do i rather build my own boards, using a LED 8x8 matrix and  max7219 chips, which seems pretty scary. It seems like using the Nexxus B64CDM in conjunction with the Wiring Board (if i can get my hands on one) would be ideal. The B64CDMs can link up, would this mean i'm only using 3 pins on the wiring board?

or how would i go about this? what's the simplest and most cost-effective solution. ideally i would want my LED matrixes (i need to build 5) to be 64x32.

i'm stuck bigtime.

any help would be greatly appreciated
thanx



Btw. if you hadn't guessed yet my electronics knowledge is pretty shoddy to say the least.

yes, i have. i will post the code soonish, once i've ironed out the last few issues.

You should check out this:

His development blog shows you how to make it, looks like he used Processing for parts

looks good, need to get better at electronics though Wink have asked him how you would go about doing it using a wiring board rather than stamp.

thanks for links, very inspiring Smiley
