Sure Electronics 64x32 LED Matrix...

Bamse

Here is the start of a Propeller driver for the LED matrix from Sure Electronics.

This was a little bit tricky to get working since the data sheet is not the best...
However after reading the thread for the SX48 driver I managed to make sense of the whole thing...
The Matrix have been bit mapped for easy use and the driver runs in a separate cog...

Nice! I have always wanted to get a nice large matrix and toy with it. How much does it cost?

I am 1011, so be surprised!

About $50 including shipping if you order from their web-site...

However the SX thread suggest that you can get it cheaper from E-bay...

My display had one dead Green LED though, if you look closely at the R in GREEN you might be able to spot it...

I'm glad to see the work put in by PJ Allen and myself is being expanded on. Be sure to look in Nuts and Volts magazine in the next few months for an article I wrote about the display and applications (as explained in the link below).

BTW: Here is the link to the SX48 / 28 versions that·Bamse mentioned: http://forums.parallax.com/showthread.php?p=746212

You can get them on Ebay for about $58 with free shipping: http://cgi.ebay.com/6432-Dot-Matrix-3mm-Bicolor-LED-Info-Board-Demo-Board_W0QQitemZ250305636655QQihZ015QQcategoryZ26206QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

or at the Sure Electronics site for $37 + $21 shipping from China. I have ordered many of them and they have great products!

I paid $35.99 for the board and $13.71 for shipping...
Totally $49.70...

I decided not to get the demo board, maybe that saved me on the shipping...

How about big numbers and smooth scrolling...

Cool! But do not get too far! I want to have something to work on!

Well, so far I'm just playing around...

I want to make a PONG game...

I got the MCP3008 hooked up and the Commodore Paddles connected...
However it looks like the pots in the paddles are logarithmic so I need to figure out how to convert it to a linear scale...

I basically need to convert a logarithmic value of 0-1024 to a linear value between 0-1024 using Spin and integer.
But that is something I'll look into tomorrow...

Hmm, what about two boards...



Still just goofing around...

I have been able to cascade (2) 6432 displays together thanks to PJ Allens work - on an SX28 chip. However, the routine required moving from a 20 MHz resonator to a 50 MHz resonator due to the scanning routine used most likely.

That is Sweet, I like your font, a lot cleaner than the C=64 font I'm using....

By the way, I updated my previous post and added the code...
It was late, sorry I forgot to attach the code...

Take a look at this link: http://forums.parallax.com/showthread.php/148742-Sure-Electronics-6432-board-equivalent-by-Embedded-Adventures-in-UK?p=1191936#post1191936

This looks like an equivalent to the Sure Electronics 6432 obsolete board with some very minor changes.

Here is a video of three 16 x 32 boards. I treated the display as a dumb frame buffer, 96 x 16 x 2 = 3072 bits. I just re-write the entire thing each time I put up a new column. I used machine language in a dedicated cog.
