Need someone to test PWM matrix LED project

Bean

I'm making a SX28 program that will drive an 8x8 LED matrix with PWM.
In other words each LED can have a different brightness.
I don't have an 8x8 LED matrix...And I don't have the time to build one.

If someone would like to test the program please let me know.
You will need: SX28 chip, SX-Key, 8x8 LED Matrix, 8 NPN transistors (for column driver)
The program will accept data at 9600 baud, so you will need a BS2 or some other means of sending the data.

If I don't get any takers, I guess I'll have to order one...
Bean.


EDIT:

· I have attached the program. It receives data at 9600 baud inverted. You send a header of "!PWM" then 64 bytes of PWM values, (Column0:Row0), (Column0:Row1),().().(),(Column0:Row7), (Column1:Row0) etc..

Any questions please ask.

Let me know how/if it works.

Bean.

I'm in the CA office and can probably adapt the code to work on one of our Robolympics badges.

Terry,

I've got a pile of 5x7 on order, but they're not in my possession yet....I suppose this doesn't really help.· [noparse]:)[/noparse]

Jon, I thought you were in TX, did you move or are you visiting the CA office?

I have attached the program to the original post above.

For the next few months I still live in Big D (Dallas) and visit the office every eight weeks or so -- much easier to "stir the pot" in person. · At the end of the year I will return to my Los Angeles area roots.

While in the office·I'm working with my colleague, John Barrowman, on EFX (see www.parallaxefx.com)·proejcts.· In fact, we just used SX/B to create a serial inteface for a cool little relay control board.· We are interested in a LED dimmer, hence I'm going to look at (and perhaps "liberate" portions of) Terry's code.
