Re: DMD display, only 32 top right LEDS work

Check the four silver screws have insulated washers on the front and back of the board. You will have to remove the black panel carefully, as the plastic is quite brittle. Apart from that, I can only think that the code is set to 2 panels wide and the cables are connected properly. Cheers Dennis (ed...

Stackable, SPI controlled RGB 8x8 Led Matrix

How about a stackable RGB led matrix, that could be controlled by 3 Austria Microsystems AS1116 chips in the TQFN(4x4)-24 Package (4mm x 4mm) , or the QSOP-24 Package (6mm x 8.6mm), controlled by the SPI interface. The AS1116, controls the brightness of the display (16 levels), as well as the data i...

Inadvertantly connected 3 DMD's to 12v 5A- Fixable?

Feeling like a real idiot about now... :oops: I inadvertantly connected 3 DMD's to a 12v 5A psu. Amazingly the middle one still works.. Can the others be repaired , or are they toast? Looks like I got to go back to Jaycar and get another 2 DMD's, with a 5V 5A psu.... :( I built a psu from an old com...

Re: EtherTen with DMD - Internet Text Display

Smacks head twice I just bought another 2 DMD's and connected them up to the powerpack, and they displayed, but lost the ip again when I sent the UDP string... Then (bangs head multiple times) I inadvertently connected the 3 DMD's to a 12v 5A psu, and fritzed two of them... Now only one works, and l...

Re: EtherTen with DMD - Internet Text Display

Plugged in a power pack and voila , the ip is not being reset...to 0.0.0.0 now w...

Re: Etherten ip being reset after sending DMD data..

Some output from the serial.. Firstly with setting pin 10 LOW then run the dmd code, then set pin 10 HIGH. There was no output on the DMD at all, but the time between the ip logging was as if it was outputting the marquee.. Serial output ********************************************** 10.1.1.11 retur...

Re: EtherTen with DMD - Internet Text Display

I changed the ip for my network....and the max UDP buffer to 256 again I found that the etherten would lose the ip number after sending data over ...
