I split your post off into a new thread because it wasn't related to the thread you posted in.

I can't see any reason why your program doesn't work, sorry. Maybe it's a problem with the keypad wiring?

No, the library only supports WS2801 at this stage.

Hi Synaesthesia, I haven't experimented with video files. I think on an 8-bit AVR based Arduino this would be a stretch, even the "flames" example - just loading BMP frames - is really stretching it. The Arduino EtherDue is our Freetronics Due-compatible 32-bit product. It has a lot more grunt for t...

Hi Synaesthesia,

Thanks for posting the pics. It looks to me like the white & yellow leads might be connected to digital pins 50 & 51 instead of 51 & 52 (the bottom pair of pins is GND, the row above is 52 & 53, and the row above that is 50 & 51.) Can you please check and confirm?

Hi xtoph, Thanks for posting the datasheet. I can't see any problems with the wiring, although the video looks to me a lot like it could be a coil wiring problem. If you use a multimeter in Resistance to measure each coil (blue to red, then green to black), do you see resistance in each pair? What h...

Hi Synaesthesia, Thanks for the update. You don't need to change anything in your code to change power sources, just move the jumper on the board. The microcontroller runs at 5V in both cases, it just gets the 5V via a different path. Is it possible for you to post a photo of the wiring configuratio...

Hi,

Freetronics DMDs are not marketed as "P10". They come in Freetronics packaging with a "DMDCon" connector in the box.

You can view our range of DMD displays here: http://www.freetronics.com.au/collections/display/dmd

Hi Synaethesia, Sorry to hear it's not quite working correctly. Moving to the internal MicroSD slot is a good idea. The EtherMega uses digital pin 4 as the MicroSD "CS" pin - which is already the same pin number used in the example sketches, so you shouldn't need to change anything - just move the c...

You can try removing the "lcd.clear()" line (which will erase the entire display each time it redraws), although you might find you need to print some extra spaces ' ' so it doesn't leave "cruft" at the end of the line when it draws the new time over the old time. At the same time, you could also tr...

Hi Chris, Sorry to hear it's not quite working yet. At the moment the code updates the time, then waits one second, then updates the temperature, then waits one second before updating the time again. You can try updating both at the same time. Change this part: void loop() { displayTime(); // displa...
