Hi,
I have a problem with my new 16x32 matrix : once i had plugged the cables into my arduino uno and uploaded the sketch on it, my matrix displays only two lines, and this with each example sketch form the library. I tried to remake the connections, change my arduino and my power source, but nothing changes ! What should I do ?
On the following picture, the arduino uno is running the scrolltext 16x32 example sketch.
Thanks for your replies.

Re: Problem with 16x32 RGB matrix
That looks very much like a wiring problem. Check your wiring again. Make sure that you have correctly identified Pin 1, and have all the connections right.

Re: Problem with 16x32 RGB matrix
Most likely it's the address pins (A0, A1, etc.)...if you can get a clear photo of the wiring on both the Arduino and the IDC plug, we can look it over for any gremlins.

Re: Problem with 16x32 RGB matrix
Here are pictures of the two sides of the IDC, of the arduino wiring and a global view (i dont know if it can help).
Thank you so much for helping me to solve my problem !

Re: Problem with 16x32 RGB matrix
Here is the last picture. Pin A is connected to A0, pin B is connected to A1 and pin C is connected to A2.
