- When I remove the usb my display garbles.  Video of error http://bit.ly/HF9DxV

I am experiencing this problem regardless of usb in or out.

Ive tried with a Arduino Uno Rev3, and Arduino Nano 3.0.

using the code from http://code.google.com/p/ht1632c/source/browse/

It seems like the upper left segment of the display to the right is a copy of lower right segment of the display to the left

Code: [Select]
so if this is a working display:
aabb1122
ccdd3344

then mine is like this:
aabbdd11
ccdd2233


images of the display running example sketches: geometry, line, fill and cirles:


any advice?

Can you post the code you're using for one of those examples?


Im running the examples without modification, Ive matched the pins and use the same on my Arduino Nano
http://code.google.com/p/ht1632c/source/browse/examples/geometry/geometry.pde
http://code.google.com/p/ht1632c/source/browse/examples/line/line.pde
http://code.google.com/p/ht1632c/source/browse/examples/fill/fill.pde
http://code.google.com/p/ht1632c/source/browse/examples/circles/circles.pde

Im pretty sure ive done it before with the same results, when this first happened I thought maybe one of the displays was broken, but I remember they show the same result in both configurations.
Will test to swap the displays and post results in a couple of hours.

Swap the displays. Do you get the same thing?


Doh, they worked as expected when I swapped them, which make me remember that I only tested them individually before and not chanined in this way.

when swapping back they still show the problem, is this common? they aught to be the exact same panel and thus the result should be the same regardless of position.

Have you seen this before?
