32x16 RGB LED Matrix code

[belextronix]

Hi i bought a 32x16 RGB LED Matrix now i am testing it but i can't get the code uploaded to my arduino.

I get following error in example testcolors_16x32

Code: Select all

testcolors_16x32.cpp:5:53: error: Adafruit_GFX.h: No such file or directory
In file included from testcolors_16x32.cpp:6:

Please help

I am using arduino 1.0

Hello,

There's a second Arduino library that also needs to be installed for this: https://github.com/adafruit/Adafruit-GFX-Library

I'm updating the tutorial right now. Apologies for the oversight!

Thank you for the fast reply

It works!

How can i change text speed?

I also have 4 white lines 2 on top and 2 in the middle

Howdy,

Regarding text speed: is this in the "scrolltext_16x32" sketch? As written, it's currently moving the text at full tilt, one pixel per frame. If you need something slower, easiest is just to add a short delay at the end of the loop() function, e.g.: delay(100);

If you need faster, best route would be to move it more than one pixel, e.g. change line 65 to:

Code: Select all

  if((textX -= 2) < textMin) textX = matrix.width();

As for the two white lines: I just encountered something similar today with a freshly-unwrapped RGB matrix, and it turned out to have been a problem with the ribbon cable. Let me see what I can do about getting a replacement to you...

Thank you for the help and support.
