I have a 32x32 matrix connected to an Arduino Uno (running firmware rev. 0001). I loaded up the example colorwheel_progmem_32x32 and made the following change:
However, upon running this, the LEDs simply start behaving in a seemigly random fashion (like what you would see on the panel when a program is being loaded onto the Uno). Further calls to draw functions don't have any effect.
I did some debugging and discovered that upon commenting out these lines in RGBmatrixPanel.cpp, the issue disappears.
