New Version of PxMatrix and No Display

[PurelyAbrasive]

I have upgraded to the new version of PxMatrix and the screen is now blank. I have tried other tests and I know the screen works with this version. Can you take a look and see if there is something in your files that may be causing an issue. I am getting serial output with the correct data just nothing on the screen.

Same for me

I haven't compiled this for a long time and unfortunately I don't see how I can find the time to try this any time soon. are there any examples with the PxMatrix lib? do those examples work?

[anthonyjclarke]

Yes samples in PxMatrix Lib work for me!

@anthonyjclarke did you get this fixed? Pattern test works for me in the examples.

[anthonyjclarke]

Not fixed this yet, was going to try 1.7. On my todo list

I bought a new matrix thinking the one I had was toast ;( I'll move to an old version of PxMatrix and see if I can get it back up and running. Ok Got it working again! use this: https://github.com/2dom/PxMatrix/releases/tag/v1.3.0 the latest PxMatrix does not work with the updated MorphClockRemix for some reason (also doesn't work with the original MorphClock)

[lmirel]

it seems the new PxMatrix requires a few new things:

#define PxMATRIX_double_buffer true
#include <PxMatrix.h>

instead of:

#define double_buffer
#include <PxMatrix.h>

then at the end of the loop() function, you'll need:

display.showBuffer();

It might not hurt to have also:

  display.begin (16);
  display.setFastUpdate(true);

in the setup() function, instead of just:

  display.begin (16);

Let me know if this works for you.
