Hi there,

please re-check the connections for A,B,C. If this does not work you might want to try a previous version of the driver:

https://github.com/2dom/P10_matrix/tree/788d6760dfeee1bde4ea53fd4c1257c313a92615 https://github.com/2dom/P10_matrix/tree/788d6760dfeee1bde4ea53fd4c1257c313a92615

I recently added some new features to the library and was not able to test it on the 8 row-step display.

Let me know if this fixes it.

Cheers

Dom

Hey,

first thanks for the great source code and the wonderul idea of pin reduction !

I just finished wiring up my display, but I only can see jumbled-up pixels.

The test script "P10_pattern_test.ino" creates the following sequence:

1st line red / 9th line red 1st line yellow / 9th line yellow 1st line white / 9th line white 2nd line red / 10th line red and so on... The second part of the test script (where the text "Pixel" is displayed in cyan) only created non-sense (see picture) https://user-images.githubusercontent.com/3587300/35194616-60d1fe94-feb6-11e7-81ce-ff763511f4ed.jpg — You are receiving this because you are subscribed to this thread.

Hey,

you might have forgotten to change #define pattern4 to pattern8 in the header file.

Best

Thank you for your advise. There was a loose contact in one of the address lines (A,B,C), so that some pixels were overwritten, resulting in the strange behaviour. Now it's working perfectly!

Yay - Glad it works !

Best Regards
