Did you select the correct scan pattern?

desiboy17 commented 5 years ago

yes, as my matrix panel has three data lines that is A,B and C. I have selected 1/8 and also tried others i.e 1/16,1/32,1/4. but the best result is 1/8 in which some pixels are missing.

Is there any in the library with ESP32 ? Have you tested this with ESP32 ?

desiboy17 commented 5 years ago

also i have tried different scan pattern i.e. line ,zigzag ,zagziz.

2dom commented 5 years ago

This may be an unsupported pattern ... can you run the pattern_test.ino

desiboy17 commented 5 years ago

this is not a patter ..i have written "Pixel time" and yes i have tried 'pattern_test.ino' too.

my board has only three data lines A,B and C and resolution is 32*32.

2dom commented 5 years ago

Yes ... please run the pattern test sketch from examples and post the result
