P10 SMD RGB 32x16 display not properly displaying

Open tammaaziz opened this issue 6 years ago • 10 comments

Hello! I have a P10 rgb full color 32x16 display : I tried all available options (display(A, B, {C}, {D}), setScanPattern, setMuxPattern) on the subject using the PxMatrix library with a NodeMCU (ESP12).

beside, I tried the display.setPanelsWidth(4) as suggested by pyzimmer but does not work .. I am really stuck !! Can anyone help please !

Hi...could you post a picture / gif of what's going on?

Hi.. Thank you 2dom..

I just uploaded a youtube video of the display result of the "pattern test" sketch : I am using a NodeMCU ESP 12N. [https://www.youtube.com/watch?v=dQBQuWF_Xp4]

Just to mention that I have already tried using Wemos D1 (with same PxMatrix Library) but also RGB Matrix library using Arduino Uno : all the results are not ok.

hello Dominic,

I hope you are doing well,

Did you get a chance to check my response ? if so, is there any guidance, anything I can check/do please ?

Thank you

did you try display.setMuxPattern(STRAIGHT) ?

2dom avatar Jun 12 '19 19:06 2dom

Hi,

The same result : I have also tried the different scan patterns + ratios : (almost) same result.

really stuck !!! Any idea please.

tammaaziz avatar Jun 13 '19 21:06 tammaaziz

Hi,

I tried the following and the result is now different..but still cannot display numbers or words.. I did like this :

  • remove the B, C and D pins from Panel
  • set scan rate to 2 .. as only A pin is connected which gives 2 states.
  • use displayTestPixel instead of displayTestPattern

the result is in the link https://youtu.be/Z3agz-ws9vw

Here is the complete sketch used

delay(1000); }

void loop() { delay(100); }

This display appears to have some new strange scanning pattern. You could try setScanPatter(VZAG) but I don't think this will do the trick. This panel is most likely unsupported by PxMatrix (sorry)

2dom avatar Jun 15 '19 16:06 2dom

Hi,

I have already tried that one too, no success !!! What about giving me hints to adapt this new pattern to the library :do you think this is possible ?

thanks

Apart from reading the Readme and the code not much unfortunately - it's a bit of a mind bender.
