Trying to get 64x32 P6 working with Smartmatrix v3


#1

Hi everyone.
I have a project due and don’t have much time left for ordering parts. I’m trying to run a 64x32 panel from a SmartMatrix v3 and am only getting a garbled screen.

I can’t post videos here yet as my account is new but please see twitter @1030 account’s last tweets and you can see what it’s displaying.

I’d be very thankful for any help as the deadline looms closer and I’m very anxious.
Thanks
James

Can you post a link to where you got the panel, or some details? From the video it looks a bit like it’s either misconfigured in the sketch, or a panel the library doesn’t support. e.g. a 32-row /8 scan panel.

Was this working at one point then stopped working, or never showed a clear image?

You could post the configuration code you’re using here. Taking a stab in the dark based on how the matrix is oriented vertically in your photos: if you want to make the screen 32-pixels wide, 64-pixels high, you need to set it to 64 wide, 32 high in the sketch, and rotate by 90 or 270 degrees.

Hello,
attached is a photograph of the board. I got it from https://makersify.com/collections/official-adafruit-uk-distributor/products/adafruit-64x32-rgb-led-matrix-6mm-pitch?variant=1027842753

I’ve tried width = 64 and height = 32 and no luck. Disregard the orientation of the original photos - my phone had rotated the pictures.

(also, I’m the same guy - James Houston & 1030) - two accounts due to a forum problem on my phone)

Thanks very much for any help.
James

Can you try this test program? On a working 64x32 panel, it should show bitmaps on the left half of the 64x32, and might look a bit weird on the right half but still showing something that looks like a bitmap.

What version of Arduino and Teensyduino are you using? Also what version of SmartMatrix Library? What CPU Speed have you set in Arduino (Tools-CPU Speed)?
