trying to run a 4 x 64x64 in a square setup

MythicalForce commented 3 years ago

Command Running

sudo ./demo -D0 --led-rows=64 --led-cols=64 --led-chain=4 --led-slowdown-gpio=2 --led-multiplexing=0

Matrix Setup

3 - 2 1 - 0 <---- adfruit-hat connects here

Note

in the terminal i can see that it thinks it's a "256x64".... and not "256x256"

You probably want to enable the u-mapping if you have that layout https://github.com/hzeller/rpi-rgb-led-matrix/tree/master/examples-api-use#remapping-coordinates

so i added --led-pixel-mapper="U-mapper" and i got this

and in the terminal it says "128x128" when it should be "256x256"

MythicalForce commented 3 years ago

@hzeller so i flipped the bottom 2 boards arround and now it works all that remains is to figure out why there are these lines

just another question!

i wanted to make this work https://learn.adafruit.com/raspberry-pi-led-matrix-display/software but sadly it states that this does NOT work with Pi4 that im using :(

hzeller commented 3 years ago

This is because adafruit uses an ancient version of my library. Just use this one and you're good.

if you have four panels with 64x64 in a square, you get 128x128 ... 256x256 would be 16 panels.

hzeller commented 3 years ago

For the double line situation: did you play with the --led-row-addr-type to see if one of the settings works ?

huh? use the current version of rpi-rgb-led-matrix ? but i would need to write my own code to mirror the desktop on the matrix display?

i want to display video/youtube on the matrix

hzeller commented 3 years ago

the Adafruit framebuffer thing uses my library, but they link in a three year old version that doesn't support the PI4 yet. If you upgrade that submodule to the latest version it might work, though you might need to do some adaptions.

If you just want to watch videos, it is probably easier to use the video viewer in this project https://github.com/hzeller/rpi-rgb-led-matrix/tree/master/utils#video-viewer

teste this now and the closest is 0 :S

You need to update (yourself) the rpi-fb-matrix library from github. That library uses an old rpi-rgb-led-matrix library version. To do this, search some function calls, just read the error messages to do so.

Best regards...

I did it a few months ago, I'll try it again this week, taking dust out my rasp-4 2GB, I will share my mods with all here to continue the free-common-source-coding spirit....

I just saw your video, but in it I can't see the command used, share it please. Also, your hardware, what RPi are you using?

Thanks in advance

davemaster commented 3 years ago

in this cases, the best way to start is trying one by one with those modules: works for ONE, then, WORKS for all. Share also your configuration file... It will be great

I have a 4 chain 64x64 horizontal but use --led-gpio-mapping=adafruit-hat-pwm

davemaster commented 3 years ago

OK,

Divide and conquer- Had You tried your adafruit HAT with only one panel? If it is a 64x64 need some MOD. Then, try with 2, then 3 panels. The thing is, I use the dragon active board....

try.... only ONE PANEL, and share picture

realy you got it working directly from the adafruit guide?.... on a Rpi4?

but you have a dragon board and no the adafruit hat?

davemaster commented 3 years ago

A couple of years ago. Works perfectly (on RPi 3) but with some flickering. My screen are 4 32x32 panels from sparkfun.com (1/16 identical that those in Adafruit)

I follow step by step the adafruit learning guide, there was a matrix.cfg file to define your screen configuration.

Today I will receive new microsd memories, then I will repeat that "recipe" using my RPi 4 - 2GB, and my screen 64x64 (arrangement 2x2 panels)

Best regards
