64x64 led matrix panel daisy chaining ????

Post by tolisn »

Hi, We are using the adafruit 64x64 LED matrix panel (part 5362) along with the ESP32.
At this time we go one panel to work showing text but we are trying to do the following with no success.
1. Load a color Jpg file
2. Daisychain 2 such panels together.
Can anyone help with this ?

colour JPG - no, only palettised BMP are supported.

Daisy chaining depends on how you want the resulting panel to look i.e horizontal or vertical.

I don't know if there's a height/width limit but if you use a displayio.Bitmap using RGB565 (1 int per pixel) your display will need 128*64*2=16384 bytes


```
from adafruit_matrixportal.matrix import Matrix

# horizontal
matrix = Matrix(width=128, height=64,tile_rows=1, bit_depth=6,serpentine=False)

# vertical
matrix = Matrix(width=64, height=128,tile_rows=2, bit_depth=6,serpentine=False)
```

Serpentine is how the panels are wired. False means the panels are oriented the same way (ribbon cabling is longer though)

Hi and thanks for your time.
Actual we are trying to load an image that is two to three colors at the most. How can we do this ?
Also can you point me to the right direction regarding the daisychaining. We are trying to connect two 64x64 panels side by side. Where do we start and are there any libraries available to work with and what additional hardware do we need ?
will an ESP32 be able to cope with it ?
