Still need help :/
If you run python matrix_demo.py -h
it will show the options. If you have a 4x cluster, try adding -n 4
.
Also, have a look at the documentation, daisy-chaining in particular: https://luma-led-matrix.readthedocs.io/en/latest/python-usage.html#daisy-chaining
@rm-hull Thanks for ur answer.
If i try: python matrix_demo.py -n 4 --rotate 1
It scrolls on only one 8x8 :(
What happens if you take off the --rotate 1
flag?
How have you wired up your 4x "cluster" ?
Any pics of you board / wiring (you can drag/drop images to the github issues text field to upload them), or links to where you bought from would be useful
I bought this one: https://www.amazon.de/gp/product/B079HVW652/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
I can make a video later if this helps
Looks bit like this, but not rly sure. I will test it.
EDIT: I tried `import time
from luma.core.virtual import viewport from luma.core.interface.serial import spi, noop from luma.core.render import canvas from luma.led_matrix.device import max7219 from luma.core.virtual import sevensegment
serial = spi(port=0, device=0, gpio=noop()) device = max7219(serial, cascaded=4, block_orientation=-90)
seg = sevensegment(device) seg.text = "Hello world"`
Its only on one 8x8
Looking at the video it is exactly the block orientation issue.
Try running the demo with python matrix_demo.py -n 4 --block-orientation=90
... if that doesn't look right, try -90 instead
You are right....... Damn it. Thank you!!
Type of Raspberry Pi
Got a RPi3.
Linux Kernel version
Linux raspberrypi 4.9.80
Actual behaviour & Expected behaviour
At the moment i execute
python matrix_demo.py --rotate 1
the text is scrolling on all 8x8 separately and not on my 4x 8x8 MAX7219 as a "cluster".I am rly new to the MAX7219 topic, so please be kind 🔢
Thank you!
