This is my first post here, so all my apologies if I missed a specific rule of the site.
Here is my point : I have a 16x32 Adafruit Matrix with the Hat for Rpi. The hardware part went with no particular issue.I installed the python and software libraries as described in the documentation. I could also run the demos and even control my matrix (display image, scrolling text, both etc...). But I noticed that -when I run a python matrix related program- my RPi3 CPU load is 100% on one CPU which finally leads to system crash after a while.
I did some extensive tests to understand when this does occur, and here is my conclusion : declaring a matrix with the adafruit library loads the processor when I try to use the time.sleep(n) function.
I am not familiar with libraries compilation, but I cannot figure out why just declaring a variable would generate loading issue.
Here is my demo code :
#!/usr/bin/python # This is server.py file
# This Python file uses the following encoding: utf-8
import time
from rgbmatrix import Adafruit_RGBmatrix
matrix = Adafruit_RGBmatrix(16, 1)
while True:
time.sleep(10)
The library used can be found here : rgbmatrix.cc
I understand my question is specific to a trademark but they did not give me any answer on their forum, so I hope a good dev will be able to help me find out what happens, as the time.sleep function is suppose to hold the execution instead of generating a 100% load.
EDIT : This is a bug from Adafruit library... I compiled directly Hzeller led library and the problem was gone.
