and after install i try to execute the example:

python/matrix-cpu.py 
Traceback (most recent call last): File "python/matrix-cpu.py", line 4, in <module> import max7219.led as led ImportError: No module named max7219.led

this is the code into the python file:

#!/usr/bin/env python

import os
import max7219.led as led

def getCPUtemperature():
res = os.popen("vcgencmd measure_temp").readline()
return(res.replace("temp=","").replace("'C\n",""))

device = led.matrix(2)
device.orientation(270)

try:
while True:
device.show_message("CPU temperature: " + getCPUtemperature() + "C");
except KeyboardInterrupt:
pass
finally:
device.clear()

any help…?

fixed the issue, seems that it was incorrectly connected, i have swapped the pins of leds and now works!!!

thank you so much @rm-hull for your support!!! by the way, any python file with rss and clock…?

[doreks]

sure, the first picture is just with led.matrix connected to the raspberry pi.

and that other picture is the running sudo python matrix_demo.py, from directory luma.led_matrix/examples:

it’s moving but doesn’t show nothing clear to read
