Thanks for your help!
I have to execute the command in sudo for the LEDs, but it works fine! So, I will execute a chmod command after boot time.
Thanks for your help!
I have to execute the command in sudo for the LEDs, but it works fine! So, I will execute a chmod command after boot time.
It works fine with the last beta image! Thank you!
I'm also able to get digital input 1_01 state with the following command
sudo cat /sys/devices/platform/unipi_plc/io_group1/driver/di_1_01/di_value
Is there a way to turn on/off user LED with SYSFS too?
Of course! Here is the entire dsmeg output

It worked! Thanks for the explanations.
With these OpenSource Images is there a way to access to digital inputs and user LEDs directly in python without using Websocket or REST API?
EDIT
It only works when the RS485 wires are not connected to UniPi at boot time. If I connect them after it works but when they are already connected the RUN LED blinks. Here are the diagnostic messages:

EDIT2
A simple *sudo reboot" is not enough. To fix the situation I need to
So it seems that the issue is due to Neuron extension and not the raspberry pi
Hi Tomas,
Thank you for you answer! I tried to use your last image but it doesn't work. The RUN LED blinks with a period of 4 seconds and I can't find any additional serial port.
Also, the README file explains that the FileSystem should be mounted as "ReadOnly upon every boot" but it is ReadWrite...
Hi guys,
I'm trying to read the data received from RS485 with a simple python script but I connect to the port. Here is the snippet
import serial
ser = serial.Serial("/dev/extcomm/1/0", 19200, parity=serial.PARITY_NONE, stopbits=1, timeout=3)
while True:
c = ser.read(1)
print c
And here is what it returns
Traceback (most recent call last):
File "test.py", line 3, in <module>
ser = serial.Serial("/dev/extcomm/1/0", 19200, parity=serial.PARITY_NONE, stopbits=1, timeout=3)
File "/home/pi/test/venv/local/lib/python2.7/site-packages/serial/serialutil.py", line 240, in __init__
self.open()
File "/home/pi/test/venv/local/lib/python2.7/site-packages/serial/serialposix.py", line 268, in open
raise SerialException(msg.errno, "could not open port {}: {}".format(self._port, msg))
serial.serialutil.SerialException: [Errno 13] could not open port /dev/extcomm/1/0: [Errno 13] Permission denied: '/dev/extcomm/1/0'
I already tried to add the user pi to the group dialout but it still doesn't work! I must use sudo to access to my RS485 data.
How can I modify that?
Thank you very much
EDIT : I'm using Evok 1.0
