NPIX-4DI4DO and NetPi-Nodered container issues

[Armin@netPI]

Hello Alhammi,

my first question to customers faced with HW problems is always:  are you using netPI's original SD card it was delivered with or are you using any own SD card with own OS like Raspian OS?

Then I have to say that every two to three month I am updating the Node-RED container to the latest Node-RED version. Last change I made last week and updated the Node-RED in the container to version 1.2.2. I cannot exclude at this time, that maybe the new Node-RED version is the root cause of your problem without trying out NPIX-DIO myself with it.

In order to make tests without Node-RED you can use the console function of the portainer Docker Web-UI in the containers overview list

   

Once you are in the console you can use the standard Linux "echo" or "cat" commands to read and write to the GPIOs wihtout using Node-RED

Code:

echo 1 > /sys/class/gpio/gpioxx/value
cat /sys/class/gpio/gpioxx/value

as described here

Since the Node-RED was started an export of the GPIO might not be necessary since Node-RED did that already. So a

Code:

ls /sys/class/gpio/

should list you already the configured GPIOs.

The manual of the NPIX modules you find located here https://www.netiot.com/netpi/industrial-raspberry-pi-3/ to get out which pin is connected to which GPIO.

So first try the manual way.

Thx
Armin
