In Stretch you don't use /etc/network/interfaces to assign network settings. That is done in /etc/dhcpcd.conf.
How is this done?
e.g.:

Code: Select all

interface wlan0
static ip_address=192.168.1.123/24
static routers=
static domain_name_servers=

this works as well for stretch - even there is /etc/network/interfaces part included.

unfortunately i have no proper WiFi USB dongle on my RPi2 - my WiFi USB dongle does not support AccessPoint mode :x
maybe yours too.

Re: raspberry pi problems in industries

it all depends on how tuff/rough/harsh the environment is, where the RPi is opperating in and the individual usecase. a nice industrial looking case or a case made to mount on a "DIN rail" in a "control cabinet" does not change the specification of the RPi itself and does not make the RPi more robus...

Re: How to control two or more nema 17 stepper motor(s) using raspberry pi?

you can use something like this... https://blog.protoneer.co.nz/raspberry-pi-cnc-board-hat/ so the RPi is sending kind of koordinates to an arduino. then the arduino is doing the signal processing to control the stepper driver. but in the simplest case you can control the stepper driver directly via...

Re: Connecting 5 white LEDs to raspberry pi for remote on/off

It appears your LEDs are connected in parallel, as white LEDs normally operate at 3.3 v with a forward voltage of 20-25mA you will have a current draw of 100-125mA. I thought, if the LEDs are parallel, you do not have to limit the current to 100-125mA, you still have to limit the current to 20-25mA...
