I've tested this and it might work for your application. Add this to /etc/network/interfaces auto wlan0 iface wlan0 inet dhcp wpa-ssid "MySSID" wpa-psk "MyPassphrase" Reboot. This will cause the dhcpcd service to fail. Insure your OS is up to date. sudo apt-get update sudo apt-get upgrade Install th...

No-IP is a DDNS service. You still need to be able to get access through an IP/port to your router./RPi.

So if I type "wind_chill_max = 0" at the top of the code does this mean its a global value and not local?

Sorry for the stupid question, I'm still trying to get my head around Python after using C for many years.

Yes. That is what you want by the looks of your code.

SurferTim

Or you can use a min / max function: wind_chill_max = max(wind_chill, wind_chill_max) No joy with that one either, I've just read the error again and it is saying; Unbound Local Error: Local Variable 'wind_chill_max' referenced before assignment No idea what it means but its trying to tell me somet...

SurferTim

Code: Select all

wind_chill = 0
wind_chill_max = 1

if wind_chill < wind_chill_max: 
	wind_chill_max = wind_chill;

SurferTim

Add this to the top of your code.

Code: Select all

wind_chill_max = 0

Edit: ...or whatever default value you want that to be.

I'm trying to connect my raspberry pi3 to my laptop using an ethernet cable. I've got both computers on the same ip subnet (169.254.109.1), but with ping I get an 80-100% packet loss and most of the packet that do return take several hundred milliseconds (a few take less than 2ms). The packet loss ...

Maybe they don't allow hosting websites on residential connections? I haven't seen anything explicitly stating this. Any ideas? Yes. Check your ISP's terms of service agreement. Normally residential customers are blocked from hosting websites. Your ISP may consider that commercial. You might want t...

Open /etc/dhcpcd.conf with a text editor. Look for a section that starts with
interface wlan0
If it is there, post that section here.

SurferTim

You have no default gateway. How does your RPi get its network settings?

SurferTim

And the output of route is...?

SurferTim

You must have a routing problem then. Post the output of these:

Code: Select all

ifconfig
route

SurferTim

This should not generate a permission error.

Code: Select all

cat /etc/resolv.conf

SurferTim

That is a dns resolution error. Check the /etc/resolv.conf file.

SurferTim

In addition to DougieLawson's suggestion, run top to see if you have a memory leak.

Code: Select all

top

SurferTim

You might try a masquerade on eth0. I don't have your PLC to test with, so I haven't tried this.

Code: Select all

sudo iptables -t nat -A  POSTROUTING -o eth0 -j MASQUERADE

SurferTim

I'm not using the onboard wifi, but mine seems to work if in /etc/hostapd/hostapd.conf, set

Code: Select all

channel=acs_survey

SurferTim

Check the status of the dnsmasq service.

Code: Select all

sudo service dnsmasq status

If it shows active (running), then it should also show the IP assignments issued.

SurferTim

Opening a browser and entering any domain name, for example, wwww.xyzzy.net, should then bring up the web page which the Pi's local web server delivers. If this is the case, your install/setup failed. Edit: ...unless you are using this as a captive localnet (no internet access). I presume this reso...

For python3, use idle3.

Code: Select all

idle3

SurferTim

Use python3.

Code: Select all

python3 --version

Then what is your question? At even 20ms accuracy, you should be able to time 50fps.

SurferTim

You should be able to connect it. USB is 5v.

Hi.. I m trying to connect a gps module to raspberry pi 3.. but the gps module has RS232 12V DB9 port and I have a USB-rs232 adapter. So I have a doubt if I can connect the module directly to pi's USB port using the adapter. Or do I require a voltage level shifter or something because the power sup...
