hy. how can fix the error "no module named tkinter" thanks.

guido57 commented 6 years ago

Hi Unupingu.

The following command should install the tkinter module in your raspberry

apt-get install python-tk python3-tk

Let me know,

Guido

Thanks for your quik response but when i run sudo python MultiPage. py i get the same error When i run sudo python3 Multiple.py i get the error no module ptvsd

guido57 commented 6 years ago

Hi again. Three points:

this project is tested for python3 only, so don't run "sudo python MultiPage.py"
in my experience sudo is useless
yes, to run my code you need ptvsd module also but you don't need it, unless you want to remote debug with Visual Studio. More info about ptvsd here Remotely debugging Python code on Linux with Visual Studio For these reasons you just need to: 1) comment out the following lines: # print("ptvsd.enable_attach('my_secret')") # import ptvsd # ptvsd.enable_attach('my_secret') 2) run: python3 Multiple.py

guido57 commented 6 years ago

Of course, let me know your progress 👍 Bye

unupingu commented 6 years ago

no its not working.i get this error.

pi@raspberrypi:~/MyThermostat/Raspberry $ sudo apt-get install python-tk python3-tk Reading package lists... Done Building dependency tree Reading state information... Done python-tk is already the newest version (2.7.13-1). python3-tk is already the newest version (3.5.3-1). 0 upgraded, 0 newly installed, 0 to remove and 53 not upgraded. pi@raspberrypi:~/MyThermostat/Raspberry $ python3 MultiPage.py File "MultiPage.py", line 13 from tkinter import Tk, Button, PhotoImage, messagebox ^ IndentationError: expected an indented block

guido57 commented 6 years ago

Ok, two more points:

Because you commented the three lines above, you have to comment the "if" statement also. So modify MultiPage.py in such a way:

# if os.name == 'posix':
#    # on raspberry
#    print("ptvsd.enable_attach('my_secret')")
#    import ptvsd
#    ptvsd.enable_attach('my_secret')

I forgot to place AnimatedGIF.py on github, but now it's present and you can download it.

Go now!

now i have this error

unupingu commented 6 years ago

do you have a image builded of this project that you can send me.

guido57 commented 6 years ago

Hi. Well, I think you are just a millimeter far from the finish line!

You don't have a screen attached to your Raspberry, do you? or
you have it, but you're executing python3 MultiPage.py from a remote shell, haven't you?

The error "no display name and no $DISPLAY environment variable" comes out when there's no X11 (Unix/Linux standard graphic interface) configured or when Raspbian doesn't know which display to use. For this reason, even if I send you a working Raspberry image, you have to solve this problem all the same so:

attach an HDMI screen to you Raspberry and reboot
or connect a TFT Screen as I showed
or activate "VNC server" on your Raspberry doing sudo raspi-config and connect to it with any "VNC client": this generated an X11 server automatically

In any case, if you run from a remote shell, enter: export DISPLAY=:0.0 just once

Bye

IT WORKS!!! (:(: THE FILE THAT I HAVE TO UPLOAD (thermo. lua)TO THE ESP8266 ,I HAVE TO CHANGE SOMETHING ?LIKE SSID/ PASSWORD.

guido57 commented 6 years ago

I'm very happy to know that. To connect your ESP8266 (with NodeMCU installed) to your local WIFI network simply do this, changing SSID and PWD with yours.

-- Connect to Wi-Fi network wifi.setmode(wifi.STATION) wifi.sta.config(SSID, PWD)

-- Wait for a few seconds and then check your ESP8266 obtained an IP address print("Connected to network " .. SSID) print("IP: " .. wifi.sta.getip())

After that, ESP8266 NodeMCU will retain these setting and automatically connect to your WIFI after any reset. Just to be safe, simply do: wifi.sta.autoconnect()

unupingu commented 6 years ago

where do i put this wifi.setmode(wifi.STATION) wifi.sta.config(SSID, PWD) i dont find them nowere

guido57 commented 6 years ago

Well, to answer your question I need to know the environment you're using to program your ESP8266 NodeMCU device. I'd suggest ESPlorer for Windows. You need to execute those commands only once, so you can:

digit them in the command line of ESPlorer one line by one.
or you can place them in a file named, for example, wifi.lua and launch it only once

unupingu commented 6 years ago

I use ESPlorer After lunching wifi.setmode(wifi.STATION) wifi.sta.config(SSID, PWD) Then i have to lunch thermo.lua and init.lua. ?

guido57 commented 6 years ago

Yes. Launch: wifi.setmode(wifi.STATION) wifi.sta.config(SSID, PWD) To be sure ESP is connected to the wifi, check the obtained IP Address for the ESP with: wifi.sta.getip() If everything is ok you'll have something like: 192.168.1.111 255.255.255.0 192.168.1.1

Now go to the Raspberry and take note of its IP Address, i.e. 192.168.1.69 Change line 84 of thermo.lua with url = "http://192.168.1.69:2048"

Now, for testing, simply launch, using ESPlorer: thermo.lua Raspberry should receive the measured temperature and show it on the screen once.

I'd suggest to configure your router to reserve always the same IP to your Raspberry
