I only had a quick scan through the code, but it looks like the update_lcd() function is the one you want to modify? I guess just underneath the LCD.message(msg) you need to add a function which also displays 'msg' on screen? It isn't so easy. Because it is necessary to put the part of the function...

Unfortunately I'm not familiar with these libraries at all and cannot test the program. On a quick inspection it seems that LCD_QUEUE is a queue where you put items into it with LCD_QUEUE.put and get items with LCD_QUEUE.get. If you want to display what you put into the queue, probably the best thi...

Hi guys! I want to improve my gui.

I would like to show the same messages that are shown in my LCD in my gui.

How I could do it? Any idea?

Thanks

dan11

I solved the issue. I did this: • Create the folder home/pi/.config/lxsession/LXDE • In this folder put a file named autostart containing one line specifying the full path of the file to be executed: e.g. python /home/pi/pipresents/pipresents.py <options> • Make the autostart file executable by usin...

Thanks for your answers, the gui is working.

The clock object solved the issue and I've attached the gui code into the radio code and now all is running.

Thanks very much.

Thanks for your reply Sleep. I know where I have to put the calls of the functions what I don't know exactly is what I've to write inside each function to achieve that clicking in the image will be the same that pushing the button on the lcd. Any help please? Because the function used only reads the...

My project uses the script of python of Sheldon: http://usualpanic.com/2013/05/raspberry-pi-plate-internet-radio/ Now I want to control it at the same time with the lcd or with the gui. I've created a code that shows a photo of th...

Por lo que estoy buscando algún altavoz para conectar a la salida de audio de la RPi, si es posible del tamaño má...

Hi!

I'm looking for a small speaker to connect to my RPi. I wish it was as small as possible. It'll connect to the audio jack output.

Any suggestion?

Thanks

Sounds like the wifi driver may not be loading when you boot. Edit: not right if the GUI can start the wifi Before you use the GUI to start your wifi what do commands lsusb and lsmod show? What is the output of file /etc/network/interfaces? You could try this command and see if it makes any differe...

The Adafruit LCD seems to use a HD44780 compatible display - this supports an extended ASCII character set, not Unicode. It should have a '0' superscript character which you could use as the degree symbol. You should be able to print this character using chr(176) like this: lcd.message("Temperature...
