I am trying to setup a scrolling ticker display on a Raspberry Pi with the current conditions from one of my websites, unfortunately my coding skill is low!!!!

I have got the ticker bit sorted it's just the rss file I can't figure out.

I did some searching in the forum and came up with the file below.

I am getting CMX to upload and process the file as an extra web file.

However when displayed via the ticker no variables (ie temp ) are shown.

I know the ticker is working as it displays an rss feed from the Metoffice perfectly.

<?xml version="1.0" ?>
<rss version="2.0">
<channel>
<title>Long Sutton Weather</title>
<description>Current Conditions</description>
<link>http://angteck.co.uk</link>
<item>
<title>Current Temp</title>

And just to clarify further the ticker will be displayed an a Raspberry Pi Sense Hat using the following python code

import feedparser
from sense_hat import SenseHat

sense = SenseHat()

d = feedparser.parse("https://angteck.co.uk/rss.xml")

print (d.feed.title)

for post in d.entries:
print (post.title)
sense.show_message(post.title.replace("°","'"))

The XML looks like it has values in it now?

It reads the Metoffice rss feed ok!

But the code above only appears to use the title, the values are in the descriptions.

I am afraid my Python skills amount to Google->Copy->Paste->Google Python Errors

I will need to do some more Googling!!!!

I know nothing about it, but I think you would want...

Code: Select all

sense.show_message(post.description)
But won't that show the messages really fast? You may want a delay in the loop.

Interesting...
Beyond me to even begin to understand, but I do follow instructions and a lot of trial and error. About 10 years ago forum member BCJKiwi (Brian) wrote an RSS script and I had it working on both my Cumulus template and Saratoga template sites. I think some time ago it stopped working and appears to be some deprecated PHP code but it is still being processed and updated by my old CU1 setup http://www.komokaweather.com/weather/cumulusrss.php

Enjoy,

Yes, I stopped using it when it stopped working and I couldn't figure out why :bash:

Many thanks that worked perfectly - my code is now - it has a default scroll speed that is slow enough to read perfectly

import feedparser
from sense_hat import SenseHat

sense = SenseHat()

import time

d = feedparser.parse("https://angteck.co.uk/rss.xml")

while True:
