im genuinely amazed how good this is, i just cant believe this works so well. But the question is, i can read the code and understand how it gets the data , and i can understand it put the data into hi memory. but where in the program does it get the data? what put the info into the memory?


thanks

oh right that looks interesting too!

the bbc basic one reads info from the bbc news website, and sniffs for the good bits. I know a little bbc basic, my brother knows a lot more but only last did it 20 years ago, and we both where just reading the program, but could not see what puts the info into memory.


works very well!

Incidentally, you can also use the same feed to generate a proper teletext signal for your TV or Acorn teletext adapter from a raspberry pi using vbit2. Installing the Ceefax feed is an option in the new simplified configuration tool.

yes i saw that before! looks really good.


This all came from i was asking my brother about my pi project, that is to remotely open windows and curtains with motors with the pi. Eventually getting it to work some how with my android phone, so this reading the data from the internet is really interesting. =D>
