The project streams live RSS feeds over the web and displays it on the Text LCD. The Hardware connections are simple. The Text LCD was hooked up to the following pins:
GND to 0V
Vcc to 5V
Vo to 0V via 1k resistor
RS to p10
RW to 0V
E to p12
D0,D1,D2,D3 not connected
D4 to p15
D5 to p16
D6 to p29
D7 to p30
Following are the connections for ethernet (connectors from from Sparkfun):
P8 to RD-
P7 to RD+
P1 to TD-
P2 to TD+
A webpage containing the RSS news feeds was downloaded and entire page was scaned for <title>, the text after it i.e the news was displayed in a rolling fashion. The functions from the "EthernetNetIf.h" "HTTPClient.h", more details on the code. The code extracted 512 bytes from the webpage and extracted the text from the webpage.
All commented lines on the code are the debugging points, where we stuck for a while.
The current code displays the CNN Technology news feeds.
