Hi All
Firstly
i
would like to thank Ian L and Tony T for their help and patience in getting
my pc to send xap messages......
Yesterday i spent from
7.00am to 11.00 pm on this and like Ian Bird had a very frustrating
day.
At the end of the day i had something
happening
,, i can now capture the raw xap message and display it on my tv using
19200
baud (16F876 pic ). At the moment im going to use a look up table for the
fixed part of the message, although i was thinking of having 2 one for
lower
case and one for upper, as i understand the message is not case
sensitive.
Its slow at the moment but hopefully
with
more experience it will get better...
More Soon
