Thanks for writing it... :)
2000-05-17 -+- Brian Harrington -+- brianh@sybernet.ie -+- Hello there,
Nice project. It's almost working for us
with RTAI. The only problem is the data stream we get from
the IR receptor. It's more like a random number
generator than a descernable code. Is there something
we're missing out on?
Best Regards,
Brian
2000-05-22 -+- Brian Harrington -+- brianh@sybernet.ie -+- Hello Ismael,
Thanks for that. I think it would be good to post with the Talkback linux.org article. Our problem was in the end a software rather than a hardware one, ironically. We were missing some of the RTAI functions which implement the periodic task scheduling. RTLinux seems to be significantly simpler in this regard than RTAI.
We are using a Sony remote control to communicate to the IR receptor and it now works fine.
Thanks and Best Regards,
Brian

2001-04-22 -+- anup -+- anup_lonkar@usa.net -+- Hi!
A very nice project.
I would like to know why use Infrared and not any other wireless means like
FM?
All the best.
Thank you,
Anup.
2003-03-03 -+- Dileep -+- kdilip_s@yahoo.co.in -+- hai ,
Its a very nice project ! I need one help in my project , i want to know how to find the battery capacity in labtops (how to read the battery satues and store it in one variable to use futher ) Plese let me know do u have any idea regarding this peoblem ....Do i need to write driver programme if so which driver ....or the linux redhat8.0 will read ....Iam using toshiba satell
ite labtop ....
ok bye

2004-10-31 -+- Ray Brannam -+- raybo@realnet.co.jp -+- The IR is used because the remote control interface to the A/C or Heatpump uses IR already. At least they do here in Japan.
Does anyone have a printable circuit board foil patern?
