I'm a student studying electronic engineering in Southampton England,
For my final project of my degree I have been given the task of designing a
security camera control system for use by the general public. The system has
to be able to accept inputs from various sensors such as PIR and IR beams.
When a sensor is triggered the camera moves to point at the position of the
triggered sensor. This bit should be easy, I'm using a PIC chip and a
stepper motor. However......
The problem I am having is that when the camera is triggered it has to send
an IR remote control signal to a VCR hooked up to the camera to tell it to
record. The recording lasts for 2 minutes then a stop signal is then sent.
On switch on the unit has to learn the remote codes so that any VCR can be
used. I.e. by pointing the VCR remote at the unit and firing in the codes
for stop and record.
Does any one know if there are any dedicated IC for encoding and decoding
the RC5 signals so that I can simply interface them to the PIC chip? I know
philips made an IC but it is now discontinued. Could making the PIC store
the codes be the best way to go?
Thanks in advance..
P.s. Does anyone know how available electronic engineering jobs are in
America? I'd like to emigrate after I qualify.
