Hi All
Well my
hv ir
reciever progress was short lived. I cant get hv to correctly recognise
which rx
is active. When a (stored) ir signal is recieved Homevision scans the
ir
active mux and should detect the active rx. I tried all sorts but no luck .
I
also think now the design is flawed as the ir active signal is only present
for
approx 1 second ,if hv is busy the active signal may be gone when hv does
get
round to scanning the rx mux...
What happens when hv
recieves an
ir signal while say transmitting an X10 signal? Does the ir signal not get
detected?
Im now thinking of using a Pic to detect
which rx is active and using 3 i/o pins as outputs to identify the active
rx .
Homevision when ready reads the status of its 3 inputs (connected to
ir rx
outputs) and determines which rx is active then pulses a hv output to
ACKnoweldge(connected to a Pic input pin) that it has decoded the
Pics mux
outputs . So 4 i/0 pins would be required on hv....
I was also thinking of adding an RS232 port to
the
Pic so that ir active data could be sent say to a pc. Can the Girder
Software
talk to more than one serial port?
Any comments/ideas
