update charset stuck about arducam-osd

[GoogleCodeExporter]

What FTDI cable are you using? Looks like it isn't updating the CharSet due it 
don't reset the board from cable. Please check on Windows if the com port has 
enabled the checkbox for "Set RTS on Close".

i am doing the reset manually.
i press the read\write\update commands in the software then immediately press 
the reset button.

it seem to work now but ive got another problem.
if i dont connect the minimOSD's TX pin to the APM (because i have the xbee) it 
won't start sending Mavlink messages.
if i connect the OSD's TX to APM even on startup it gets the data and then i 
can disconnect it and it will keep sending the data

So, your XBee isn't linking the APM board to a GCS properly. The GCS (or the 
OSD, by its TX) needs to request rates (what MAVLink msgs and at what 
frequency). Please, you need to test the GCS connected through two Xbees First 
without OSD.

That will work.

but what happens if i want the OSD to get the data when i fly without the 
ground xbee ?

i believe a quick solution will be a switch to select either OSD TX pin OR XBEE 
TX pin will be connected to APM.
that way i can switch between ground station to OSD.

while i should still be able to get the OSD data when in ground station mode 
and vice versa

When you fly without the Ground Xbee, you need to connect TX from OSD to APM. 
It is not a limitation of the OSD, it is a limitation of sharing the same 
serial port. Furthermore, it's a limitation of ArduCopter only. ArduPlane saves 
the previous requested rates, so that problem don't affects it.
Anyway, your idea about adding a switch between them is interesting hacking, 
though it can't be switched in flight without extra hardware and a free rc 
channel.
