Re: [Paparazzi-devel] Connecting Navilock NL-652ETTL

[Andreas Philipp]

Thanks, Helge!

it works now. I have connected the +5V pin of the gps to pin 11 of H7 on 
the Paparazzi FTDI utility board (which gives +5V), and GND and TX and 
RX to pin 9, 2 and 1 of the H5 on the FTDI utility board:

GPS-pin 1 -> FTDI-pin 11 of H7
GPS-pin 2 -> FTDI-pin 9 of H5
GPS-pin 3 ->
GPS-pin 4 -> FTDI-pin 2 of H5
GPS-pin 5 -> FTDI-pin 1 of H5

After connecting the usb cable and starting u-center in a virtualbox it 
was detected by the u-center software. Great!

Now the rest seems clear ...

Thanks again!
Andreas
