Re: [Paparazzi-devel] Add serial baudrate option to telemetry downlink

[Stephen Dwyer]

Hi Michal,

You need to change the type declaration in both serial.ml AND serial.mli. Compiles for me on master when I change both.

Hopefully that helps.

Thanks,

Hi folks,

I am reading telemetry from the autopilot through FT232 USB to Serial breakout board (debugging purposes) and I would like to use higher baudrates (e.g. 921600). On the autopilot side it is no problem (Lisa M 2.0), but the Ocaml serial interface does not recognize anything over 230400.

I added new record (B921600) to sw/lib/ocaml/serial.ml and recompiled the GCS, but I got the following error:
OC serial.ml
File "serial.ml", line 1, characters 0-1:

       The field B921600 is only present in the first declaration.
make[1]: *** [serial.cmo] Error 2
make: *** [libpprz] Error 2

Do you know how to correctly set/recompile the paparazzi ocaml library (obviously the file serial.cmi has to be recompiled)?

Thanks!
Michal
