[Paparazzi-devel] ppm radio control modification

[antoine drouin]

Hello

I have replaced the RADIO_CONTROL_TYPE flag from the airframe file by
a "pulse_type" flag  in the radio control transmitter definition file
which can be either NEGATIVE (JR, Graupner) or POSITIVE (FUTABA,
Hitec, Multiplex) as this parameter really belong to the radio control
transmitter and not the particular aircraft.

So, to make it short, in the makefile part of your airframe frile you
used to have something like this

ap.CFLAGS += -DRADIO_CONTROL -DRADIO_CONTROL_TYPE=RC_FUTABA
ap.srcs += radio_control.c $(SRC_ARCH)/ppm_hw.c

remove the  -DRADIO_CONTROL_TYPE=RC_FUTABA

and in your radio control configuration you use to have something like this

<radio name="cockpitSX (easy)" data_min="900" data_max="2100" sync_min
="5000" sync_max ="15000">

change it fo

<radio name="cockpitSX (easy)" data_min="900" data_max="2100" sync_min
="5000" sync_max ="15000" pulse_type="POSITIVE">

or

<radio name="cockpitSX (easy)" data_min="900" data_max="2100" sync_min
="5000" sync_max ="15000" pulse_type="NEGATIVE">

according to the brand of your transmitter
