Using a joystick to control twog servo

PC-side configuration

On the PC side we will send actuator commands two different ways:

1. Running an ocaml application that listens to the joystick device and using a configuration file, will send ivy messages that get forwarded to the vehicle by the server.
2. Normal paparazzi settings mechanism (using settings dialog from paparazzi center running on PC) that sets corresponding variables on the vehicle.

Running the joystick test program you can see which buttons do what: (Note you have to run a make in the directory first to compile everything)

Then creating an xml configuration file such as:

paul@ledelle:~/paparazzi3/trunk/sw/ground_segment/joystick$ medit ngs_set_actuators.xml

and now running the input2ivy ocaml application:

export PAPARAZZI_HOME=/home/paul/paparazzi3/trunk
paparazzi3/trunk/sz/ground_segment/joystick/input2ivy -ac TJOVERO ngs_set_actuators.xml

running ivyprobe we can see the message getting transmitted:

paul@ledelle:~/paparazzi3/trunk/sw/ground_segment/joystick$ ivyprobe '(.*)'

shows:

Paparazzi joystick sent  'input2ivy SET_ACTUATOR 1496 2 3'

but we have to make sure the server knows this message needs to be forwarded: in messages.xml the message should be labeled as "forwarded" :

 <message name="SET_ACTUATOR" id="100" link="forwarded">
   <field name="value" type="uint16"/>
   <field name="no" type="uint8"/>
   <field name="ac_id" type="uint8"/>
 </message>

To send settings use the actuators.xml file:

<settings>
    <dl_settings NAME="Actuators" >
      <dl_setting VAR="actuators[1]" MIN="900" STEP="1" MAX="2100" module="actuators" shortname="chan1"/>
      <dl_setting VAR="actuators[2]" MIN="900" STEP="1" MAX="2100" module="actuators" shortname="chan2"/>
      <dl_setting VAR="actuators[3]" MIN="900" STEP="1" MAX="2100" module="actuators" shortname="chan3"/>
      <dl_setting VAR="actuators[4]" MIN="900" STEP="1" MAX="2100" module="actuators" shortname="chan4"/>
      <dl_setting VAR="actuators[5]" MIN="900" STEP="1" MAX="2100" module="actuators" shortname="chan5"/>
      <dl_setting VAR="actuators[6]" MIN="900" STEP="1" MAX="2100" module="actuators" shortname="chan6"/>
      <dl_setting VAR="actuators[7]" MIN="900" STEP="1" MAX="2100" module="actuators" shortname="chan7"/>
    </dl_settings>
</settings>

Vehicle-side configuration

On the vehicle side we are using a twog for hardware so we will use the setup_actuators target found in /conf/autopilot/setup.makefile. This makefile is used by the tiny.makefile which is used because we specify we're using the twog in twinjet_overo.xml

  <firmware name="fixedwing">
    <target name="ap" 			board="twog_1">

The setup target is defined as follows in the airframe (twinjet_overo.xml):

  <firmware name="setup">
    <target name="tunnel" 		board="twog_1" />
    <target name="setup_actuators" 	board="twog_1" />
  </firmware>

If we were adding the joystick to the autopilot code we could instead add the following line to the firmware section:

<subsystem name="joystick"/>

but that's another project...

Here's the setup.makefile section that worked for me:

setup_actuators.CFLAGS += -DFBW -DLED -DTIME_LED=1 -DACTUATORS=\"servos_4017_hw.h\" -DSERVOS_4017
setup_actuators.CFLAGS += -DUSE_UART1 -DUART1_BAUD=B57600 -DDOWNLINK_DEVICE=Uart1 -DPPRZ_UART=Uart1 
setup_actuators.CFLAGS += -DDOWNLINK -DDOWNLINK_TRANSPORT=PprzTransport -DDATALINK=PPRZ 
setup_actuators.CFLAGS += -DDOWNLINK_FBW_DEVICE=Uart1 -DDOWNLINK_AP_DEVICE=Uart1
