Errata

Important.png As shipped, the Lisa/M is set to provide 5V power to the GPS, which is incorrect - it should provide 3.3V power.

To correct this:

  • Disconnect all connectors from the Lisa/M after noting their positions. Note especially the polarity of the 3-wire servo connectors running along the left edge of the Lisa/M.
  • Remove the 4x Phillips-head screws that secure the Lisa/M into the aft section of the electronics bay.
  • On the back side of the Lisa/M, below the main microcontroller chip, note the locations of jumpers JP6 and JP7 as shown in the image at http://paparazzi.enac.fr/wiki/Lisa/M_v20#Jumper_Configuration
  • Verify that JP6 is closed (using an 0-Ohm resistor) and JP7 is open.
  • Using a fine-point soldering iron:
    • Remove the 0-Ohm resistor from JP6 and ensure the pads are not bridged with solder.
    • Bridge the pads of JP7.
  • reinstall the Lisa/M into the airframe and reconnect all connectors.

Instructions and Notes

The Lisa/M has been pre-flashed with the Phase 2 firmware:

  • Rotorcraft (eg, non-transitioning)

Flight Modes

  • Mode 1: Manual (RC direct)
  • Mode 2: Hover Hold
    • Throttle at 50% to maintain altitude; throttle <50% to descend, >50% to ascend.
  • Mode 3: Hover Hold
    • Captures altitude at which Mode 3 is activated. Throttle position sets maximum throttle the autopilot can use to maintain altitude/stabilize.

Software installation

See also Software User Guide.

Follow the instructions linked from the Software User Guide to install Paparazzi prerequisites. For example, using Linux:

git clone https://github.com/psinha/paparazzi.git
  • Check out the ndrc branch:
git checkout -b ndrc origin/ndrc

Hardware instructions

See Quadshot Assembly Manual for complete assembly and setup instructions.

Ground Station User Guide

See http://paparazzi.enac.fr/wiki/Paparazzi_Center for general theory and operation of the ground station.
