XVert


Introduction

By default the XVert from Horrizon Hobby is a two-prop hybrid VTOL fixed wing, designed to be controlled with DSMX RC. It features a STM32F3 board, which can be reprogrammed with Paparazzi through SWD. A GPS, magneto en datalink can be added by using the expansion ports on this board so that autonomous flight can be achieved.

Getting started

What you need

  1. An XVert EFL1800
  2. The Hobbyking Joystick
  3. A Black Magic Probe (BMP) or similar SWD programmer
  4. A GPS + magneto
  5. An XBee datalink
  6. A laptop with Ubuntu and paparazzi installed

Steps to follow:

  1. Upgrade the XVert with the XBee and GPS
  2. Install Paparazzi via the one liner to be found here. Just Cut 'n Paste (CTRL+C from webbrowser then CTRL+SHIFT+V in your Linux terminal) and press ENTER
  3. Start Paparazzi Center with the TUDelft configuration
  4. In the Paparazzi center choose "Xvert" in the airframe dropdown menu
  5. Power up the XVert
  6. Connect the SWD pins of the BMP as shown in the image TODO
  7. Press the "Upload" button in the Paparazzi Center, wait...
  8. Plug in the XBee to the laptop
  9. Select Hobbyking in the session menu
  10. Press execute
  11. Select FlightUSB0 in the session menu
  12. Press execute again

Voila, you should get telemetry from your XVert. Now it is up to you how and where to fly.

Something analog on pa5 and pa6?

The CYRF seems to be on spi.

First time flash

The first time the xvert is flashed, some extra steps are required to delete the protected programming.

Black magic probe steps:

  • target extended-remote /dev/ttyACM0
  • monitor tpwr enable
  • monitor swdp_scan
  • attach 1
  • mon option erase
  • load /home/houjebek/paparazzi/var/aircrafts/aaf3d/ap/ap.elf
