"./paparazzi" to run the Paparazzi Center
Select the "Microjet" aircraft in the upper-left A/C combo box. Select "sim" from upper-middle "target" combo box. Click "Build". When the compilation is finished, select "Simulation" from the upper-right session combo box and click "Execute".
In the GCS, wait about 10s for the aircraft to be in the "Holding point" navigation block. Switch to the "Takeoff" block (lower-left blue airway button in the strip). Takeoff with the green launch button.
Power the flight controller board while it is connected to the PC with the USB cable.
From the Paparazzi center, select the "ap" target, and click "Upload".
