First_start

First Start:

Wiring:

Here the first thing I did:

• Insert sd card
• plus the ESP-01 on top of the pixracer (for wifi connection)
• plug the power cable and the gps cable

Software

I use QgroundControl V3.5.4 on a linux Mint 18.3 machine.

Install Qground control: https://docs.qgroundcontrol.com/en/getting_started/download_and_install.html|

Then:

• Use Qgroundcontrol to chnage the firmware from Aurdupilot to Px4 ( V1.9.2, July 2019)
• select a random frame : "generic quatrotor X"
• Calibrate sensor ( compass, gyro, accelero, level horizon)
• add some battery specs ( number of cell in serie)
• Adjust some parameters:
  • Sd logging > SDLOG_MODE= from boot to shutdown
  • Sd logging > SDLOG_PROFILE= 19 ( default set + Estimator replay+ High rate)

Then reboot

setting and first run

Todo:

• Learn more about the battery specs , and adjust the battery parameters
• learn if the frame selection has a influence
• reduce battery and wire
• make a case.
