nsh console running on USB param module running working with i2c and common drivers provided implementation for drv_pwm_output.h i2cdetect working as expected with no device mavlink started succesfully mounts sd card and logger runs logger to file succesfully pwm_servo implemented without using Nuttx lib pwm_out outputs expected waveforms - however currently if the frequency is higher than what the pwm_out driver runs, there will be aliasing, based on how the registers gets resets wifi softap working - Seeing wifi hotspot - cant connect due to wrong password - problems with adjusting ssid and password wifi ssid and password being set accordinglu connected to wifi hotspot with dhpcd - made some changes to nuttx to only build for SoftAP mode, however this was effectivelyy removing the ifdef for STATION mode. Should investigate the coexist option again added ifdef to not use timer 0 when wifi enabled - reverted esp32 rt_timer to make use of timer 0 by default fix setting incorrect bit in hrt timer register - hrt running as expected, but on startup the pwm_out driver starts up at about 200Hz and then rises over a minute or so 250Hz. Not sure if this was present previously, and could be due to Wifi running at time priority on timer 0 pull xtensa compilers in setup.ubuntu.sh revert logger stacksize and cmake argument esp32 chip revision and PX4 UUID implemented spi board reset implemented, formatting checked devkit acts on startup as a wifi bridge for comms - the most usefull setting for the general developer when buying a esp32 devkit - testing Mavlink shell using ./Tools/mavlink_shell.py - todo: Test mavlink messages being forward improve wifi telemetry by increasing prio - Remove power save mode on wifi - increased daemon thread schedule priority to 50 compiles without Nuttx changes - updated compiler settings to match those of nuttx on px4 side add espressif_esp32 to excluded boards ci: allow docker to find xtensa compilers
PX4 Drone Autopilot
This repository holds the PX4 flight control solution for drones, with the main applications located in the src/modules directory. It also contains the PX4 Drone Middleware Platform, which provides drivers and middleware to run drones.
PX4 is highly portable, OS-independent and supports Linux, NuttX and MacOS out of the box.

Release notes and supporting information for PX4 releases can be found on the Developer Guide.
Building a PX4 based drone, rover, boat or robot
The PX4 User Guide explains how to assemble supported vehicles and fly drones with PX4. See the forum and chat if you need help!
Changing Code and Contributing
This Developer Guide is for software developers who want to modify the flight stack and middleware (e.g. to add new flight modes), hardware integrators who want to support new flight controller boards and peripherals, and anyone who wants to get PX4 working on a new (unsupported) airframe/vehicle.
Developers should read the Guide for Contributions. See the forum and chat if you need help!
Weekly Dev Call
The PX4 Dev Team syncs up on a weekly dev call.
Note
The dev call is open to all interested developers (not just the core dev team). This is a great opportunity to meet the team and contribute to the ongoing development of the platform. It includes a QA session for newcomers. All regular calls are listed in the Dronecode calendar.
Maintenance Team
