I think you have two big misconceptions here:
So you won't have anything different (also much faster than APM 2.5, also not Arduino), except that you loose the benefit of having a scalable solution with a RTOS and the official 3D Robotics support.
Hi probably not the right place to put this,ive got my PX4 uploaded,it does the com change from 8 to 9 but wont load the mision planner says no heart beats,can some one please help me,Thank's,Marty
I'm not sure what they were thinking splitting things amongst multiple boards.
Maybe someone can comment on that, but to me it doesn't seem like a very smart way to do things. It seems to be kind of a holdover to the pans and shields day of generic multi purpose hardware.
OP was ported to a $10 STM32F3 Discovery board, so if we have to deal with pans and shields maybe something like that would work just as well. I'm guessing someone will do something like this once there's some good STM32 code to be ported.
I still have problems with PX4 board.
1. I can not calibrate acc level with MissionPlaner. It only success via CLI.
2. I have enabled IMU logs but can not download any logs from the board. It tells me Error opening com port.
Does anyone have success with it?
For all interested in flashing Firmware conveniently, there is a new tool called QUpgrade in the Downloads Area. It allows to flash the PX4 default or APM Plane / Copter / Rover Firmware on Windows, Mac OS and Linux with a graphical user interface in a single click. In particular for APM @ PX4 early adopters it may be interesting, since new builds can be flashed with a single click by browsing the Firmware page.
Flew with PX4 flashed with Arduplane. Stabilized and FBW-A mode works fine. Will try waypoint navigation next week. So far looks good. Great work
Hi,i have 2 questions,the first it is o/k to use the usb cable with the PX4 to set parameters,and secondly ive got the PX4 flying well in stabilized mode,but its terrible in loitter any suggestions please ,your's,Marty.
Works fine to use USB cable to set parameters.
What are symptoms of bad Loiter?
Do you have Vibration Damping?
Hi Gary,ive turned the vib dampening up to 98,ive ordered new prop adaptoror's and bearings,is it best to mount it on moon gel,your's,Marty.
Hi Martin, I dont know about that 98 value.
Moon gel or my favorite Kyosho Zeal Gel will work fine.
Use a 1/2" to 3/4' square pad at each corner and hold the board down with a lightly tensioned rubber bad or Velcro strap loosely fastened with light foam between it and the flight controller.
Try Alt hold mode before trying loiter. if it won't hold altitude properly the problem is probably vibration.
If you have SONAR turn it off in Mission Planner, it can work very nicely, but it is its own source of a whole batch of problems.
