I'm starting this discussion since there's a lot of confusion and lack of knowledge about PID settings and control theory, so, you can find here a table with several different frames, multycopter types and firmware versions in order to let you start flying and tuning your copter. Be aware that this are not rigid values. Each person has it's own configuration and flying preferences, but, if you have an identical configuration, you may start using those values and tune them for yourself. If you'd like to share your configuration, specs and settings, as well as flying tests, weather conditions and videos, I'll try to keep it up to date.
Ok, I have inserted a googledocs file, never worked with this before :) It looks easy, here's the link
I'm sorry to you all following this thread, but the table is a bit outdated since in the newer versions the PID gains have been a bit changed, so I'm waiting for a stable release with the DCM leaning problem corrected as other small bugs, so I can start updating the table with new values.
One way of doing this, is at the config.h file around line 67 where it says "FRAME_CONFIG". After changing you save the file and upload the firmware to your APM via Arduino.
If you're not confortable changing the config file and uploading via Arduino, and are using the Mission Planner to upload your software, in the Mission Planner you can change it too. Here's a screen of where you have to go.
Hope this have helped.
thanks a ton,
Many thanks, wow, just read the article, even i could understand it. super for guys like me who are just a beginners
i have connected APM2 via usb cable to my PC, loaded Mission planner, it shows - APM Planner 1.1.48
but it does not show ArduPilotMega, next to it i have selected com port and baud as 115200.
in the window instead of ArduPilotMega that it is supposed to show automatically, if i click on drop down arrow, i get only 2 options -Arduplane and ArduCopter2.
on the APM2 the Green power light is solid on, GPS blue is flashing, A red is flashing, and C blue is flashing.
WHY IS IT NOT DETECTING ArduPilotMega automatically
Also if i select Configuration/setup, it tells me "please connect first"
WHAT SHOULD I DO.
I HAD EARLIER INSTALLED 1.1.20 PUT THEN SAW 1.1.48 SO UPGRADED IT BY JUST CONNECTING APM TO PC AND CLICKING ON .EXE, SO NOW WHEN I LOAD MISSION PLANNER, IT DOES SHOW 1.1.48
another thing, i dont get the options under configuration that u have got in the screen shot u sent, i am seeing Arduplane, Ardu Copter, Planner, setup,
where as ur screen shot shows Radio input, modes, hardware,battery, Arducopter2, Hel
So what am i doing wrong
Ardupilot Mega is the board type (the Atmel chip). You may install (appart from other) 1 of 2 different firwares. Arduplane wich is designed for fixed wing planes and Arducopter wich is designed for multicopters. If you never had a software installed before, you go to the firmware tab where you choose what firmware you want to install, then, go to the main tab and select the connect (only after a firmware has been installed) and proceed to the rest of the configuration. However, the best thing for you to do is read the manual carefully and follow the steps descibed. http://code.google.com/p/arducopter/wiki/ArduCopter --> if you're using it for a quadcopter or other multicopter. In there you can also find the led patterns and what they mean !
many thanks again dude, dont leave this forum pl till my quad gets airborne, or i will be grounded for life lol, what will i do without u :-)
Could you tell me what the Dip switches are used for on the APM1 board?
They were used in old versions of the code to reverse the output servo channels. They are no longer used, as this is now done in the software.
Thank you. So if they are switched nothing will happen?
