I am getting a slow rocking right then left when flying in a straight line between waypoints, also when flying alt-hold.  Its not making for the best videos on long flights, is there a way to adjust…Continue

STB_PIT_P and STB_RLL_P

My Iris has STB_PIT_P value of over 7 and STB_RLL_P of over 10 and Droneshare flagged them as bad entries. The APMCopter manual says values of 3.0 to 6.0 are the acceptable range. I wondered if…Continue

LED lighting for Quad via Arduino

Started by Scott Hallahan. Last reply by Allen Merrell yesterday. 2 Replies

Hello all, Thought I would share my concept of LED lighting for my recently built Quad. I decided to wire up an LED strip with an Arduino mega. With the Mega board I am able to control the flashing…Continue

Hi Chris,

Still giving a compile error for the 1280 board with those two lines :-(

Try this, in the APM_Config.h

Uncomment this line (remove the //): 

//#define LOGGING_ENABLED DISABLED

add the line: 

#  define CLI_ENABLED DISABLED

I'm assuming you already know how to compile the code with Arduino? If not, instructions are here

Is that just a matter of deleting certain files before uploading with arduino? Any wiki on doing the trimming?

F11: Yes, if you already have a compiled hex file, you can load it with Control-F in the MP. If you don't have a hex, you'll need to use Arduino. 

I think 2.7.1 can be run on the old 1280 if you disable the CLI and datalogging. (I don't have a 1280 anymore, so can't check)

Comment by steve F11music.com on August 12, 2012 at 5:25pm

Is it possible to fit 2.7.1 on the 1280? I know I can't upload it via MP but can I strip out some things like logging so that it will fit?

Also is there a way to upload older versions of the firmware using Mission Planner? I recall something about holding an option key down or something when clicking on firmware but I'm not finding it.

@Leonard,

     Re using the sonar and the optical flow, there should be no problem.  Really the sonar is for vertical position hold, the optical flow sensor for horizontal hold.  The interface is also different - the sonar uses an analog voltage while the optical flow sensor uses the SPI bus.  So, all in all, shouldn't be a problem.

Comment by Leonard Gunter on August 9, 2012 at 5:30pm

i have my sonar mounted on the new 3dr mount is it ok to mount optical flow sensor on it also or will there be interference

I'm interested in using four digital (vs analog) led strips to do a sort of animation along the arms of my quad.  The LEDs would light sequentially from outside to in when the quad was descending and inside to out when it was ascending, with the speed of the animation being dependent on the speed of altitude change. 

Do you think the jDrones board handle that?

As a "use case" for the LEDs I am trying to achieve the following:

- Copter Visibility, also for night flying

- Ability to see when a LiPo is plugged in (power-on light)

- Navigational/orientation aid (red/green/white LEDs to distinguish left, right and forward)

- Motors armed or disarmed indicator

- Low voltage warning

- Perhaps flight modes too

Bought 4 myself to start with. Just waiting on APM2.5s arrive. Plan is to have the flashing dependant on the current flight mode using mavlink and a few solid on for observation assistance, all powered from 3S LiPo.

I'll let you know how it goes with some detailed instructions if i can.
