I have the arducopter kit with all the stock equipment.
I just finished configuring the RX/TX in the conifgurator and everything worked perfectly.
I know I have RX power because I have a red light on but I cannot arm the motors at all.
I unplugged the copter from the usb and put a LiPo on. The boards boot and the Green light is solid. I get no RX TX light, but when I turn on the TX the PPM LED blinks fast, when the TX is turned off the PPM light blinks slow. I also hear a series of beeps when I power up the copter.
Any suggestions of things to try?
Could it be that I have not calibrated the ESC's?
I havent figured out exactly how to calibrate them. I am unsure what the wiki means by plugging in each esc to the throttle channel of the RX.
Have you move the throttle to the lower right corner to arm the motors? The A led should behave as follows;
After initial and successful boot this LED will be on, and it is safe to move your quad.
Also is your altitude hold off? I am not sure but I think that the throttle is disabled when the AH is on.
I would highly recommend that you calibrate your ESC's before you attempt to fly. This explains the how to:
Turn your transmitter on and move the throttle to high/maximum. Power your receiver with either a power source or a receiver battery of the proper voltage. Plug the three lead bec/esc connector into the throttle channel of your receiver and then connect your lipo to the esc. You will here a series of chirps from the motor. Once you hear the chirps stop, move the throttle to low/minimum. You will hear another series of beeps. Disconnect the lipo and repeat for each motor individually. If the beeps do not stop, then go back and start over by reconnecting the lipo with the throttle on max. Once you have completed the motors individually, you can reconnect all of them to the power distribution board and you are done.
I appriciate the explination. I got the ESC's calibrated now.
The Green LED is solid and I move the throttle to the bottom right and nothing happens at all.
Are the motors/esc supposed to beep at powerup each time? They beep for a moment and then stop.
I would try to adjust your throttle travel lower on the low side. You can use the trim adjustment to see if it will arm after increasing the bottom travel to a negative number from zero. The motors should all beep at power up then stop. The ArduCopter ESC's last beeps are the number of cells on your lipo. I do believe that you have to hold the throttle for a few seconds to get it to arm. This is a fail safe to prevent accidental arming of the motors.
Ok awsome, I got the motors to arm after playing with thigs a bit.
Now though to arm the motors I am having to move my throttle stick to the BOTTOM LEFT.
Also once the motors are armed, the motors are turning continuiously even with the throttle all the way down. Is this normal?
Thanks for all the help guys, hopefully I will get off the ground tomorrow.
John I am a little concerned that you had to move the yaw to the left not the right per the wiki.
"Arm the motor output by moving the throttle stick to the lower right."
I would check to see if you need to reverse the yaw channel on your transmitter. Before your first flight check here: http://code.google.com/p/arducopter/wiki/Quad_Testing. It is normal for the motors to turn slowly once you have armed them. Remember to turn them off you have to move the stick the opposite direction that you used to turn them on. I would also advise to take it slow. Before you lift off, get the ArduCopter light on the landing gear and see if you can slid it in all directions. This will confirm that your controls are set up correctly before you take off and have an unfortunate surprise. Good luck on your maiden flight. Let us know how it goes.
are you sure you programmed yaw in the right direction ? This is a common issue on helis.
When yawing to the right, the nose should go to the right, not the tail.
About motors they should not rev at minimum, when armed. This could mean that values between your tx and APM does not match.
I tried a different ESC and had this behavior. It seemed to me that ESC, when calibrating was reding APM low thottle value (1000us), not TX (1100us). So when I armed the APM motor was turnig. I never had this with original ESCs.
My throttle stick is moving my Yaw and Roll. I boght a turnigy 9x mode one and switched it to mode 2. I set the controller for "stick"(mode) 2. now things are backwards on all 4 modes or sticks when I pick them. Any one have this problem with a turnigy TX?
Well back to the drawing board. The board isn't booting again for some reason. The lights flash but it never boots. I tried reloading the code on the board but it is still doing the same thing with nothing plugged in. Going to have to start from sratch and see where I get to. Is there any way to wipe the APM clean?
first of all, which code are you using, RC_1 or NG ?
RC_1 from the link in the wiki.
Basically I had everything together, the board was booting properly and I even got all 4 motor to arm a few time, the controls on my TX were all mixed up but it was close. I let it sit over night and the next morning the board will not boot.
I reloaded the code to the board, but never got a good boot (Green LED solid) once. The three lights all flash at once, the RX light flashes a few time, and then the three lights flash again. I never see the racing pattern that usually shows the board is booting and I was getting no response from the motors when trying to arm them.
I took the board out later Sunday and have been trying to just reload the code through arduino. I loaded it and the console shows a good upload, but it still does not boot. I will be trying again from my own PC when I got home this evening. I am hoping that it was just a matter of a bad driver on the laptop I had this weekend.
I was wondering though if there is any way to see is loaded on the APM or any way to format the board to start from scratch. Or is the board using EPROM memory and each time you upload to it, it erases whatever was there before?
"Or is the board using EPROM memory and each time you upload to it, it erases whatever was there before?"
in fact it uses a flash memory but yes, it removes everything which was on there before
check your solder connections between APM and shield
I checked all my solder joints and also tried to reload the code from home. The APM will still not boot properly. When I load the code, everything goes well, and it tells me "Upload Done" at the end. Then the board tries to boot. The three LED's flash really fast and then the TX and RX lights blink a little. The three lights will flash a few more time really quickly and then nothing. I can't get a solid green light anymore =(
Is it possible the boards are fried?
