I have a quad copter with an APM 2.5 installed on it. Last week I updated from the stock 2.8.* code to the newest (available through mission planner) 2.9.1. Immediately after update, everything…Continue
I've been trying to do something very similar with a hex that I have available, but I've been having terrible luck with our cameras. I've tried a PowerShot A3400IS and PowerShot SX200IS, but both have struggled to take…"
"Is there any general consensus on what's causing the gyros to die? I just threw out anything I could think of that might have been related, but proximity in time doesn't mean causation. I'd like to keep from…"
"Glad they're going to replace it for you Nathan, I have a APM 2 board with the exact same symptoms, it's never had a servo plugged in anywhere and has only ever been connected through USB and yet the gyro is dead.
There quite a few reports…"
"What an interesting post. I have had 2 APMs die with the same exact symptoms you describe. It was during my first time setting up camera gimbals. I never connected the two events as what might have damaged the APMs. I started with a very small…"
"That is very kind of them.
I agree with your analysis above. Looking over the schematics and board layout all the way back to APM2.0 I still can not find trace connections for the +5 on the PWM Output lines - there are only 8, A0 - A7. A8 - A11 are…"
"After reading quite a bit, I think that I understand how you are supposed to connect the gimbal servo.
Remove JP1 (jumper 1) to disconnect the "output" power rails from the analog and APM internal power rails.
Connect power to the…"
"I see the warning that you cited. Frustratingly, on the AC2_Camera page they show the gimbal's servo connected directly to A11.
As I mentioned previously, unplugging all of the external components (GPS, servos, motors, etc.) still…"
"I've been looking over the board layout (for APM2.5.2) and can not clearly see the +5 connection traces (even with all layers applied to the drawing. There was another warning about where not to connect the servos HERE.
The embedded link takes…"
"I would roll back to the previous configuration (I think that is what you were trying to do/did), no servo connected. In short take it all apart to the point where it was working so we can determine what is broken.
All the 'A' connectors…"
"Just realized I left off one answer.
The camera was being triggered using the "relay" mode, even though there was no relay attached. This just sent +5V down a USB cable to a Canon PowerShot running CHDK. The S and -…"
"And here I thought I'd given every piece of information possible :)
Yes, the quad was flying on 2.8. I flew it several times both using my radio (Spektrum DX8) and also via pre-programmed waypoints.
The quad is the ArduCopter 3DR…"
