Hi. Unable to attach dataflash log, because AFAIK it never booted and detected the SD card, it always says; "no dataflash detected" on boot (or equivalent message).

tests, compass - does deliver good heading, (in started direction)

Comment by Andke on May 16, 2012 at 8:24am

Extra info; I get "No dataflash inserted" on every boot

and "COMPASS INIT ERROR"  - yet the compass is calibrated. and declination set (maybe the error won't appear if I boot it in correct direction ?) Anyway compass test displays  heading and XYZ values that look "good" except north is not actual north

Andke, check (redo) the shield soldering... make sure the pins have good contact and that the shield is really pushed down as much as possible... 

I got this Compass init error (yet calibrated...) and all I had to do was to resolder the shield in place while applying more pressure. 

Let us know how it goes.

Hi Folks,

Now that APM2 supports the optical flow I thought I would give it a try but get "Failed to initialise ADNS3080" both when trying to enable it in 2.5.5 via the terminal as well as the test sketch. 

Checked and double checked the wiring, all seems good.

Any ideas?

Thanks

Crispin

In reply to my own post - 

If this helps? I stuck some debug into the init for the ADNS3080 and it fails to read the product ID or the product id was not 0x17 so exited false.

Hello, 

I am looking for the servo_out variable in the newest Arduplane code and I cannot find where it's value is being calculated.

I found in the repository http://code.google.com/searchframe#iTqA9ErfVSM/ArduPilotMega/trunk/... this formula, which is impossible to find in the newest versions of the code.

servo_out[CH_ROLL] = PID((nav_roll - roll_sensor), deltaMiliSeconds, CASE_SERVO_ROLL, 1.0);  

servo_out[CH_PITCH] = PID((nav_pitch + abs(roll_sensor * PITCH_COMP) - pitch_sensor), deltaMiliSeconds, CASE_SERVO_PITCH, 1.0);

Can somebody help me with this? Is really important

Stefan

@Popa,

     I'm not super familiar with the arduplane code but it looks like it's stil there it's just that instead of putting the servo output into that "servo_out" array, it's being put into g.channel_roll.servo_out.  Here's the link to the equivalent place in the code.

Developer Comment by Randy on May 16, 2012 at 9:02pm

@Crispin,

     that's a sign that it's not able to communicate with the sensor.  So when it starts up it first asks the sensor for it's product id and it should reply with 0x17.  if it doesn't (like for example if it replied with 0x00 or 0xff) then the communication line is not working.  That's most likely the MISO (master in slave out) or MOSI (master out slave in) line that's not connected properly.   Of course you've followed the wiki instructions carefully.

     I'm sure you don't have a logic analyzer so it's hard to be sure what messages are passing through the lines.

     Of course, the little red light is on, on the optical flow sensor?

@Randy

I did follow the wiki. when it boots after putting the test sketch on, I get the menu but it's preceded by the error, could not initialise the sensor. If I put 2.5.5 back on and try enable it through the CLI it does not enable and returns the error. Yes, the led is on ;)

As for the logic analyser, I don't have one but don't need much of an excuse to get another toy. I could have one tomorrow if it's going to help?

Hi All

Can someone provide a short description with a photo (if possible) of how I should configure the solder bridge on APM2 (V2.4.1) to use UART2 for telemetry? Also if one does so do you lose telemetry on the UART0/2 port when the USB cable is disconnected?

Just some feedback, flew ArduPlane V 2.34 yesterday morning as my first flight after integrating the board into a  Dynam Hawk Sky. Successfully evaluated stabilize, FBW-A and RTL mode - thanks to the developers for their effort.  Still have problems with the M-TEK GPS not getting 3D-Fix when the board is powered up any way other than via the USB. I,ve just taken delivery of a uBlox GPS so I'm going to check whether it establishes lock more reliably than the M-TEK whilst powering up the board from an ESC/BEC. 

Thanks in advance.

Grant
