okay Tony

one last thing from my side i have been speaking to Yure he had a similar problem this moring and he solved it by washing the the board with Acetone, might try that see what happens?

Hi , I resoldered everything again....washed the boards with aceton....system works one time...than fails again...i wait 5 hours and then i try , first shot works than failure again..

 

i have one more important question..i would appriciate if anyone can test or answer..

i unplugged everything from board, only ardupilot mega 1.4 board and i use FTDI cable...I upload ardupilot mega software...and then i enter serial monitor in that condition...serial data doesnt run until i push reset button on Ardupilot mega 1.4 and serial data starts to run..after that i unplug the ftdi cable and plug it again . when i enter serial monitor no data shows again until i push reset button on the ardupilot mega board..is this correct behavier? i appriciate for the answer.

thanks TONY

That probably means you don't have the "set RTS on close" box checked, as described here:

Yes Chris, Set RTS on close is checked as it should be...

Thanks

See if you can narrow down the problem. Does it work if you push on the board in a certain way, or if you skew it to ensure better connection with the IMU? We've found that if people solder some of the connectors on one side male and some female, when they're paired some pins don't touch. Also, please explain what you mean by "fail"-- error messages will help us diagnose.

Again, a photo of your boards apart would help.

HI Chris , I fouind the problem..It really doesnt make sense to me however please let me know your opinion: when i moved DIP switches from Down postion to Up position (4 of them) the board start to act perfectly normal..I can see GCS data running smooth , serial monitoring runs perfect , no resetting problem, cli mode acts normal , flying position acts normal .......I will contunie on my setup and i hope i dont hit further problem..However What i dont understand is Servo reversing from down to up position fixed all problem and board behaving correctly now..what does that means?

THank you..

Tony

There's no reason why the DIP switches should affect anything. I'd contact store tech support.

Hi Tony,

It's good news that you found what looks to be the issue on the board, I would say that even if there is a small question over the function of the board I would contact tech support, it would be worth it in the long run, if you have an underlying problem on the board and during use the fault reappeared it could cause an expensive experience. The other consideration is the dip switches are normally used in the down positions, so this might cause you issues further into your build.

Regards

Martin

I am really confused now..here is the answer from DIYSTORE

Quote

"The DIP switch is used for disabling different sensors on the board. For example, if you 1001 (1 means the pin is up) then ONLY the gyros sensor will show data and nothing else. If you have 0010, this means that ONLY the temperature/pressure sensor will work. So order for you board to work correctly, you need to have all the pins up. If all the pins are down, 0000, then nothing will work. THe servos have nothing to do with the DIP switch. Your board sounds okay to me. I hope this clarifies more."

 

here is the link from manual about DIP switches:

http://code.google.com/p/ardupilot-mega/wiki/Reversing

 

please read this information , what is right what is wrong? it doesnt make sense ..please advise guys ...please

 

Regards, TONY

There is definitely some confusion here. The DIP switches are interpreted by the software. Different code uses the DIP switches differently. The link from the manual you provide is how the APM software uses the DIP switches. The ArduCopter code uses them differently, as shown here. The store tech support person was presumably talking about yet some other software (maybe the demo software?)

 

Can you PM me the email from the store, so I can know who it came from and help ensure that the answers are a bit clearer going forward?

servo reversing on the APM sounds like a bad idea except for cam stabilization or if your flying thru xbee but even then when you switched to manual it would be reversed (unless i misunderstood  how the mux works) .i,m using the RC2 NG heli code what do the dips do on it ?

at that point, i wish i would choose Uav Dev board.it has been terible experienece from the start

thanks...
