APM - Poor startup behavior

Posted by John C. on August 19, 2010 at 9:15am
Hi all,

I know it's very early in the APM game, but I have a strange issue with the r628 code and startup.

I have to reset the AP for it to boot normally.  A regular startup puts my ESC in programming mode, with no control over the plane.

Just wondering if anyone else has run into this.


Thanks!

JC

    Many thanks for the detective work!

    As Jason Short mentioned, all these bug reports and fixes should now take place via the Issues Reporting structure on the code repository. John, can you make sure it's there; otherwise the dev team won't see it and can't evaluate the fix.

    Found a solution. Increase delay for APM_RC loading.

    I'm not sure of optimum value, but 1300ms works good for me.

    This is in system

    //delay(300); // This delay is important for the APM_RC library to work. We need some time for the comm between the 328 and 1280 to be established.

    delay(1300); // This delay is important for the APM_RC library to work. We need some time for the comm between the 328 and 1280 to be established.

    Yes, first power up, it did this to me also..but...

    made some changes to the code, re-compiled all the changes..works fine now.

    however, i cannot completely switch off throttle in FBW or STAB...

    Its not an issue, now working on that bit...

    its def in the void(ardupilot(init)) somewhere..just not nailed it yet..lol, so many proc calls..

    I will run my code changes past our fearless leaders before commiting it to all, make sre im not being a complete muppet.

    Mike.
