FMA sensor on 2.0 code - need reverse

Posted by Robert Krogh (hooks) on May 2, 2009 at 5:39am
I have one problem with the pre test- I installed the FMA sensor just like instruction. But when I point the nose down the pitch also going down.. so I need to reverse the settings. I'm using code 2.0 and not the new 2.1How to do?Please don't tell me to reverse the FMA sensor.Also having problem making the FMA sensor working first time, I can see other having the same problem.

    Hooks,
    In the 2.0 code, try this:
    Reverse IR sensor-old code-return constrain((int)(((infrared0-511)*90)/max_ir),-60,60);
    new code-return -constrain((int)(((infrared0-511)*90)/max_ir),-60,60);
    Reverse IR sensor pitch-old code-return -constrain((int)(((infrared1-511)*90)/max_ir),-60,60);
    new code-return constrain((int)(((infrared1-511)*90)/max_ir),-60,60);
    Just reverse the sign in front of "constrain".

    You need to reverse your elevator servo. The line of code is in the first tab (set pitch to 1):

    #define REVERSE_ROLL 0 //To reverse servo roll
    #define REVERSE_PITCH 0 //To reverse servo pitch
