Strange problem with PWM control in ANGLE mode
  • tompa
    Hi,
    I have Alexmos 32 bit controller and until yesterday it work great. But suddenly yaw axis is stop responding on PWM input! As you can see in video GUI show RC_YAW input but gimbal have not any movement! RC_PITCH work as expected. Both axes are in ANGLE mode. In SPEED mode gimbal work. The problem appeared after I changed YAW min/max angle from -180/180 to -90/90. I've put the old settings back but problem persist.
    Here is video: https://youtu.be/FqfZRhoIJLY
    As you can see in first half of video I move YAW and you can see move in GUI but YAW axe stay in place. In second half of video I move pitch and pitch axes are moving!
    Any idea where is problem?
    Thanks,
    Tom.

    Can`t figure what is wrong. Now I am put analog potentiometer on A2 but same problem. In angle mode yaw not moving but in speed mode work normaly.

    Maybe you have yaw speed 0.

    No, at any speed, 10,20,100... and any acceleration limit same problem. Something is wrong in mapping on Alexmos. Question is where, software bug or hardware. Tomorow will erase eeprom.

    ...and if I change inputs for YAW, analog A1, 2,3 or PWM RC or FC, nothing change, but if I change from angle to speed mode all inputs work!

    Is there any idea for my problem?
    I'm a bit scared to wipe out eeprom because I'm not quite clear with what sequence I'm going to pick up the system again.

    Test with the min and max limits.
