Pb réglage MPU 6050

Bonjour,

je viens de recevoir votre carte MPU6050 que j’ai installé avec mon Mini Arduino Pro.

J’ai installé Multiwii 2.1 mais je ne vois rien ce passer sur l’interface sauf des erreurs sur IC2. J’ai dû oublier qq chose quelque part. :angry: :angry:

J’ai même modifier l’adresse par défaut dans l’onglet Sensor pour le mettre en 0x69.

Pourriez vous me dire ce que je pourrais essayer.

Les connexions sont bonnes et la carte est bien alimentée en 5 V.

Voici la prog

/* this file consists of several sections

  • to create a working combination you must at least make your choices in section 1.
  • 1 - BASIC SETUP - you must select an option in every block.
  •  this assumes you have 4 channels connected to your board with standard ESCs and servos.
    
  • 2 - COPTER TYPE SPECIFIC OPTIONS - you likely want to check for options for your copter type
  • 3 - RC SYSTEM SETUP
  • 4 - ALTERNATE CPUs & BOARDS - if you have
  • 5 - ALTERNATE SETUP - select alternate RX (SBUS, PPM, etc.), alternate ESC-range, etc. here
  • 6 - OPTIONAL FEATURES - enable nice to have features here (LCD, telemetry, battery monitor etc.)
  • 7 - TUNING & DEVELOPER - if you know what you are doing; you have been warned

Failsafe check pulse on THROTTLE channel. If the pulse is OFF (on only THROTTLE or on all channels) the failsafe procedure is initiated.
After FAILSAVE_DELAY time of pulse absence, the level mode is on (if ACC or nunchuk is avaliable), PITCH, ROLL and YAW is centered
and THROTTLE is set to FAILSAVE_THR0TTLE value. You must set this value to descending about 1m/s or so for best results.
This value is depended from your configuration, AUW and some other params.
Next, afrer FAILSAVE_OFF_DELAY the copter is disarmed, and motors is stopped.
If RC pulse coming back before reached FAILSAVE_OFF_DELAY time, after the small quard time the RC control is returned to normal.
If you use serial sum PPM, the sum converter must completly turn off the PPM SUM pusles for this FailSafe functionality.*/
