Hi All,
I’m building a tricopter with navio2. I calibrated the esc-s by the radio controller, sensors with the QGC.
I have 2 problem. When i push the throttel the first two motors spin up but the rear does not.
My 2nd problem is that the yaw servo does not do anything.
Hardware config:
upper right motor: pin1
upper left motor: pin2
rear motor: pin3
yaw servo: pin4
px4.config:
uorb start
param load
#param set SYS_LOGGER 1
#- It sets the default configuration (eg. 4001=quad_x)
param set SYS_AUTOSTART 14002
#param set SYS_AUTOCONFIG 1
param set MAV_BROADCAST 1
sleep 1
param set MAV_TYPE 2
#- 9DOF sensors
df_lsm9ds1_wrapper start -R 4
#df_mpu9250_wrapper start -R 10
#- Temperature and pressure sensor
df_ms5611_wrapper start
gps start -d /dev/spidev0.0 -i spi -p ubx
sensors start
commander start
navigator start
attitude_estimator_q start
position_estimator_inav start
land_detector start multicopter
mc_pos_control start
mc_att_control start
#- MAVlink listen on port 14556
mavlink start -u 14556 -r 1000000
sleep 1
mavlink stream -u 14556 -s HIGHRES_IMU -r 50
mavlink stream -u 14556 -s ATTITUDE -r 50
#mavlink start -d /dev/ttyUSB0
#mavlink stream -d /dev/ttyUSB0 -s HIGHRES_IMU -r 50
#mavlink stream -d /dev/ttyUSB0 -s ATTITUDE -r 50
navio_sysfs_rc_in start
navio_sysfs_pwm_out start -m ROMFS/px4fmu_common/mixers/tri_y_yaw-.main.mix
#navio_sysfs_pwm_out start
logger start -t
mavlink boot_complete
Thanks a lot!
