Hello,
I’ve made a traditionnal heli on a 450 size.
It fly very well with copter 4.0.3
I decide to add a lidar for altitude and 3 ultrasonic sensors for proximity.
lidar is TF Luna on serial 4
prox sensors are radiolink sui04 on I2C
Some questions about this:
_How to test the 4 sensors?
_How to set the I2C address of the 3 SUI04? (I used the switch to define each one position)
_pre-arm check always tell me “check proximity sensor”
