Two IMU not working

[josef821]

hi. i have two Arduino uno and mpu6050. i set the port in ArduinoControllers.ini ( PORT 3 and PORT 17 ).
just port 3 working and port 17 not working. i check port 17 when game is running , it's not busy but port 3 is busy.
i set the one controller ( ShoulderYaw and ShoulderPitch has values ) with port 3, it works .
but port 17 not working even in one controller.
i test port 17 in arduino serial port.it works but not working in steamvr.

Hi, try changing port from 17 to 6 in device manager and change in TrueOpenVR settings.

thank's for quick reply.
it's work now.but port 3 move right hand and port 6 move left hand.
but as this image https://user-images.githubusercontent.com/9499881/80840516-8e1e4280-8c0e-11ea-9a5f-96a890f12d29.gif
i want to move just one hand with arm and foream.
what should i do for that?

[r57zone]

I completely forgot. Arduino must transmit data from two sensors at once

[josef821]

so. what should i do?
Do i need to make changes to Arduino's code or c++ arduino controller ?

You need to connect 2 IMU sensors to one Arduino and slightly tweak the firmware so that the Arduino can transmit two rotations at once. The transmitted format is already described in the firmware.

Alternatively, you can just use the default, that is, use 1 rotation sensor for one hand.

i connect two sensor on one arduino.
but i don't know what change need in arduino and c++ code.
can you help me and update driver and firmware for that?

[r57zone]

Unfortunately, no, because I don't know how to connect 2 sensors correctly and change firmware for him

[int-mian]

you can parallel two sensor,and use AD0 to change their address,but i don't know how to change the firmware
