I’ve just released 3.9.11beta1. The 3.9.11 release includes two changes:
fixed the COMPASS_DEV_ID for UAVCAN compasses, which was using an uninitialised byte, and thus could result in an unpredictable ID. This caused users to have to re-calibrate unnecessarily
fixed a missing I2C ISR acknowledgement. While this never caused any issues in the plane stable release as far as we know it is safest to include this fix. This may fix an issue with SMBus smart batteries.
Hi all i have a I2C issue
i am running on the I2C bus port on a cube lightwave LW20/c with MS4525D0 airspeed sensor and a external led
when i power it up all works for about i min the led on 2 gps stops and then LW20 stop working to
and in mission planer i get bad lidar heath as well as bad compass
but if i pull out one airspeed or the lw20 does not matter witch one they all the work fine
just can run the airspeed and lw20 at the same time
anyway here are some logic scans of I2C bus with and with out air speed
and the bin logs
i did try different ID on LW20
after some testing and Googling i found out its newer chip set on digital Airspeed have an issue with other devices as i tried a new one same issue
I had old one airspeed i got last year with old chip set works fine with out an issue
any way thanks to all who helped
the First picture is off newer one for the Cube
yes i was talking to them today they where unaware of this he said
I have 3 planes all the same gear airspeed & Lw20 & external Led
same issue on all of them
one planes on 3.9.2 one on 3.9.10 and one i been testing on 3.9.11 & 4.0.0beta2 all the same results tried the old one work’s fine in all case’s
if you like i can sent it up to you just Pm a address to post it to you i am only in melbourne ?
According to the full parameters list in the Arduplane documents, there is a parameter SERIALx_OPTIONS. This parameter is required when configuring Frsky telemetry on a Matek F405 Wing according to the documentation on Matek’s Web site.
I cannot find this parameter in the latest Mission Planner full param list.
