Tried to connect as in the wiki, but no readings?

Do I have to change the I2C adress on the SF10/x, default 0x55?

Running APM:Copter V3.3.1.

Is it possible to see devices connected to the I2C bus?

How can i set the parameter RNGFND_ADDR found in wiki parameter list?

Or is it for coming version of copter?

Copter-3.3.3 claims to support the LightWare SF10/x via I2C.  I also tried to connect as in the wiki, but I don't get any readings either.  Were you able to make it work?

Hi Al

Are you able to try Copter-3.4?


But Copter-3.4 has not been released.  Did you mean Master? Can you connect via I2C with that code?  Thanks!

I'm doing some connectivity tests with the various Copter versions and LightWare devices. I'll let you know as soon as I have some concrete information.

Thanks Robert!

@Robert I am about to start testing our SF10c via I2C. How did your tests go. Any advice?

Hi Justin,

It appears that copter 3.3.3 does not support I2C for LightWare devices, however when I use the latest development version of 3.4 it works perfectly.

You also need to make sure you have the RNGFND_ADDR set to 85, which matches the SF10's default I2C address of 0x55 - the 85 is after you convert to decimal.
