@sysdl132 Great, i will take the time to try。

Pin 25 might work

Thanks for the heads up, looks cool. Will definitely try it out

HI @AndreaF the space is a little tight, but perhaps you can put it in sideways and solder things to the right place via a few extra wires. As you can see in the picture of env hat below, the SDA of your TOF module should be connected to pin G0 and the SCL should be connected to G26 0_1579658678840_env_hat_01.jpg

Thanks for the Twitter link, i've reached out to see if he can help.

I did figure out how to do a rudimentary calibration by waiting for a button press and then setting the current values for roll and pitch to "offset" values and "correcting" subsequent readings using them. It works well enough for now, and I can calibrate in different orientations.

The only issue now is that this just uses the magnetometer, I think... I'm only reading &roll and &pitch from IMU.getAhrsData(), i'm not reading the gyro values. So this is susceptible to motion, if I slide the unit from side to side on the table the horizon tilts when it should stay horizontal.

@robalstona Thanks, I did a try and it worked! However, line of code I got went through my wall ^^
Thanks

Stereo is working (now with the latest update) when pin 35 is pulled high.

I made this and tested it ;

hi, wich ino file I have to upload to visualize "thermal distance?

awesome !

@chriswr Ok solved.. disable the watchdog..

disableCore0WDT();
