lean angle

[apropos]

How do I go about creating a lean angle indicator widget? I found the following on an online forum. It seems lean angle/roll can be calculated from the 3 accelerometer readings.

accelerationX = (signed int)(((signed int)rawData_X) * 3.9);
accelerationY = (signed int)(((signed int)rawData_Y) * 3.9);
accelerationZ = (signed int)(((signed int)rawData_Z) * 3.9);
pitch = 180 * atan (accelerationX/sqrt(accelerationYaccelerationY + accelerationZaccelerationZ))/M_PI;
roll = 180 * atan (accelerationY/sqrt(accelerationXaccelerationX + accelerationZaccelerationZ))/M_PI;

Hey thanks for this. I can probably add it. It would be interesting to think of how derived values could be added in a configurable way.

So in 0.67.0 there is pitch, roll, and yaw... its definitely experimental! I'm not sure if it's "useful" yet, but you can make a bar of it or perhaps even a gauge. Let me know.

thanks, i will give it a try!

@apropos - was this any use? If you have a test file that you'd be able to share it might help in the creation of a suitable widget... or any ideas about how such a widget should look? Thanks! if you are able - please use WeTransfer or similar to send to gopro-overlay [at] time4tea.net - but also, no worries if you don't feel able to share.
