Hi, sorry, i for some reason cannot find what is the exact meaning/purpose of the COMPASS_DIA_X , COMPASS_DIA_Y, COMPASS_DIA_Z params?
Was there an article somewhere on what is the ‘soft-iron calibration matrix’ is? Is it something new?
so, no one knows what are those new options with a ‘soft-iron calibration matrix’ descriptions? no reference to that stuff at all? i hate to go dig into code to find who/when added all that to the master and what does it do.

Ps. It’s there since ages.
what are default values for those DIA params and how it could have been set to various values? i am dealing wiht some mishap in my configs, most likely.
Those parameters are set by compass calibration.
