IONI Pro (FW 1.7.21) : I am struggling to understand the principle of the “raw” position feedback reported by the API with SMP_ACTUAL_POSITION_FB (and shown by Granity).
We have an absolute position encoder (BiSS-C, 26-bit), and the (absolute) position reported with SMP_ACTUAL_POSITION_FB_NEVER_RESETTING looks (absolutely) correct.
But the SMP_ACTUAL_POSITION_FB is relative, it is more-or-less reset to 0 after a power cycle, or after a restart command (with SMP_SYSTEM_CONTROL_RESTART). I write more or less because the value is not zero, but something in the range of ±500 units approximately.
Also, I observe that the reset value will be kept (the sensor not being moved, of course) after subsequent resets. Just like if some LSBs of the sensor data were not taken into account for a subtraction.
There must be something I do not understand.
