   I am using FRDM-KV31F and FRDM-MC-LVPMSM boards to control a PMSM motor using Kinetis Motor Control, and I noticed that fixed point math is used for the FOC algorithm. Is it possible to use floating point math for the FOC algoritm? Why the fixed point math is used instead floating point, because as far as I know KV31 microcontroller has single precision floating point unit.
