STM32 PMSM FOC Speed Feedback

Question asked by Machfax on Oct 15, 2014
Hi

How can I get the speed into my application in rpm?
I just have the function MCI_GetAvrgMecSpeed01Hz but this is a bad resolution of the speed.
In the UI I get the speed in rpm, better in tenth of rpm/s. But with which function I get this speed?
This doesn't works:

Speed_temp = MC_Protocol_REG_t.MC_PROTOCOL_REG_MEAS_ROT_SPEED;


Please help

Regards
