Software requirements
To customize, compile and download the " STM32 FOC firmware library v2.0 " motor control
firmware, the IAR tool " EWARM v5.20 (or v5.11)" must be installed. The free 32-k limited
version (referenced as the "KickStart" version) is available for downloading at:
http://supp.iar.com/Download/SW/?item=EWARM-KS32-442A .
Software modifications
The " STM32 FOC firmware library v2.0 " is compatible with the L6386 high-side driver. To
make the firmware compatible with the L6390, you must change the polarity of the PWM
driving the low-side transistors.
To do so, Follow these steps.
