ST7MC THREE-PHASE BLDC MOTOR CONTROL SOFTWARE LIBRARY
- Required ROM/RAM:
These metrics include non motor control related code, implemented for demo purposes (such
as ADC management, software time bases, etc.). Depending on the chosen memory model,
the code size produced can be smaller or larger. This must therefore be considered only as in-
dicative figures.
