◆ BUCK_SWITCHING_PERIOD

#define BUCK_SWITCHING_PERIOD (float)(1.0/BUCK_SWITCHING_FREQUENCY)

Conversion macros for user-declarations of PWM parameters.

These conversion macros are used to convert user settings defined as physical quantities into binary (integer) numbers, which will be written to registers and variables and used in calculations throughout the firmware. Switching period in [sec]
