Macro Definition Documentation

◆ BUCK_VIN_ADC_TRGDLY

#define BUCK_VIN_ADC_TRGDLY (uint16_t)(BUCK_VIN_ADC_TRG_DELAY / PWM_CLOCK_PERIOD)

Definition at line 462 of file epc9143_r40_hwdescr.h.

◆ BUCK_VIN_FEEDBACK_GAIN

#define BUCK_VIN_FEEDBACK_GAIN (float)((BUCK_VIN_R2) / (BUCK_VIN_R1 + BUCK_VIN_R2))

Conversion macros of input voltage feedback 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.
