◆ BUCK_ISNS_OFFSET_CALIBRATION_ENABLE

#define BUCK_ISNS_OFFSET_CALIBRATION_ENABLE false

Enables/Disables Current Sense Offset Calibration.

Current Sense Offset Calibration is disabled (see notes)

Flag indicating if the signal offset of the current sense feedback needs to be calibrated. The calibration procedure is available as Special Function of the power controller and will be called automatically when the option BUCK_ISNS_NEED_CALIBRATION is set to 'true'

Note: Standby current sense feedback offset calibration is not supported by the MCP6C02 shunt amplifier device used in EPC9143 due to its limited common mode range, which starts above 2.5 V DC. However, the common reference voltage of both devices, auto-zero self tuning and high sensing precision makes calibration negligible.

◆ DBGPIN1_ENABLE

#define DBGPIN1_ENABLE false

Enables debug pin indicating control loop execution timing.

Definition at line 72 of file epc9143_r40_hwdescr.h.

◆ DBGPIN2_ENABLE

#define DBGPIN2_ENABLE true

Enables debug pin indicating task scheduler execution timing.

Definition at line 73 of file epc9143_r40_hwdescr.h.

◆ PLANT_MEASUREMENT

#define PLANT_MEASUREMENT false

Global defines used to enable/disable special firmware options.

This section is used to enable/disable special options of the firmware. If enabled, replaces the common voltage control loop by a simple P-control loop to perform measurements of the plant transfer function.
